The Gifts You Give Your Future Skin

My son recently turned three, and all he has wanted to do was race and play with me. We spent the afternoon running, laughing and trying to beat each other to the finish line. While I was playing with him, I was thinking about how many more moments like this I wanted to have. I want to be able to keep up with him as he grows, to stay active with him for as long as possible.

That realization made me think about health in a different way. Some of the choices we make today are really gifts to our future selves. Taking care of our bodies gives us the chance to stay present for the people and activities we love later. It made me start thinking about what other long-term gifts I could give myself — including protecting my skin.

If you could give your future self a gift, what would you want? Most people think of money, memories, or something meaningful. One of the best gifts you could give is healthy skin. Your skin remembers everything — the sun, the smiles, and the seasons. The habits you build now can affect your skin’s long-term health.

The good news is that daily choices can protect your skin over time.

Gift #1: Daily Sunscreen

This is the most important one.

Up to 90% of visible skin damage is caused by ultraviolet (UV) exposure which leads to wrinkles, dark spots, uneven texture, and loss of firmness.

Even on cloudy days, UV rays still reach your skin. A broad-spectrum sunscreen with SPF 30 or higher helps protect against both UVA (aging rays) and UVB (burning rays).

Gift #2: Protective Clothing

UPF-rated clothing acts like built-in sunscreen, blocking a large portion of UV rays before they reach your skin. Consider, wide-brim hats, sunglasses, UPF-rated shirts, and shade between 10am–4pm when the sun is strongest can significantly lower exposure during peak hours.

Gift #3: Consistency

You don’t need a complicated 10-step routine. The basics matter most: sunscreen for protection, and a gentle cleanser and moisturizer to support the skin barrier.

A gentle cleanser helps remove sweat, oil, sunscreen, and daily pollution without stripping the skin. Look for labels such as “fragrance-free,” “for sensitive skin,” or “hydrating cleanser.”

Moisturizers help repair and maintain the barrier so skin stays comfortable and resilient. Ingredients like ceramides, glycerin, hyaluronic acid, and petrolatum are especially helpful. For best results, apply moisturizer within a minute after washing.

When to apply?

Morning:

Cleanse → Moisturize → Sunscreen

Night:

Cleanse → Moisturize

Gift #4: Healthy Lifestyle Choices

Your skin also responds to everyday habits. Staying active, drinking water, and eating fruits and vegetables all support normal skin function and healing. Avoiding smoking is especially important, since tobacco smoke breaks down collagen and speeds up premature aging.

Gift #5: Skin Checks

Early detection saves lives.

Check your skin regularly for new or changing spots. See a healthcare professional if you notice:

Asymmetry
Border irregularity
Color variation
Diameter >6mm
Evolving (changing)

Skin cancer is highly treatable when caught early

Your Future Skin Is Built Today

The habits you practice now — wearing sunscreen, seeking shade, and checking your skin — are small daily choices that help prevent damage and protect your health over time. They may seem minor today, but over years they add up to real protection. Taking care of your skin isn’t just about appearance. It’s about preserving function, preventing disease, and staying present for the people and moments that matter most. Give your future self a gift your skin will remember.

Stay Sun-Smart with a Wide-Brim Hat

Why Wear a Wide-Brimmed Hat?

Who doesn’t love a sunny beach day, a scenic hike, or a backyard BBQ? Soaking up the warm sunlight, spending time with friends, and enjoying the outdoors can feel energizing and refreshing. But too much sun exposure? Not so much fun.

UVA and UVB rays don’t just cause sunburn, they accelerate skin aging and increase the risk of skin cancer. Long-term exposure also raises the chances of developing conditions like melasma and vitiligo. Goh et al. found that these pigmentary disorders have the most significant negative impact on quality of life, as they are often resistant to treatment and prone to recurrence (2023). The good news? Proper sun protection can help prevent them.

And there’s an easy (and stylish!) fix: a wide-brim hat.

Big Brim, Big Benefits

Dr. Nern recommends wearing a hat with at least a 4-inch brim for 360-degree protection, shading your face, neck, and ears. When shopping, opt for broad-brimmed bucket hats or legionnaire-style hats instead of baseball caps, which leave parts of the face, ears, and neck exposed (Gies et al., 2006).

For added safety, Dr. Nern suggests hats labeled with a UPF (Ultraviolet Protection Factor) rating. UPF-rated fabrics are thicker and more durable, providing excellent defense against harmful UV rays. The higher the UPF, the better the protection. Many brands now offer UPF 50 hats as the standard. Plus, they’re low-maintenance—just wash and dry them after frequent use, and they’re ready to protect you again.

Make It a Sun-Smart Combo

While a wide-brim hat offers significant protection, Backers et al. show that no hat provides 100% coverage due to factors like wearing angles and diffused UV radiation (2018). For full protection, pair your hat with sunglasses and sunscreen—it’s like assembling your ultimate sun-shielding squad.

Stylish & Functional for Every Occasion

Wearing a hat for sun protection is still uncommon in North America. Some schools even restrict outdoor hat-wearing due to concerns about disruptions or associations with gang culture (Bray, 2016). However, this thinking can be detrimental to skin health since Linos et al. suggest that shade and protective clothing may be more effective than sunscreen, as commonly used by Americans (2011).

It’s all about shifting your mindset! In countries like China, Indonesia, and Japan, wearing hats is both fashionable and practical, making them a staple accessory (Goh et al., 2023). Whether you’re a beachgoer, hiking enthusiast, city explorer, or gardening lover, there’s a stylish hat to complement your look.

Your Skin Will Thank You

Sun protection doesn’t have to be complicated. A wide-brim hat is an easy, stylish, and scientifically backed way to reduce sun damage. So, the next time you step outside, pop on that hat, rock your sun-smart style, and give your skin the protection it deserves!

Dr. Karen Nern’s Expert Guide

When choosing a sunscreen, the list of ingredients on the back of the bottle can be overwhelming! With so many options, it’s important to know which ingredients provide the best protection and which ones to avoid. In this article, board-certified dermatologist, dermatologic surgeon, and Medical Director of The Sun Bus, Dr. Karen Nern, MD, MBA, FAAD, breaks down the essentials to help you choose the best sunscreen for yourself and your loved ones!

Best Sunscreen Ingredients for Broad-Spectrum Protection

1. Zinc Oxide and Titanium Dioxide

Dr. Nern recommends looking for sunscreens that contain zinc oxide and titanium dioxide - two mineral-based (physical) sunscreen ingredients known for their broad-spectrum UV protection.(1,2) Unlike chemical sunscreens, these minerals create a physical barrier that reflects UV rays away from the skin.

✔ Why They’re Great:

● Provide broad-spectrum protection against both UVA and UVB rays

● Ideal for sensitive skin (gentle and non-irritating)

● Reef-safe and environmentally friendly

● Offer immediate protection upon application (no wait time needed)

2. Avobenzone

If you’re looking for a chemical sunscreen, avobenzone is one of the few FDA-approved ingredients that provides broad-spectrum protection.( 3) It’s particularly effective against UVA rays , which penetrate deep into the skin and contribute to premature aging and skin cancer.

✔ Why It’s a Good Option:

● Absorbs UVA rays efficiently

● Often found in combination sunscreens to enhance protection

● A good alternative for those who prefer lightweight, non-mineral formulas

Sunscreen Ingredients to Avoid

While some ingredients provide effective sun protection, others can cause irritation or allergic reactions.

1. Oxybenzone

Dr. Nern advises against oxybenzone, as it may cause irritation or allergic reactions.4

�� Why You Should Avoid It:

● Common cause of sunscreen allergies (can trigger rashes and irritation)

Oxybenzone is frequently found in organic (commonly called chemical) sunscreens, but given its potential risks, it’s best to opt for safer alternatives like zinc oxide, titanium dioxide, or avobenzone-based formulas.

Other Tips for Choosing a Sunscreen

● SPF Matters: Choose a sunscreen with at least SPF 30 for daily use and SPF 50+ for extended outdoor activities.

● Water Resistance: If you’ll be swimming or sweating, opt for a water-resistant formula.

● Check the Labels: Look for sunscreens labeled “broad spectrum” to ensure they protect against both UVA and UVB rays!

● Avoid Fragrances and Harsh Additives: These can be irritating, especially for sensitive skin.

Dr. Nern’s go-to Sunscreen Products

● For beach or water sports:

EltaMD UV Sport Broad-Spectrum SPF 50+

● For daily use and acne-prone skin:

EltaMD UV Clear Broad-Spectrum SPF 46

● For a silky texture and to replace makeup:

Epionce Daily Shield Tinted SPF 50

Choosing the right sunscreen is one of the most important steps you can take to protect your skin from sun damage, premature aging, and even skin cancer. With so many options on the market, it’s important to know which ingredients offer the best protection without compromising your skin’s health. Dr. Nern’s expert guidance highlights the importance of choosing safe and effective ingredients like zinc oxide, titanium dioxide , and avobenzone , which provide broad-spectrum coverage while being gentle on skin. By making informed choices, you can confidently enjoy time outdoors while keeping your skin healthy, radiant, and well-protected.

The UV index plays a vital role in understanding and practicing effective sun protection. "The UV index measures the strength of UV radiation at a specific time and place," explains Dr. Nern. A higher index means a greater risk of skin damage." By offering a clear and accessible way to gauge the risk of UV exposure, the UV index empowers individuals to take proactive steps to protect their skin and overall health.

UV radiation, though invisible to the naked eye, has significant effects on the skin. Prolonged exposure to UV rays can lead to sunburn, premature aging, and an increased risk of skin cancer, including melanoma. It can also harm the eyes, causing cataracts and other vision issues, and suppress the immune system. The UV index helps mitigate these risks by providing real-time information about UV radiation levels, allowing individuals to plan their outdoor activities and sun protection measures accordingly.

The UV index ranges from 0 to 11+ , with higher values indicating greater UV radiation levels and a higher risk of harm from sun exposure. The scale is divided into categories to make it user-friendly:

0-2 (Low) : Minimal risk. Standard sun protection, such as wearing sunglasses, is typically sufficient.
3-5 (Moderate) : Moderate risk. Seek shade during midday hours, and wear protective clothing, sunglasses, and sunscreen with SPF 30 or higher.
6-7 (High) : High risk. Minimize sun exposure during peak hours (10 a.m. to 4 p.m.), and apply broad-spectrum sunscreen liberally. Reapply every two hours or after swimming or sweating.
8-10 (Very High) : Very high risk. Take all recommended precautions, including staying indoors during midday hours, if possible.
11+ (Extreme) : Extreme risk. Avoid sun exposure altogether and take maximum protective measures, including wearing full-coverage clothing and using umbrellas or shelters.

Knowing the UV index helps tailor sun protection strategies to the specific conditions of the day. "If the UV index is 6 or higher, take extra precautions, including wearing sunscreen, a hat, and sunglasses," Dr. Nern advises. Similarly, when the UV index is in the "Extreme" category, it’s crucial to avoid outdoor activities during peak hours or ensure you are fully covered and shielded.

The UV index is especially important for individuals with higher vulnerability to UV damage, such as those with fair skin, a history of skin cancer, or photosensitivity disorders. Children, too, are particularly susceptible to UV-related harm, as their skin is more delicate and easily damaged by the sun.

Modern technology makes it easier than ever to monitor the UV index. To find the UV index in your area, check weather apps, The Sun Bus or other websites, or the EPA’s SunWise tool. Wearable devices are also available to track UV exposure in real time. Incorporating this data into daily routines can make a significant difference in your skin health.

The UV index is an invaluable tool for promoting sun safety. By understanding and applying UV index information, individuals can make informed decisions about outdoor activities and sun protection, ultimately reducing their risk of sunburn, premature aging, and skin cancer.

The Impact of Sun Damage on Aging Skin | Dr. Karen Nern on Staying Youthful

Whether it's a sunny day outdoors or a weekend at the beach, spending time in the sun feels great — but too much of it can quietly age your skin faster than you'd think.

How the Sun Sneaks Up on Your Skin

There are three types of UV radiation: UVA, UVB, and UVC. All three types contribute to skin damage, but UVA is most often associated with aging and pigmentation, or uneven skin tone. Basically, the sun can mess with almost everything your skin does.

● Over time, sun damage can cause irritation, itchiness, or dry skin, which may weaken your skin’s natural ability to protect the rest of your body.

● Your body also contains sweat glands and your skin helps regulate body temperature through sweat! However, sun aging may damage sweat function, and many elderly people may be more sensitive to hot temperatures.

● Your skin normally heals wounds quickly through the regeneration of cells, but photoaging from the sun may slow this process or even reduce the strength of newly healed skin.

● Melanin is the natural pigment in your skin — it gives your skin and hair their color. Sun damage can reduce your skin’s production of melanocytes, or cells that produce melanin, and cause uneven pigmentation or skin tone.

● Your skin also has nerves that allow you to feel sensations, such as touch or pain. When the skin receives increased amounts of sunlight, there are reduced nerve endings, which may lead to reduced sensory perception.

● The dermis of the skin (below the epidermis, or the top layer of the skin) is composed of collagen and elastin, which allows it to be flexible and resilient. UV rays from the sun can break down the collagen and elastin in your skin, which causes wrinkles, decreased skin strength, and sagging.

The Fix? Protect Your Skin Like a Pro:

The good news is that the consequences of photoaging mentioned above can be prevented. Let’s talk about how you can keep your skin looking great for years to come.

● Wear protective clothing (long sleeve shirts, dark colors, jackets, sunglasses, hats, etc.)

● Always use broad spectrum sunscreen with an SPF (sun protection factor) of at least 30 — Daily sunscreen use is the best anti-aging product you can invest in. Sunscreen provides a barrier to the skin so that light may be reflected and scattered. Both broad spectrum chemical and physical sunscreens reduce UV light exposure when applied correctly.

● Check your skin daily for any changes or new spots. Lightening creams may be applied for areas of uneven skin tone.

● Avoid long sun exposure if possible and the use of tanning beds (seriously, skip them!)

● Use topical vitamins like C and E, which can increase collagen synthesis and provide nutrients to the epidermis.

● You can also use ferulic acid, which is found in the cell walls of seeds, leaves, and roots of fruits, vegetables, cereals, and grains, to protect against skin aging.

● Retinol (both prescription and non-prescription options) can be applied daily to improve inflammation, fine lines and wrinkles, and hyperpigmentation.

Taking care of your skin now doesn’t just help you look good later—it keeps your whole body strong, healthy, and protected. So grab your sunscreen, throw on a hat, and start those good skin habits today. Your future self will thank you!

Can you get sunburned on cloudy days? Myth-busting with Dr. Karen Nern

Tue, 13 Jan 2026 22:38:16 GMT

Rebecca Bolen

OMS - Rocky Vista University

If you’ve ever come home from a cloudy day outdoors only to find yourself red and sunburned, you’re not alone. Many people assume that overcast skies provide protection from the sun’s harmful rays, but that’s a dangerous misconception. As Dr. Nern explains, “Up to 80% of UV rays penetrate through clouds. That’s why sunscreen is a daily must, rain or shine, and summer or winter.”

The sun emits two main types of ultraviolet (UV) rays that impact our skin:

● UVA rays penetrate deep into the skin, contributing to premature aging.

● UVB rays are responsible for sunburn and play a key role in the

development of skin cancer.

Even when the sun is hidden behind clouds, these rays still reach your skin. In fact, certain cloud formations can even amplify UV exposure by scattering and reflecting the rays, leading to unexpected sunburns.

The “Sneaky Sunburn” Phenomenon

The reason people often underestimate the sun’s strength on overcast days is that UV rays aren’t always directly tied to temperature or brightness. A breezy, cool day may feel pleasant, but it doesn’t mean you’re protected from the sun. This false sense of security leads many to skip sunscreen, making them more vulnerable to UV damage.

Winter Sunburns?

Yes, They Happen!

While most people associate sunburn with the beach, winter conditions can be just as hazardous, if not more so. Snow and ice reflect up to 90% of UV radiation , effectively exposing your skin to nearly double the amount of UV light compared to non-snowy conditions. That’s why skiers and snowboarders often get sunburned, even in freezing temperatures.

Dr. Nern emphasizes the importance of sun protection year-round. Whether you’re on the slopes or taking a winter hike, sunscreen should be a non-negotiable part of your routine.

How to Protect Your Skin Every Day

Since UV exposure is consistent regardless of weather or season, adopting daily sun protection habits is essential.

Here’s how you can safeguard your skin:

Seek shade – Whenever possible, stay in shaded areas, especially between 10 AM and 4 PM, when UV rays are strongest.
Apply sunscreen every day – Use a broad-spectrum sunscreen with at least SPF 30 , even on cloudy days. Don’t forget to reapply every two hours, especially if you’re outdoors for extended periods.
Wear protective clothing – Long sleeves, hats, and sunglasses help block UV rays. Consider UV-protective clothing for added defense.
Use lip balm with SPF – Lips are often overlooked but are just as vulnerable to sun damage.
Be mindful of reflective surfaces – Snow, sand, and water all reflect UV rays, increasing your exposure.

Final Thoughts

Just because you can’t see the sun doesn’t mean it isn’t affecting your skin. UV rays are persistent, and their impact accumulates over time, leading to premature aging, sunburn, and even skin cancer. By making sun protection a daily habit, no matter the weather, you’re taking a crucial step in preserving your skin’s health. As Dr. Nern reminds us, “Your skin will thank you for it.”

Are Tanning Beds Safe? The Truth from Dr. Karen Nern

Tue, 16 Dec 2025 22:54:56 GMT

David Perez, MS-3

Georgetown University School of Medicine

If you have ever used or considered using a tanning bed, that’s enough exposure! It’s time to close that door for good!

Like sunlight, tanning beds give off ultraviolet radiation (UVR). Your body produces melanin, the pigment that affects skin color, to help protect against the damage that UVR has on DNA.¹ Tanning beds can produce 10 to 15 times more UVR than the sun.²Using a tanning bed just once increases the risk of melanoma—the deadliest form of skin cancer—by 20%, and each additional session per year raises the risk by 1.8%.³ Because of these dangers, many countries have restricted or banned tanning beds.⁴ Board-certified dermatologist Dr. Nern warns, "There’s no such thing as a safe tan from a tanning bed .

Tanning beds can cause different types of skin cancer. Melanoma is responsible for over 80% of skin cancer deaths.⁶ It develops from the cells that produce melanin and can affect all skin tones. Using tanning beds before age 20 increases your risk of melanoma by 47%.⁷ Other common skin cancers, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), form in the outer layer of the skin.⁸ Indoor tanning raises the risk of BCC by 24% and SCC by 58%.

Not only do tanning beds increase your risk of developing skin cancer, but they can also cause burns, loss of consciousness and eye damage, all of which can require hospital treatment. In addition to these consequences, tanning beds also cause premature skin aging, including the development of wrinkles, fine lines, sagging skin, and age spots. ⁹

If you would like the “bronzed look” without the risk of skin cancer, Dr. Nern advises opting for self-tanning products, which come in various forms including sprays, mousses, and lotions. Self tanning products contain a compound that reacts with the top layer of your skin to create a temporary tan.¹⁰ In addition to being convenient to use, they offer different colors in order to suit different skin complexions. Self-tanning products also allow greater control over the tanning process. The product can be reapplied several times to gradually develop color for a more natural look. They make it possible to avoid unwanted patches of discoloration or tan lines that normally result from excessive sun exposure.

So, next time you think about tanning, we hope you reflect on your skin's well-being and choose

the safe and equally effective alternative, your future self and loved ones will thank you!

Driving Change: Lessons I’ve Learned on the Road with The Sun Bus

The roads I know best are two-lane highways—quiet stretches through farmland, small towns, and forests. Growing up in rural Wisconsin, I learned early on that healthcare often meant travel. A check-up could require hours of driving, missed work, and out-of-pocket expenses. For many families, it just wasn’t feasible.

That early understanding is what sparked my passion for mobile healthcare: meeting people where they are and breaking down barriers to care. It’s also why working with The Sun Bus has meant so much to me.

As a traveling dermatology assistant, I’ve spent the past year helping provide free skin cancer screenings and sun safety education in several communities—many facing the same barriers I saw growing up. In these areas, people often go out of their way to thank us for what we do, which resonates deeply with me.

Since joining The Sun Bus, I’ve met people from all over the US—at health fairs, festivals, schools, workplaces, and farmers markets. We’ve parked the bus just about everywhere, from busy city blocks to empty parking lots in quaint mountain towns. Each stop has taught me something new. After months of screenings and conversations, here are a few lessons that have stayed with me:

1. Prevention Saves Lives

In a sunny state like Colorado, prevention is everything. A simple conversation can change someone’s life. I’ve seen people come up to the bus just to ask a quick question and end up getting checked for something serious. We’ve found suspicious spots that people didn’t even know were a problem. Seeing those patients get the care they needed reminded me how powerful screenings and preventative care can be.

2. Education is a Superpower

Whether I was explaining the ABCDEs of skin cancer or using the VISIA camera to reveal hidden sun damage, I saw how curious people are about their health. Helping turn that curiosity into action—like wearing sunscreen or reducing time spent in the sun—was a powerful reminder of how education can inspire lasting change. Giving people the knowledge to care for their skin, often for the first time, felt like a meaningful step toward long-term health and prevention.

3. Mobile Care Reaches People Who Need It Most

Many people we screened hadn’t seen a dermatologist in years—if ever. Some lived hours from the nearest clinic or didn’t have insurance. By showing up in their neighborhood, we removed those obstacles. This showed me that mobile clinics like The Sun Bus are proof that care doesn’t need an address.

As I wrap up my time on the road, I’m excited to carry these lessons with me into my next chapter. I’m looking forward to starting medical school at the University of Wisconsin–Madison, where I’ll be part of the rural medicine program. It feels like coming full circle—returning to the same place that shaped my view of healthcare, now equipped to give back in new ways.

I’ll always be grateful for what The Sun Bus taught me: that prevention matters, education empowers, and access to timely, affordable healthcare can change lives.

I want to say thank you to the amazing team I’ve worked with, the providers who have shared their wisdom, and the patients who have shared their stories.

If you see The Sun Bus in your town—don’t miss it! You might just walk away with a little more knowledge, a lot more sunscreen, and maybe even a skin check that could change your life.

Sun Safety for Babies and Children: Dr. Karen Nern’s Family-Friendly Advice

Thu, 20 Nov 2025 17:33:15 GMT

Jennifer Cucalon, MD, PGY-1 Resident

As warm weather increases, so does family time outdoors, but it also brings increased exposure to the sun’s harmful rays. Whether you’re planning a beach trip, a walk in the park, a picnic, or just playing in the backyard, sun safety for babies and children is essential for preventing sunburns, skin irritation, and long-term damage like premature aging or skin cancer. Even short bursts of unprotected sun exposure can have lasting effects, especially on delicate, developing skin.

Dr. Karen Nern, a board-certified dermatologist and mother, offers simple, science-backed guidance to help families keep their children safe in the sun, starting from the very beginning.

Babies Under Six Months: Keep Them Out of the Sun

“Babies under six months should be kept out of direct sunlight,” says Dr. Nern.*

Infants have especially delicate and sensitive skin that’s thinner than that of older children and adults, making them significantly more vulnerable to the sun’s ultraviolet (UV) rays. Protecting them through physical barriers and strategic shade is the best approach.

Use stroller covers, canopies, or umbrellas to block direct sun
Dress babies in lightweight, breathable long-sleeved clothing that covers arms and legs
Add a wide-brimmed hat to shield the face, ears, and neck

Even brief exposure to intense midday sun can lead to a burn, so always be prepared with portable shade options when heading outdoors. If sun exposure is unavoidable, consult a pediatrician before applying a small amount of mineral-based sunscreen (such as zinc oxide) to very limited areas.

Older Children: Build Lifelong Sun Safety Habits

“Make sun safety a habit early. It’s a lifelong gift you can give your kids,” says Dr. Nern.**

Dr. Nern’s Sun Safety Tips for Children:

Apply sunscreen generously to all exposed skin, especially areas that are often missed like the face, ears, neck, and tops of the feet. Make it part of your morning routine before heading out.
Choose a broad-spectrum sunscreen with SPF 30 or higher to protect against both UVA and UVB rays.
Reapply sunscreen every two hours , or more frequently if your child is swimming, sweating, or towel-drying, even on cloudy days.
Dress children in sun-protective clothing , including long-sleeved shirts, lightweight pants, and wide-brimmed hats that provide full coverage and comfort.
Use UV-protective sunglasses to shield their developing eyes from harmful rays, reducing the risk of eye damage and long-term vision issues.
Limit outdoor activities during peak sun hours (10 a.m. to 4 p.m.) , when UV radiation is at its strongest and most harmful.
Opt for shady play areas or bring along a portable sun tent or umbrella to create your own shade when natural options aren't available.
Lead by example —children are more likely to adopt sun-safe behaviors when they see their caregivers doing the same.

The Earlier, the Better

Starting sun protection habits early helps children recognize the value of caring for their skin. From applying sunscreen before school or summer camp to wearing hats while hiking or playing at the park, these actions become natural with practice and set the stage for long-term health-conscious behavior.

According to the Skin Cancer Foundation and recent studies by Li et al. , there is evidence that just one blistering sunburn during childhood can double the risk of developing melanoma later in life. By being consistent now, you're helping your child avoid major health risks in the future and teaching them to prioritize their well-being.

Sun safety doesn’t have to mean staying indoors. With thoughtful planning, like packing sunscreen, hats, lightweight UV-protective gear, and seeking shaded play areas, you can enjoy sunny days confidently and comfortably, knowing you're protecting your child’s skin for years to come.

Beyond Sunscreen: A Comprehensive Approach to Sun Safety

When it comes to protecting your skin from the sun’s harmful rays, sunscreen is a must, but it is not the only defense you need. "Sunscreen is essential, but it’s just one piece of the puzzle," says Dr. Nern. To fully protect your skin, it is important to adopt a multi-layered approach to sun safety. Here are Dr. Nern’s top tips for staying safe in the sun:

1. Seek Shade During Peak Hours

The sun’s ultraviolet (UV) rays are strongest between 10 a.m. and 4 p.m., making this the most dangerous time for sun exposure. If you can, seek shade under trees, umbrellas, or other shelters during these hours. This simple action can significantly reduce your risk of sunburn and long-term skin damage. However, it is important to remember that shade alone is not enough. UV rays can still reflect off surfaces like water, sand, and pavement, so additional protection is necessary.

2. Apply Sunscreen Properly

While sunscreen alone is not enough, it is an important part of sun protection. Choose a broad-spectrum sunscreen with an SPF of at least 30, and apply it generously to all exposed skin. Reapply every two hours, or more often if you are swimming or sweating. Be sure to cover commonly missed spots such as your ears, tops of your feet, and the back of your hands.

3. Wear Protective Clothing

One of the most effective ways to block UV rays is by wearing proper clothing. Long-sleeved shirts, long pants, and wide-brimmed hats can be used to cover as much skin as possible. A broad-brimmed hat not only shields one's face but also helps protect your ears and the back of your neck, which are areas often overlooked when applying sunscreen. Light, tightly woven fabrics offer better protection than thin, loosely woven material. Some clothing has even been designed with built-in UV protection, which provides an extra layer of defense against harmful rays. Brands such as Collibar, UV Skinz, Solbari, and Cabana Life have sun protective clothing with UPF 50+ which blocks 98% of UVA/UVB rays.

4. Use UV-Blocking Sunglasses

Your eyes are also vulnerable to UV radiation, which can lead to serious conditions like cataracts and macular degeneration over time. Wearing UV-blocking sunglasses helps to protect your eyes from sun damage and reduces the risk of long-term vision problems. When choosing sunglasses, look for labels indicating they block 100% of UVA and UVB rays. Polarized sunglasses will help reduce glare and reflection off surfaces like water. Additionally, larger lenses and wraparound-style sunglasses can provide more coverage.

The Best Protection Comes from a Combination of Strategies

"By combining these strategies, you’re giving your skin the best protection possible", says Dr. Nern. Sun safety isn’t just about avoiding sunburn, it’s about reducing your risk of skin cancer, preventing premature aging, and eye damage. Making these habits part of your daily routine will help ensure that you can enjoy the sun safely for years to come.

Remember, sun protection is a year-round effort, even on cloudy days and during the winter months. By staying proactive, you can keep your skin healthy and radiant while minimizing the risks associated with UV exposure.

How Often to Reapply Sunscreen

Many assume that applying sunscreen once in the morning is enough, but that’s not the case. Sunscreen should be applied 15 minutes BEFORE you are exposed to ultraviolet (UV) rays and then reapplied throughout the day to maintain its effectiveness, and we’re here to explain why.

So, you’ve found the perfect sunscreen, one that blends seamlessly into your skin, doesn’t leave a white cast, and works well with your skincare routine. That’s a huge win! But now comes the next step: How often should you reapply sunscreen? Yes, you need to reapply your sunscreen! Many assume that applying sunscreen once in the morning is enough, but that’s not the case. Sunscreen should be applied 15 minutes BEFORE you are exposed to UV rays and then reapplied throughout the day to maintain its effectiveness, and we’re here to explain why.

Why Does Sunscreen Need to Be Reapplied?

I spoke with Dr. Karen Nern, MD, a board-certified dermatologist, who explains that many people underestimate how quickly sunscreen can wear off, stating that sunscreen should be reapplied “Every two hours. Even water-resistant formulas need to be reapplied to maintain their effectiveness.”

Sunscreen is designed to protect your skin from harmful UV rays, which can cause sunburn, premature aging, and skin cancer. ¹ But it doesn’t last all day. Several factors can cause sunscreen to wear off. Physical activity or heat can lead to sweating, which can degrade the ingredients in sunscreen over time. While water-resistant sunscreen can help to diminish barrier protection during water exposure, it can still degrade with extended exposure and needs to be reapplied. ² Once you get out of the pool or finish your activity, drying off with a towel can remove your sunscreen. If you plan to stay in the sun, make sure to reapply to ensure full coverage. In your day to day, natural skin oils and touching your face can reduce sun protection.

Okay, so I only need to reapply sunscreen if I am outdoors? While it’s true that UVB rays - which cause sunburn - are mostly blocked by windows, UVA rays can still penetrate glass and contribute to premature aging and skin damage. ^1,3

Additionally, blue light from screens may impact skin health, leading some experts to recommend sunscreen use even indoors. If you work near a window or use screens for long hours, consider reapplying, especially on exposed areas like your face, neck, and hands.

Tips for Reapplying Sunscreen

Choose an SPF 30 sunscreen at least.
Set a reminder to reapply every two hours, especially if you’ll be outdoors.
Find a good makeup-friendly sunscreen to make reapplication easy.
Sunscreen powder, SPF-infused cushion compacts, or spray are some options.
Use water-resistant formulas if you plan to swim or sweat.
Don’t forget your ears, neck, hands, and scalp. These areas are often neglected.

Sunscreen is one of the most important steps in any skincare routine, but applying it once isn’t enough. No matter the weather or the activity, reapplying every two hours is a key habit to keeping your skin healthy and protected. Keep your sunscreen handy, set reminders, and don’t forget to reapply!

How to Choose the Right Sunscreen: Expert Advice from Karen Nern, MD

When it comes to sun protection, sunscreen is your first line of defense. But with so many options, how do you choose the right one? According to Dr. Karen Nern, board-certified dermatologist, Mohs micrographic skin surgeon, and co-founder of The Sun Bus, it’s all about understanding what your skin needs.

"Look for a broad-spectrum sunscreen with an SPF of at least 30," advises Dr. Nern. "Broad-spectrum means it protects you against both UVA and UVB rays, which are both harmful to your skin." UVA rays go deeper into the skin and can cause loss of elasticity as well as sun damage that can lead to skin cancer. UVB rays cause burning, which can also lead to skin cancer. Without this dual protection, your skin remains vulnerable to long-term damage.

Water resistance is another crucial factor. Activities like swimming or outdoor exercise often result in sweat or water exposure, reducing sunscreen’s effectiveness. Choosing a water-resistant product ensures that your skin remains protected during these activities. However, it’s equally important to remember to reapply, as even the best sunscreens lose their effectiveness over time. Water-resistant sunscreens, which can last on wet or sweaty skin for up to 80 minutes. For sunscreens that are not waterproof or sweatproof, they will need to be reapplied every two hours or after swimming or sweating.

Dr. Nern also recommends considering your skin type. " If you have sensitive skin, mineral sunscreens with zinc oxide or titanium dioxide are often a better choice because they’re less likely to cause irritation and are a very effective option ." Zinc oxide and titanium dioxide act as physical barriers that sit on the skin’s surface, reflecting harmful rays away from the skin. Unlike chemical sunscreens, which absorb UV rays, mineral options are less likely to cause irritation or allergic reactions, making them ideal for children and those with delicate skin.

Sunscreen is the number one tool to fight skin cancer, the most common kind of cancer in the US. While sunscreen is an essential defense, it’s not the only measure you should take. Wearing protective clothing, such as long-sleeved shirts, pants, and wide-brimmed hats, enhances your protection. Seeking shade during peak sunlight hours, typically between 10 a.m. and 4 p.m., further reduces your exposure to harmful rays.

Pro Tip: Sunscreen application techniques are just as important as the product itself. Apply sunscreen generously about a shot glass worth for your body and reapply every two hours, especially after swimming or sweating. Many people apply too little, which can significantly reduce the level of protection. Reapplication is equally vital, especially after swimming, sweating, or towel drying.

By combining these protective strategies and selecting the right sunscreen for your needs, you can significantly reduce your risk of developing skin cancer. Regular use of sunscreen, along with other sun safety practices, helps maintain healthier, younger-looking skin and provides peace of mind as you enjoy outdoor activities. Remember, sun protection is not just a summer priority; harmful UV rays are present year-round, even on cloudy days.

Making informed choices about sun protection is an investment in your long-term health. With guidance from experts like Dr. Nern and simple adjustments to your daily routine, you can keep your skin safe and radiant for years to come.

Sulfites and Your Skin: The Secret Trigger Behind Rashes and Reactions

Sulfite Allergens and Contact Dermatitis:

What You Need to Know

In recent years, concerns about food allergens have gained widespread attention, but one group of compounds often flies under the radar: sulfites. These inorganic preservatives are commonly found in everyday foods and beverages from wine and dried fruit to sodas and medications. While useful for extending shelf life and preventing discoloration, sulfites can trigger serious allergic reactions and may play a hidden role in contact dermatitis.

What Are Sulfites?

Sulfites are chemical compounds that release sulfur dioxide, a gas that acts as a powerful antioxidant and antimicrobial. They're used to preserve the color, flavor, and freshness of foods such as fruit juices, seafood, baked goods, and alcoholic beverages. Sulfites also occur naturally through the fermentation process, especially in wine and beer.

Though sulfites have been approved for use by the FDA, any food or drink that contains 10 parts per million (ppm) or more must be labeled accordingly. However, labeling doesn't always guarantee safety, particularly for individuals with sulfite sensitivity.

Sulfite Sensitivity: More Than a Food Allergy

For some individuals, exposure to sulfites can lead to a range of adverse reactions including wheezing, chest tightness, coughing, and even life-threatening bronchospasms, especially in people with asthma. Others may experience skin-related symptoms such as urticaria (hives) or angioedema (swelling).

Sulfite sensitivity can develop at any point in a person's life and is not routinely included in standard allergen testing in the United States. In contrast, screening panels in Europe and by the North American Contact Dermatitis Group (NACDG) include sulfites, specifically metabisulfite, in their patch test series. This omission in U.S. testing protocols raises concern, especially given the rising rates of contact dermatitis in the general population.

In fact, the American Contact Dermatitis Society (ACDS) named sulfites the "Allergen of the Year" for 2024 to highlight this exact gap in dermatologic care and encourage more comprehensive screening.

Testing Sulfites in Everyday Beverages

To better understand sulfite exposure in common consumer products, researchers are using practical tools such as sulfite test strips to analyze beverage samples. These strips react with sulfites in a drink, changing color to indicate concentration levels, usually ranging from 10 mg/L to 500 mg/L.

For example:

Wine can contain up to 350 mg/L of sulfites.
Beer generally falls in the 10–50 mg/L range.
Fruit juices and sodas may also contain sulfites, depending on the brand and preservatives used.

While not as precise as laboratory methods like the Monier-Williams distillation-titration, test strips offer an accessible and cost-effective way to estimate sulfite levels, especially for research, public health studies, and consumer awareness.

Why This Matters for Dermatology

The growing use of sulfites across industries, combined with their omission from common allergen tests, presents a challenge for dermatologists trying to diagnose unexplained cases of contact dermatitis. Patients may react to products they consume or touch regularly, yet without sulfites on the patch test panel, the true allergen may go unnoticed.

Adding sulfites to standard testing panels could improve diagnosis and treatment for many patients. Until then, healthcare professionals and consumers alike need to remain vigilant.

Moving Forward

Sulfites are everywhere, from our grocery store shelves to our medicine cabinets. For individuals with sensitivities, exposure can lead to more than just mild discomfort. It can result in serious dermatologic and respiratory reactions that affect quality of life.

Raising awareness, improving testing standards, and conducting continued research into everyday exposure will be key steps in ensuring better care, especially as we strive to provide more personalized and inclusive dermatologic treatment.

Healing More Than Skin

My Journey into Medicine

My journey into medicine was reaffirmed from a deeply personal moment, the night my father had his first stroke. I remember the fear that hung in the air and how powerless I felt watching someone I loved suffer. Amongst the things that left the biggest impact on me, however, wasn’t just the medical care he received, it was the way his doctor took time to understand our culture, our language, and fears. That moment planted a seed. It showed me how healing is not just about diagnoses and procedures, it’s about connection, empathy, and advocacy.

As I moved through my academic journey, I held onto that lesson when I faced a struggle of my own. I developed a persistent and painful skin condition that left me feeling reclusive and insecure. It was a challenging time, both physically, emotionally, and socially. But what changed everything was the care I received from my dermatologist. She saw me not just as a patient, but as a person. She treated me with compassion, listened to my concerns, and helped me feel confident in my skin again. That experience didn’t just heal my skin; it reignited my sense of self.

Dermatology quickly became the bridge between two of my deepest passions: the science of the human body and the power of restoring self-worth. I realized that the skin is so much more than just a physical barrier, it’s where we show up in the world. And when someone is battling a visible skin condition, it can affect every part of their identity. I want to be the kind of physician who sees that, who understands that, and who helps people reclaim their confidence.

That desire took root early. While in college, I volunteered with the Look Good Feel Better program, working with patients undergoing chemotherapy and radiation. I helped teach skincare techniques, but more importantly, I witnessed the strength it took to battle terminal illnesses while holding onto self-esteem. Helping patients feel empowered, comfortable, beautiful, and seen, despite the toll of treatment, was a profound reminder of how powerful dermatologic care can be.

As a medical student at Morehouse School of Medicine, I’ve had the opportunity to build on that foundation. I've worked with underserved communities and mentored other students navigating through the field of medicine. My experiences at Morehouse have reinforced what I believe to be true: medicine is about service, and dermatology is a unique space where science meets self-empowerment.

Now, as I prepare for residency, I carry all of those experiences with me the fear and hope I felt beside my father, the vulnerability of being a patient myself, and the privilege of standing alongside others in their own health journeys. These moments have shaped who I am and the kind of dermatologist I hope to become. Every person deserves to feel seen, valued, and confident and I’m committed to being a physician who helps make that possible.
