Tanning can cause irreversible damage to the DNA in your skin cells. A tan is visible evidence of damaged DNA and, contrary to popular opinion, is not a sign of good health. The damage that takes place when you expose yourself to harmful UV can lead to premature signs of aging and skin cancer.
Tanning increases your overall risk of basal cell carcinoma, squamous cell carcinoma, and melanoma. The best thing that you can do for your skin and health is to avoid tanning entirely!
What causes tanning?
Tanning is caused by over-exposure to harmful ultraviolet, or UV, radiation from the sun or artificial sources. This exposure causes damage to the cells on your outermost layer of skin, the epidermis. The skin tries to prevent further injury by producing melanin (the pigment that gives our skin its color). This results in darkening of the skin.
Tanning damages skin of all types. Even if you have a darker complexion, tanning causes injury to DNA in skin cells that can lead to premature aging and skin cancer.
