How does tanning affect my skin?

A tan is visible proof that your skin is being damaged. Melanin can only protect your skin so much. If you continue to be exposed to the sun, the UV radiation can eventually damage your skin. That damage shows up as:

  • wrinkles
  • brown age spots
  • blotchiness
  • leathery, sagging skin that looks older than it is
  • In the worst-case scenario, too much sun can cause skin cancer.

Protecting yourself

The best way to care for your skin is to find a balance between activity and protection. Sunscreens can be one of your best defenses. Here are some tips to protect your skin from sun damage and reduce your risk of skin cancer.
  • Wear sunscreen with a sun protection factor (SPF) of at least 15 on an everyday basis. If you'll be in the direct sun, wear a sunscreen with a higher SPF, like 30.
  • Use broad-spectrum sunscreen that blocks both UVA and UVB rays.
  • Apply sunscreen thickly enough to make a difference.
  • If you are going to be outside for a while, reapply sunscreen every two to three hours and after swimming or sweating.
  • The sun's rays are strongest between 10 a.m. and 4 p.m., so take frequent breaks during these hours.
  • Wear a hat with a brim and sunglasses that provide almost 100% protection against ultraviolet radiation.
