Your body needs sunlight to produce vitamin D for strong bones and teeth, but when ultraviolet rays meet unprotected skin, they can cause hyperpigmentation, sunburn, wrinkles, freckles, age spots and other damage from free radicals. Windburn adds to the damage when UV ray exposure occurs in conjunction with wind friction and your skin’s decreased moisture from the cold air. The importance of protecting your skin from exposure to the elements goes beyond the surface. UVB rays affect the outer layer of the skin and is primarily responsible for sunburns.
UVA penetrates deeper and is now believed to be a major contributor to skin damage. UV radiation is known to be a factor in the creation of free radicals which causes oxidative stress in your body and potentially, long term health issues. Besides covering up and staying out of the sun (which none of us explorers wants to do), using sunscreen is your first line of defence! Of equal importance is following exposure with skin care products that contain antioxidants – free radical scavengers – and do not contain chemicals that can cause further damage.
