Sun damage is the main external cause of aging. About 80-85% of aging is caused by the sun. The UV rays of the sun reach the skin in two different forms, as UVB and UVA rays. UVB rays cause tanning of the skin and damage the skin’s melanin when large doses are allowed to penetrate the skin. These rays cause cancer. Penetrating further into the skin are the UVA rays. These rays weaken the skin’s collagen and elastin fibers, causing wrinkling and sagging in the tissues. Though these fibers naturally weaken as we age, it happens at a much faster rate when exposed to UVA rays. Sun damage leads not only to skin cancer, aging, and collagen and elastin deterioration, but to hyperpigmentation, capillary damage and free radical damage.
Avoiding the sun and wearing sunscreen is the best protection for skin. Sunscreens absorb or reflect UV rays. SPF refers to the sun protection factor in sunscreens. The higher the SPF, the more protection you’ll receive from the sun. Be sure the sunscreen has full spectrum protection (protects the skin from both UVA and UVB rays).
Sunscreen can be found in the form of a moisturizer and may come in various weights and formulas suitable for various skin types. Everyone needs to wear sunscreen! My recommendation is to wear an SPF of 30 everyday, rain or shine!
Love your skin.
