One of the most effective ways to keep skin looking its best is using daily sun protection. UV (ultra violet) rays from the sun cause premature aging by creating free radicals, which are unstable molecules that break down collagen in the skin. Over time, UV exposure and free radicals lead to premature aging.
There are two types of UV rays that breach the ozone layer and cause damage to the skin: UVA rays and UVB rays. UVA rays penetrate the layers of the skin, causing most premature aging. UVB rays cause tanning and burning on the upper layers of the skin. Both UVA and UVB rays are linked with skin cancer and long-term harm for your health. Adding sunscreen to your daily skincare ritual, as well as being mindful of sun exposure, helps defend skin against from both types of UV rays. It’s never too late to begin protecting your sun and researching information about the active ingredients to determine which sunscreen is best for your skin and lifestyle.
