Many people incorrectly assume dry skin leads to wrinkles and that moisturizers can prevent them. Not true. Research shows 90 percent of wrinkles are caused by the sun’s UVA light and sun damage is the #1 cause of premature aging in women and men.
Why are UVA rays so bad? Even at low-level exposures, UVA light breaks down collagen, which causes wrinkles. Even worse, scientists have found that UVA is the main culprit for many melanomas because it reaches deep into the underlying support structure of the skin.
Your options for sun protection are SPF moisturizers, basic sunscreens or tinted moisturizers.

How good is Mexoryl? “It produces a product which gives us almost perfect protection against sunshine,” said Dr. Vincent DeLeo, chairman of dermatology at Columbia University to ABC News.”
