Stop UV rays and free radicals dead in their tracks all day, every day! Protection from the sun is absolutely critical to fighting off the aging process, especially after using powerful resurfacers that actually remove much of your skin’s natural protection. And remember, protection against UVA and UVB rays is equally as important to ward off cancer and fast-aging skin: UVB rays burn and damage the top layer of the skin, while UVA rays penetrate much deeper (without actually seeing the burn) seriously damaging collagen and resulting in wrinkled and sagging skin.
