This one is a real heavy-hitter where skin health is concerned. It’s a particularly good treatment for aging skin, since it helps to reduce wrinkles, reduce the appearance of age spots and smooth out areas that may have become rough. Vitamin A is found in many creams due this vitamin’s derivatives which are called retinoids. More than 700 research studies have shown the benefits of retinoids for skin health.
