Retinol is the active ingredient in many over-the-counter anti-aging products and is not the same as retinoic acid. It is a form of vitamin A that's used to promote cell growth and repair, which can help your skin look more youthful. It also helps with collagen production, which helps keep your skin looking firm by strengthening it against sun damage or other factors that cause wrinkles. Retinols are available in several forms. You must also know that it is available as an ingredient in many other skincare products as well: moisturizers, serums and creams.
