Many skin care products claim to improve skin texture, reduce fine lines and wrinkles, increase collagen, and treat acne. Many of these products work. This is due to retinoids, which are active ingredients in these products.
There are, however, different kinds of retinoids. Various retinoids are available, including retinol and tretinoin (also referred to as Retin-A). Several skin care products contain retinol and tretinoin, among other active ingredients. Choosing the right skin care product for you starts with understanding what each can do for you.
