Retinoids have been used in skin care with great results for many years, in fact many of my products contain retinoids. What retinoids do is they reduce your wrinkles by speeding up your production of Vitamin A. What the vitamin A does is it slows down your breakdown of collagen and speeds up cell division. Retinoids however are not good for women who are pregnant or breast feeding, it has been shown to cause birth defects. There are many different names for Retinol so be on the look out. If you would like a great alternative try this Super Hyaluronic Acid Cream
