Taurine description

Taurine is a non-essential (meaning the body can make it so it need not be obtained from food) amino acid that is found naturally in skin. One of its functions is to help the body maintain homeostasis, the state of balance among all internal systems the body needs to work correctly. Studies point to a decline in taurine content over time as a contributing factor to the development of wrinkles and water loss in skin. Research also shows that because of taurine’s antioxidant abilities, topical application can help restore skin’s youthful appearance by improving the look of wrinkles. It can also help restore skin’s vital moisture barrier. Usage levels of taurine in skin care range from 0.1–1%. It is supplied as a white powder. Note that taurine may also appear on an ingredient list as oxothiazolidine.
