Betaine occurs naturally in our own body including skin and hair. The skin cells accumulate betaine actively during the dehydration and UV-radiation. Betaine is called an osmoprotectant as it controls the right water balance of the cell without interfering with normal cellular processes. It can also counteract chemical and mechanical skin irritants. Facilitates fibroblast growth collagen production and works in synergy with glycerine to increase hydration in the skin.
