Betaine maintains the skin's moisture balance and strengthens the skin barrier even under very dry (environmental) conditions. It is a natural osmoprotectant, i.e. an osmolyte, that protects cells from environmental stress like oxidative (UV radiation) and thermal stress (dehydration) by controlling cell water balance. 100% bio-based, betaine naturally occurs in plants and animals. The one we use in our Gentle Gel Cleanser is made from Finnish sugar beets.
