γ - PGA is the main component of natto viscose colloid, which can promote mineral absorption. Japan has listed γ - PGA in the list of health care ingredients for promoting mineral absorption. The special molecular structure of γ - PGA makes it have strong moisturizing ability. Adding γ - PGA in cosmetics or maintenance products can effectively increase the moisturizing ability of skin and promote skin health. Compared with hyaluronic acid (HA), which is recognized as the most moisturizing agent, the moisturizing effect of γ - PGA is 2-3 times more than that of HA, which is a new generation of biological technology moisturizing ingredients.
