When this layer of film is sweating, washing hands or taking a bath, a small amount of collagen or hyaluronic acid on the skin surface is easily washed away by water, and the composition and function of this film are completely lost. If there is no follow-up skin care Assist, there is no result of improving the skin texture. However, γ-PGA or its hydrogel has an absolute advantage in price. It can be added to the basic formula in a higher amount. When applied to skin care products such as shower gel, polyglutamic acid or its hydrogel will not be completely affected. The water is rinsed off, and the residual γ-PGA film not only promotes the increase of the water content of the stratum corneum, but also the content of natural moisturizing factors in the skin can continue to increase. Even if there is no additional follow-up skin care assistance, the result is that the skin is still improved. Quality function. All in all, γ-PGA or its water glue will form a thin film when applied to the skin, which feels very good, and has the unique smoothness of γ-PGA, and it is not easy to be washed off by water. It is collagen and transparent. What's not available in acid.
