What are the benefits of Polyglutamic acid for the skin?

Polyglutamic acid (PGA) is a synthetic peptide that is water soluble, edible and environmentally friendly. It consists of glutamic acid molecules. It is widely used in medicine, food, cosmetics and other fields. In skin care products, PGA is used as a highly effective humectant that adsorbs moisture and seals it into the skin. Compared with hyaluronic acid, a humectant with similar properties, the water locking effect is more significant. This may be due to the fact that it forms a protective film on the skin's surface, which helps prevent water evaporation, protects the skin's natural hydration and locks it in.

Polyglutamic acid (PGA) is often sold as a serum and can also be added to cosmetic products such as creams, lotions, masks, toners and foundations.Polyglutamic acid serums not only act as a highly moisturising agent, but they also help to reduce the signs of wrinkles and fine lines, making the skin more resilient and radiant. In addition, PGA is a good and beneficial alternative for people with hyaluronic acid allergies.
