Polyglutamic Acid 92

Polyglutamic Acid (PGA) is often compared with Hyaluronic Acid (HA) and both have impressive hydrating qualities. PGA is known for its stronger long lasting moisturizing properties and it can help to reduce the stickyness of hyaluronic acid. In addition Polyglutamic Acid 92 enhances skin elasticity and forms a smooth flexible film on the skin, which helps to prevent loss of water by trapping and sealing in moisture and is said to help against pollution. It's not only a great ingredient for skin care applications, but also improves the hair tensile strength and helps to reduce hair damage caused by hydrogen peroxides and other bleaching products.
