What is Polyglutamic Acid?
Polyglutamic acid (PGA) is a powerful hydrating ingredient derived from fermented soybeans (natto). Known as a “moisture magnet,” it can hold up to 4 times more water than hyaluronic acid, making it one of the most effective humectants in skincare.
Polyglutamic Acid in Skincare Formulation
In cosmetic PGA is a water-soluble peptide that enhances hydration by forming a protective film on the skin’s surface while drawing in moisture. It is often used in serums and moisturisers to improve skin plumpness, elasticity and smoothness. PGA also helps reduce the breakdown of natural hyaluronic acid in the skin, prolonging hydration.
