Polyglutamic Acid (PGA) is a powerful humectant, a type of peptide, that can attract and hold a large amount of water, significantly more than hyaluronic acid. It helps to keep the skin hydrated and plump.
How does Polyglutamic Acid benefit the skin?
PGA forms a hydrating film on the skin's surface, preventing moisture loss and improving skin elasticity. This leads to a smoother appearance and can reduce the visibility of fine lines.
