Polyglutamic Acid (PGA)

Polyglutamic Acid (PGA) is a high-performance, water-soluble biopolymer and powerful humectant designed to boost hydration and moisture retention in cosmetic formulations.

PGA forms a lightweight moisture-binding film on the skin, helping to reduce moisture loss while leaving skin looking plumper, smoother and more radiant. It is an exciting addition to modern hydrating, barrier-support and anti-ageing formulations.
