POLY GLUTAMIC ACID (liquid)

POLY GLUTAMIC ACID is a powerful biopolymer derived from fermented soybeans, known for its exceptional moisture-retention capability.
It provides superior hydration by holding up to 5,000× its weight in water—significantly more than hyaluronic acid.
It improves skin elasticity, reinforces the moisture barrier, and enhances the performance of other actives.
Ideal for hydrating serums, moisturizers, gels, masks, and hair-conditioning formulations.
