The Science of Polyglutamic Acid

Composed of gamma-glutamic acid polymers that bind and retain moisture on the skin’s surface
Inhibits hyaluronidase enzyme, slowing hyaluronic acid degradation for prolonged hydration
Promotes natural moisturizing factor (NMF) synthesis to strengthen barrier function
Improves skin radiance and plumpness through enhanced water retention and smoothness

It forms a lightweight film on the skin to prevent water loss and enhance hydration retention.

It sits on the surface to lock in moisture, while hyaluronic acid draws water deeper into the skin.

Improved hydration, smoother texture, enhanced elasticity, and better performance of other actives.

Yes, especially beneficial for dry, dehydrated, or sensitive skin.

Yes, it helps strengthen the outer layer by increasing hydration and supporting lipid structure.
