It's a very effective humectant that can grab onto water and keep skin hydrated.
Polyglutamic acid helps seal the moisture in your skin, and enhances the skin’s elasticity.

Unlike Hyaluronic Acid, polyglutamic acid doesn't occur naturally in our bodies. Ingredient suppliers claim it can hold 10 times more water than hyaluronic acid, which is very impressive.
