Polyglutamic Acid Serum

Dry

No community rating yet.

The serum that introduced most people to polyglutamic acid, a fermented humectant that holds several times more water than hyaluronic acid. It sits slightly filmy on the surface, giving an instant glazed look that makeup artists exploit. Best layered over, not instead of, deeper hydrators.
