Hyaluronic Acid Vs. Polyglutamic Acid - Which Is Right For You?
Both hyaluronic acid and polyglutamic acid offer immediate and noticeable skin hydration but polyglutamic acid can further improve dry skin by aiding in the skin’s natural production of NMF. Polyglutamic acid and hyaluronic acid can even be used together or layered for further hydration and skin plumping as neither of these materials has known compatibility issues.
