If you’ve decided to diversify and look into some other way to hydrate your skin, you’re in the right place. Polyglutamic acid products introduce you to a new -and better- way of boosting hydration. And that’s by helping your skin retain water. The good news is there’s more. Because polyglutamic acid has some lesser-known benefits too. So if you’re on the hunt for a polyglutamic acid serum or cream, we’ve got you covered!

A buzzy ingredient but still somewhat mysterious, polyglutamic acid (PGA) is a humectant. It’s made up of a chain of amino acids called glutamic acid and it’s isolated from fermented soybeans. It attracts water and binds it to the skin. Its benefits are comparable to hyaluronic acid, collagen, and glycerin.

What sets it apart from other humectants is the fact that it’s better at keeping your skin hydrated. While a hyaluronic acid serum potentially dehydrates your skin unless you lock it in with a moisturizer, a polyglutamic acid serum stays on the surface of the skin to prevent moisture loss.

The best part is that polyglutamic acid prevents the breakdown of hyaluronic acid in your skin. It’s also often paired with hyaluronic acid in skincare products for enhanced benefits. Another unique benefit of polyglutamic acid is that, unlike other humectants that usually disappear into the skin, polyglutamic acid tends to leave a silky, satin feel on the skin.

Other benefits of it are reducing the visibility of fine lines, reducing redness and inflammation, and stimulating your skin into producing its own natural moisturizing factors. So it’s no surprise that it’s becoming the hero ingredient in more and more skincare products. Scroll down for our round-up of the best skin care products formulated with polyglutamic acid.
