Polyglutamic Acid for Eczema (Atopic Dermatitis)
A hydrator often pitched as "stronger than hyaluronic acid." It sits on the surface, locks water in, and helps your skin make more of its own moisturizers over time.
Why it works for Eczema (Atopic Dermatitis)
Holds a lot of water at the skin surface and helps your skin keep its own moisture longer. Polyglutamic acid (PGA) comes from fermentation and can hold about 5,000 times its weight in water, roughly 5 times more than hyaluronic acid. It forms a thin film that slows the breakdown of your skin's natural hyaluronic acid. It is a handy surface hydrator for everyday eczema care.
How Polyglutamic Acid works
Fermentation-derived poly-amino-acid that forms a water-binding film on the skin surface, upregulating natural moisturizing factor components and filaggrin in keratinocytes.
