Polyglutamic Acid

What is Polyglutamic Acid?

Polyglutamic acid is the hydration heavyweight champion—a fermented peptide derived from soybeans that can hold up to four times more moisture than hyaluronic acid. This large molecule forms a breathable film on the skin's surface, sealing in hydration while preventing water loss. Think of it as an invisible moisture-locking shield that simultaneously attracts more water from the atmosphere. It's the skincare equivalent of a high-efficiency water reservoir—capable of holding extraordinary amounts of moisture while slowly releasing it as your skin needs hydration. For severely dehydrated or mature skin seeking dramatic plumping effects, polyglutamic acid offers that perfect combination of powerful surface hydration and moisture-retention properties that creates visibly plumper, dewier skin with both immediate and cumulative benefits when used consistently.
