Description
Polyglutamic Acid is a notable high-molecular-weight natural amino acid polymer, often praised for its superior skin-hydrating properties, potentially even surpassing well-known Hyaluronic Acid. This potent humectant acts by forming a protective film on the skin surface. This film not only draws environmental moisture to the skin, but also significantly enhances the skin capacity to bind and retain that moisture. As a result, Polyglutamic Acid contributes to a plumper, smoother, and more supple complexion, effectively combating dryness and improving overall skin texture and elasticity. Its large molecular size ensures it remains on the skin, providing long-lasting hydration.
