Appearing as a white to off-white powder, high-performance γ-PGA is a bio-engineered, non-animal moisturizer derived from natto fermentation, specifically developed for premium skincare formulations to deliver deep, long-lasting hydration with a refreshing, non-sticky skin feel. As a high-performance polymer, our γ-PGA is an ideal alternative to conventional hyaluronic acid and other polysaccharide-based humectants, offering superior water-holding capacity (up to 5,000× its own weight), enhanced penetration, and multifunctional benefits including collagen support and hyaluronic acid preservation.

High-performance γ-PGA (Gamma-Polyglutamic Acid) is a bio-engineered, nature-derived moisturizer produced through natto fermentation, offering exceptional hydration and skin compatibility for modern cosmetic formulations. Compared with conventional polysaccharide-based humectants or animal-derived collagen, our γ-PGA features a unique amino-acid backbone, an extraordinary water-absorption capacity (up to 5,000× its own weight), and a refreshing, non-sticky film-forming property, delivering deeper penetration, prolonged moisture retention, and enhanced barrier support. γ-PGA can penetrate the stratum corneum to reinforce the skin’s Natural Moisturizing Factors (NMF), inhibit hyaluronidase to stabilize endogenous hyaluronic acid, and stimulate fibroblast activity for collagen synthesis, making it a multifunctional, sustainable, and consumer-preferred moisturizer for premium skincare regimens.
