Polyglutamic Acid Powder Deep Hydration & Skin Barrier Support

High-Purity Polyglutamic Acid Functional Ingredient

Polyglutamic Acid (PGA) is a high-efficiency, naturally derived functional ingredient recognized for its exceptional moisturizing properties and skin barrier enhancement. As a biodegradable, water-soluble polymer, PGA forms a protective film on the skin surface, effectively locking in moisture, improving hydration retention, and supporting overall skin health.

Widely applied in cosmetic formulations, personal care products, functional foods, dietary supplements, and pharmaceuticals, Polyglutamic Acid delivers superior moisture retention compared to conventional humectants. It promotes skin elasticity, soothes dryness, and strengthens the skin barrier, making it a preferred ingredient in high-performance anti-aging, hydating, and barrier-reinforcing products.

Our Polyglutamic Acid is produced with advanced fermentation and purification technologies, ensuring high purity, low impurity content, and excellent consistency for global B2B clients. It is ideal for formulators, brand owners, and wholesalers seeking reliable, effective, and safe moisturizing and skin-protective ingredients.
