As a film-forming humectant, PGA works on the skin surface to create a moisture-retaining network that reduces transepidermal water loss (TEWL), improves skin texture, and delivers an immediate plumping and smoothing effect. It also enhances the skin's natural moisturizing factors (NMF) and supports hyaluronic acid retention by inhibiting hyaluronidase activity.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBinds up to 5,000x its weight in water — superior to hyaluronic acid\u003c\/li\u003e\n\u003cli\u003eForms a moisture-retaining film to reduce TEWL\u003c\/li\u003e\n\u003cli\u003eImmediate plumping, smoothing, and skin-softening effect\u003c\/li\u003e\n\u003cli\u003eInhibits hyaluronidase to preserve skin’s own hyaluronic acid\u003c\/li\u003e\n\u003cli\u003eEnhances natural moisturizing factors (NMF)\u003c\/li\u003e\n\u003cli\u003eCosmetic-grade ≥90% purity biopolymer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eINCI:\u003c\/strong\u003e Polyglutamic Acid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCAS:\u003c\/strong\u003e 28829-38-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular Formula:\u003c\/strong\u003e (C₅H₇NO₂)ₙ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e \u0026gt;100,000 Da\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurity:\u003c\/strong\u003e ≥90%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAppearance:\u003c\/strong\u003e White to Off-White Powder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolubility:\u003c\/strong\u003e Water Soluble\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade:\u003c\/strong\u003e Cosmetic Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e 0.1–1.0%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e Water Phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Sizes:\u003c\/strong\u003e 10g | 20g | 50g | 100g\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDisclaimer\u003c\/h3\u003e\u003cp\u003eThis ingredient is intended for cosmetic use only.
