Its silky, non-greasy texture layers easily under moisturizers or makeup, helping skin look softer with reduced appearance of fine lines while promoting a more even, luminous tone.\u003c\/p\u003e\n\n\u003ch3\u003eHow does polyglutamic acid hydrate skin differently than hyaluronic acid?\u003c\/h3\u003e\n\u003cp\u003ePolyglutamic acid (PGA) binds water at the skin surface and can hold more moisture per molecule than hyaluronic acid, making it especially effective for visible, immediate surface hydration.
