Polyglucuronic Acid

What Polyglucuronic Acid is & what it does

Polyglucuronic Acid is a polysaccharide built from glucuronic acid units, the same sugar acid found in the backbone of hyaluronic acid. In skincare it is used chiefly as a humectant and film-forming hydrator, drawing in water and leaving a light moisturizing layer on the skin surface. It is often marketed as a lightweight alternative to larger hyaluronic-acid molecules because of its smaller size. It is generally regarded as gentle and is found in serums, gels, and moisturizers.
