Gluconolactone

Gluconolactone is a water-soluble poly-hydroxy acid (PHA) derived from gluconic acid and one of the gentlest exfoliators in skincare. It does not penetrate as deeply as AHAs or BHAs but it does have additional properties, including providing hydration and mild antioxidant properties for the skin. Gluconolactone has a gentle, non-irritating formula that makes it suitable for all skin types, including sensitive skin.
