About Gluconolactone

Gluconolactone (PHA) is a polyhydroxy acid derived from glucose oxidation, widely used in skincare for its gentle exfoliating, hydrating, and antioxidant effects. It's considered a suitable alternative to AHAs, especially for sensitive skin. While generally safe, mild skin irritation and increased sun sensitivity are potential side effects. It is also used as a food additive functioning as a sequestrant, acidulant and leavening agent. Oral consumption dosages for specific health benefits are not well-defined, but topical application is common in varying concentrations depending on the product formulation.
