Gluconolactone

Gluconolactone is a polyhydroxy acid (PHA) derived from glucose through fermentation, offering gentler exfoliation than traditional alpha hydroxy acids due to its larger molecular size. This lactone naturally chelates metal ions while providing simultaneous moisturizing benefits through its multiple hydroxyl groups. Formulators favor gluconolactone for sensitive skin formulations because it delivers effective exfoliation with minimal irritation potential compared to glycolic or lactic acid.
