About this ingredient

Gluconolactone is a polyhydroxy acid (PHA) derived from glucose that functions as a gentle exfoliant and humectant in skincare formulations. It provides chemical exfoliation with lower irritation potential than AHAs or BHAs, while also hydrating the skin and supporting the skin barrier. It is particularly suitable for sensitive skin types due to its larger molecular size and milder action.
