Active ingredient
PHA
INCIGluconolactone
What it is
PHA (polyhydroxy acid), most often Gluconolactone, is a large-molecule exfoliating acid that refines the surface gently. Its size keeps it on the upper layers, which makes it a tolerable option for sensitive or mature skin, and it also draws in moisture.
Mechanism in detail
What PHA does
Loosens surface cell bonds slowly while binding water, so it smooths the look of texture with minimal sting.
