Gluconolactone (5.5%)
Gluconolactone (5.5%) is a gentle, next-generation PHA (polyhydroxy acid) that works as both a mild exfoliant and a powerful humectant. It helps renew the skin’s surface while attracting and holding moisture, making it ideal for those who find traditional AHAs too harsh. At 5.5% it delivers visible smoothing and brightening with minimal irritation.
How it works in skincare
In skincare and cosmetic formulations, gluconolactone functions as a PHA that gently exfoliates by loosening the bonds between dead skin cells, revealing fresher, smoother skin beneath. Its large molecular size prevents deep penetration, reducing the risk of irritation while still improving skin texture and clarity. It also acts as a humectant and antioxidant, helping to strengthen the skin barrier, bind moisture, and protect against environmental free-radical damage.
