Definition: It is a PHA that derives from Gluconic Acid. Just like other ingredients that are from its family, this exfoliant is safer than AHAs and more tolerated by sensitive skin.
If you are already using other type of chemical exfoliants it is an excellent product to have in a cleanser as it can be used daily or even better in a moisturiser.
