Gluconolactone is a polyhydroxy acid, or PHA. Like other exfoliating acids it loosens the bonds between dead skin cells, leaving skin smoother and brighter. Its larger molecules work more gradually at the surface, though, so it's generally better tolerated than glycolic acid and less likely to sting.
It also attracts water, which means it hydrates as it exfoliates. That makes it a good option for sensitive, dry or easily irritated skin, and a gentle step for anyone new to acids.
NeoStrata and its sister brand Exuviance are well known for their work with PHAs. Start with a few times a week, build to daily if your skin is happy, and wear SPF each morning.
