Gluconolactone

Because its molecules are larger than those of traditional AHAs (Alpha Hydroxy Acids), gluconolactone works primarily on the skin's surface, making it particularly well suited to sensitive skin or skin that commonly reacts to products or ingredients. 

Gluconolactone is an organic compound derived from gluconic acid, a naturally occurring substance found in honey, fruit, and the human body. In chemistry, it is classified as a polyhydroxy acid (PHA) and has a larger molecular size relative to AHAs and BHAs.

As it removes dead skin cells, gluconolactone also attracts moisture to the skin, helping to support a smooth complexion. 

This is chemical exfoliation, meaning no friction, no mechanical force, no scrubbing. That's because the acid does the work, loosening dead cells at the surface so they shed the way the skin naturally intends, just more efficiently and consistently.

Meanwhile, its antioxidant properties help defend against environmental stress, while ongoing support for the skin barrier reduces moisture loss.

Gluconolactone is a gentle exfoliant that smooths skin texture and effectively supports hydration at the level of the skin barrier.
