Is gluconolactone suitable for sensitive skin?

Yes, gluconolactone is generally considered suitable for sensitive skin types due to its larger molecular size, which allows for slower and gentler penetration compared to other exfoliating acids like AHAs.

Does gluconolactone increase sun sensitivity?

Unlike some other exfoliating acids, gluconolactone is not known to significantly increase sun sensitivity. However, daily sunscreen use is always recommended as a general skincare practice.

Gluconolactone

Gluconolactone is a polyhydroxy acid (PHA) that offers gentle exfoliation and significant hydrating benefits. Its larger molecular size compared to AHAs means it penetrates the skin more slowly, resulting in less irritation. It also functions as an antioxidant and helps strengthen the skin's barrier.
