What It Is

Next-generation exfoliants larger than AHAs — the gentlest chemical exfoliants available. Only remove outermost cells without deeper penetration. Ideal for sensitive, reactive, rosacea-prone or post-procedure skin. Gluconolactone also has antioxidant and chelating properties; lactobionic acid is a powerful humectant. PHAs are safe with most other actives.

Typical Effective Concentration

3–10%

At these concentrations this ingredient should appear above the 1% line on the INCI list. If you see it listed after preservatives or fragrance allergens, the dose is likely too low to work as marketed.

How to Use

PM or AM toner/serum 3–10%, can be used daily. Suitable for skin too sensitive for AHAs or BHAs.
