Gluconolactone, a Poly Hydroxy Acid (PHA) naturally found in the skin, offers anti-ageing and hydrating effects. With water-attracting hydroxyl groups, it conditions and moisturises the skin. Gentle yet potent, it’s suitable for sensitive or rosacea-prone skin, building the barrier and reducing redness. Caution is advised when used with glycolic acid. It preserves tissue, maintains elasticity, and smoothens texture, diminishing fine lines for a youthful appearance.
