Humectant

Gluconolactone is a humectant that attracts and binds water to the skin, providing hydration. It also acts as a mild exfoliant for smoother skin texture.

Gluconolactone acts as a humectant by drawing moisture from the surrounding environment and binding it to the skin. This process helps to hydrate the stratum corneum, the outermost layer of the skin, improving its moisture content and reducing dryness, flakiness, and roughness. It also functions as a mild exfoliant due to its polyhydroxy acid (PHA) nature, gently removing dead skin cells and promoting smoother skin texture.
