Gluconolactone (Gluconolactone)

Gluconolactone is a gentle, water-soluble polyhydroxy acid (PHA) valued for delivering mild exfoliation while supporting hydration and skin comfort. It gradually hydrolyzes to gluconic acid, helping to refine the look of texture and dullness with a typically lower irritation potential than many traditional alpha hydroxy acids. Thanks to its humectant character, it can enhance moisture retention and contribute to a smoother, more supple feel, making it especially suitable for sensitive-looking or dryness-prone skin types. Gluconolactone is commonly used in leave-on serums, toners, creams, and peel-like treatments, as well as in body care and scalp products where a soft resurfacing effect is desired. It is also frequently leveraged in preservation-supporting concepts and is formulated with attention to pH and overall system compatibility to maintain performance and stability.
