Gluconolactone

Description

Gluconolactone is a polyhydroxy acid (PHA) that has gained significant attention in the skincare industry for its multifaceted benefits. This gentle exfoliant is derived from gluconic acid, a naturally occurring substance found in fruits, honey, and wine. Unlike alpha-hydroxy acids (AHAs), gluconolactone has a larger molecular structure, allowing for slower penetration and reduced irritation, making it suitable for sensitive skin types.

As a humectant, gluconolactone attracts and retains moisture, promoting skin hydration and improving barrier function. Its antioxidant properties help neutralize free radicals, protecting the skin from environmental stressors and premature aging. Gluconolactone also exhibits chelating abilities, which can help reduce the negative effects of metal ions on the skin.

In skincare formulations, gluconolactone is typically used at concentrations between 3% and 15%. It can enhance the efficacy of other active ingredients and has been shown to improve skin texture, reduce fine lines, and promote a more even skin tone. Additionally, gluconolactone has antimicrobial properties, potentially benefiting acne-prone skin. Its gentle nature and multiple benefits make it a versatile ingredient suitable for various skincare products, from cleansers to serums and moisturizers.
