What Is Anhydroxylitol?
Anhydroxylitol is a carbohydrate derivative—a sugar alcohol with water-binding properties. It functions as a humectant, meaning it draws moisture from the environment into the skin and helps the stratum corneum (the skin's outer layer) retain that hydration. It's used in skincare products at relatively modest concentrations to support skin hydration and conditioning.
This ingredient belongs to a family of saccharide derivatives that have been studied for their moisturising behaviour. It appears in a small proportion of skincare formulations, often in hydrogel or aqueous bases where its water-attracting properties can work effectively.
Benefits for Your Skin
How It Works
Anhydroxylitol works by attracting water molecules to the stratum corneum through hydrogen bonding. Once applied to skin, it draws moisture both from the environment and from deeper skin layers, then holds onto it, preventing evaporation. This mechanism helps maintain skin hydration, which in turn can reduce dryness and improve skin texture.
The ingredient is particularly effective when used in formulations designed to hold and deliver moisture, such as hydrogels or lightweight lotions where water availability supports its humectant function.
Clinical Evidence & References
Limited clinical data is available specifically on anhydroxylitol in isolation. However, research examining carbohydrate-derived moisturising compounds (including anhydroxylitol formulated in hydrogels) has measured improvements in stratum corneum hydration using electrical conductivity methods. These studies suggest the ingredient contributes measurably to skin moisturisation when incorporated into well-designed formulations.
A safety review by the Expert Panel for Cosmetic Ingredient Safety concluded that anhydroxylitol is safe for cosmetic use at current concentrations. More targeted research would help clarify its individual efficacy compared to other humectants.

How to Use
Anhydroxylitol works most effectively in hydrating serums, lightweight gels, and moisturisers applied to damp skin. Since it's a humectant, applying your product to freshly cleansed, slightly damp skin can enhance its water-binding capacity. It pairs well with occlusive ingredients (like oils or butters) in layered routines, where the humectant draws moisture in and the occlusive seals it.
