Saccharide Isomerate

Saccharide Isomerate is a gentle, plant-derived humectant that helps skin attract and hold on to moisture. Often described as a ‘water magnet’, it delivers long-lasting hydration without feeling sticky. You’ll find it in many UK moisturisers, serums and masks as a kinder alternative to some synthetic humectants.

How it works in skincare

In skincare formulations Saccharide Isomerate works by binding water molecules to the surface of the skin and within the upper layers of the stratum corneum. Its unique molecular structure allows it to remain effective even in low-humidity environments, providing continuous hydration for up to 72 hours. It is valued by British cosmetic chemists for its non-irritating profile and ability to improve the sensory feel of lightweight emulsions and gel textures.
