Trehalose
What is Trehalose?
Trehalose is a non-reducing disaccharide made of two glucose molecules linked by a distinctive alpha-1,1-glycosidic bond, naturally produced by yeast, fungi, bacteria, plants, and desiccation-resistant organisms. In cosmetics, it appears in moisturizers, serums, cleansers, and conditioners as a humectant and skin conditioner. It works by drawing water from the environment into the skin's upper layers, sustaining hydration without stickiness. Trehalose also stabilizes proteins and enzymes in formulas, shielding them from drying out or losing activity during storage or application. This property aids in maintaining product integrity and supports skin's moisture barrier against daily environmental challenges, fostering a smoother, more resilient surface. Its biocompatibility makes it ideal for everyday routines across formulations.
