Ascorbyl Glucoside
What is Ascorbyl Glucoside?
Ascorbyl glucoside is a synthetic ester of ascorbic acid (vitamin C) and glucose, forming a stable, water-soluble compound known chemically as 2-O-alpha-D-glucopyranosyl-L-ascorbic acid. Developed to overcome the instability of pure vitamin C in formulations, it remains effective at neutral pH levels without degrading quickly from light or air exposure. Primarily used in skincare serums, creams, and toners within anti-aging and brightening product categories, it functions as a pro-vitamin that skin enzymes gradually convert into active ascorbic acid. This controlled release supports its role in cosmetic applications, enhancing product shelf life while providing targeted skin benefits through topical delivery.
