Ascorbyl Glucoside
Ascorbyl Glucoside is a stable, water-soluble form of vitamin C commonly used in UK skincare products. It is gentler than pure ascorbic acid, making it suitable for daily use without causing irritation for most skin types. Shoppers often choose it for its brightening and antioxidant properties in serums, creams and essences.
How it works in skincare
In cosmetics and skincare, ascorbyl glucoside functions as a precursor to vitamin C that converts gradually to ascorbic acid once absorbed by the skin. This slow-release mechanism helps it deliver antioxidant protection while remaining stable in both water-based and emulsion formulas, resisting oxidation far better than L-ascorbic acid. It is frequently included in brightening serums, moisturisers and eye creams to support a more even complexion and defend against environmental stressors.
