Ascorbyl Glucoside is a stable and water-soluble derivative of vitamin C that, unlike pure ascorbic acid, is more stable and less likely to oxidize. This helps maintain its efficacy in formulations over time. When applied to the skin, ascorbyl glucoside is gradually converted into active vitamin C. This slow-release mechanism allows it to deliver the benefits of vitamin C, such as improving skin tone and providing antioxidant protection, without the irritation that may accompany pure vitamin C.
