Ascorbyl glucoside is a stable form of vitamin C bound to glucose. The glucose is derived from natural starch sources such as rice, while the vitamin C is synthesized. When properly formulated and absorbed into the skin, it breaks down into ascorbic acid, also known as pure vitamin C. This gradual breakdown creates a reservoir effect on the skin, extending the duration of its benefits.

V2G (Ascorbyl Glucoside) is a whitening ingredient approved by the Ministry of Food and Drug Safety and is a stabilized vitamin C derivative. It offers greater stability compared to general vitamin C derivatives and complies with the Japanese Quasi-Drug Standard.
