AA2G (INCI: Ascorbyl Glucoside) is a stabilized Vitamin C derivative — L-Ascorbic Acid 2-Glucoside — produced through enzymatic technology by Nagase. Unlike pure Vitamin C, AA2G is gradually metabolized in the skin into Vitamin C and glucose via naturally occurring alpha-glucosidase, providing a sustained, time-released supply of active Vitamin C.

This ingredient delivers multiple skin benefits including melanin inhibition, age spot lightening, collagen and hyaluronic acid synthesis support, UV damage reduction, and antioxidant protection. Its excellent formulation stability across various pH levels minimizes discoloration and degradation risk during manufacturing and storage compared to other Vitamin C derivatives.

Approved as a quasi-drug active in Japan for pigmentation claims, COSMOS approved, Halal certified, and China IECIC listed, AA2G is a globally trusted brightening and anti-aging ingredient for skin care and sun care product lines.
