2-O-β-D-Glucopyranosyl-L-ascorbic acid CAS NO.562043-82-7

2-O-β-D-Glucopyranosyl-L-ascorbic acid (AA-2G) is a highly stable, water-soluble vitamin C derivative engineered to overcome the notorious instability of pure L-ascorbic acid. By conjugating glucose at the C-2 position, this molecule exhibits exceptional resistance to oxidation, heat, and light, ensuring long-lasting potency in formulations ranging from serums and creams to functional foods. It is designed for individuals seeking effective antioxidant protection, skin brightening, and anti-aging benefits without the irritation or rapid degradation associated with traditional vitamin C, making it a preferred ingredient for sensitive skin types and long-shelf-life products.

1.MECHANISM OF ACTION

The efficacy of AA-2G hinges on its prodrug mechanism; it remains inert until it penetrates the skin or is metabolized internally, where endogenous α-glucosidase enzymes cleave the glucose moiety to release pure, active vitamin C. This controlled, time-release system ensures a sustained supply of ascorbic acid, which then functions as a potent free radical scavenger, inhibits tyrosinase to block melanin production, and serves as an essential cofactor for collagen synthesis. By modulating the Nrf2 pathway and glutathione balance, it enhances cellular antioxidant defenses, providing protection against UV-induced damage and oxidative stress at a molecular level.

2.PRODUCT INDICATIONS

This ingredient is primarily indicated for cosmetic and nutraceutical applications targeting skin rejuvenation and systemic health. In skincare, it is formulated for brightening products aimed at reducing hyperpigmentation, age spots, and melasma, as well as anti-aging regimens to improve skin elasticity and reduce fine lines. As a dietary supplement, it supports immune function and overall antioxidant status. It is particularly suitable for formulators developing stable water-based products and for consumers with sensitive skin who are intolerant to acidic forms of vitamin C.

3.CLINICAL EFFICACY OF PRODUCT

Clinical and preclinical studies demonstrate that AA-2G significantly increases vitamin C levels in the skin and plasma, leading to measurable improvements in skin tone evenness and luminosity. Research confirms its ability to reduce UV-induced erythema and protect against photoaging by suppressing collagen degradation. Beyond dermatology, studies highlight its role in mitigating neuroinflammation and extending lifespan in model organisms via gut microbiota modulation and insulin signaling pathways, underscoring its potential as a multi-functional ingredient for both topical vitality and internal wellness.
