What Is It?
The most stable Vitamin C derivative available. AA2G is formed by bonding Ascorbic Acid with glucose, creating an incredibly stable molecule that resists oxidation under virtually all conditions. The tradeoff is lower bioavailability, requiring enzymatic cleavage by skin glucosidases.
🔬 The Science
The glucose moiety protects the ascorbic acid molecule from oxidation completely. Skin glucosidases slowly cleave the glucose bond over time, releasing LAA gradually. This sustained-release effect makes it excellent for long-term glow maintenance.
⚗️ Stability Note
Essentially oxidation-proof. No color change or degradation even over prolonged shelf life.
