Ascorbyl Glucoside (AA2G)

Main Functions & Benefits

• Skin Brightening & Spot Fading: A well-established brightening ingredient that effectively inhibits tyrosinase activity and reduces melanin formation to fade dark spots, age spots and freckles, evening out and brightening overall skin tone.
• Antioxidation & Photoprotection: As a potent antioxidant, it neutralizes free radicals (e.g., reactive oxygen species induced by UV exposure), shields skin from environmental stress and photodamage, and helps prevent photoaging.
• Collagen Boosting: Stimulates collagen synthesis to preserve skin elasticity and firmness and minimize fine lines and wrinkles.
• Mild & Low Irritation: More neutral in pH and gentler than pure Vitamin C with minimal irritation, suitable for most skin types including sensitive skin.

Application Guidelines & Precautions

• Excellent Stability: Thanks to its stable molecular structure, AA2G retains its bioactivity under high temperatures and across a wide pH range of 5.0–8.0, extending the shelf life of finished products.
• Compatible Formulation: It blends well with ingredients such as niacinamide to synergistically enhance skin brightening and tone correction.
• Daily Sun Protection: Daily sunscreen application is mandatory when using AA2G-containing skincare products to maximize brightening and antioxidant efficacy.
• Safety Profile: Safe for cosmetic use at typical inclusion dosage of 2–5%, with very low incidence of skin irritation.
