AA2G(Ascorbic acid 2-glucoside)

What is AA2G? (Ascorbic acid 2-glucoside)

AA2G, short for Ascorbic Acid 2-Glucoside, is a stable derivative of Vitamin C. It is formed by combining one molecule of L-Ascorbic Acid (pure Vitamin C) with one molecule of glucose through an enzymatic reaction. This modification greatly enhances its stability while retaining the skincare benefits of Vitamin C.

Applications:

1. Stable Skin Brightening
   • Inhibits tyrosinase activity via enzymatic hydrolysis → Gradually releases active Vitamin C → Visibly reduces dark spots, acne scars & UV-induced pigmentation.
   • Advantage: 3x higher stability vs. L-Ascorbic Acid → Maintains ≥95% potency after 24-month storage.
2. Potent Antioxidant Protection
   • Neutralizes free radicals (PM2.5/UV ROS) → Reduces oxidative stress by 42% (28-day clinical study).
   • Prevents collagen degradation → Minimizes wrinkle formation.
3. Collagen Boosting
   • Stimulates fibroblast activity → Increases Type I/III collagen density by 30% → Improves skin elasticity & pore appearance.
4. Soothing & Hydrating
   • Lowers IL-6 inflammation markers → Calms redness/irritation.
   • Enhances skin barrier function → 18% reduction in TEWL (Transepidermal Water Loss).

Fuctions:

Product Type	Dosage	Synergistic Actives
Whitening Serums	2-5%	Niacinamide (transfer blocker) + Arbutin (synthesis inhibitor)
Anti-Aging Creams	1-3%	Vitamin E (antioxidant booster) + Hyaluronic Acid (humectant)
Sunscreen/BB Cream	0.5-2%	Avobenzone (UVB filter) + Ectoin (photo-repair)
Sheet Masks	3-8%	Centella Asiatica (healing) + Peptides (penetration enhancer)

• ✅ Whitening and brightening serums

• ✅ Day creams, night creams, and moisturizers

• ✅ Anti-aging skin care products

• ✅ Sunscreens (as an antioxidant booster)

• ✅ Facial masks, eye creams, exfoliating treatments

• ✅ Functional cleansers and toners

Nutraceuticals

• Beauty Supplements: As Vitamin C precursor (50-100mg/day) → Enhances bioavailability in collagen drinks/whitening capsules.

• Functional Foods: Antioxidant stabilizer in juices/meal replacements (e.g., paired with Acerola extract).
