Application

Ascorbic Acid Glucoside (AA2G) is a stable derivative of Vitamin C, mainly applied in cosmetics and skincare products, with a small amount used in functional foods.

1. Cosmetics & Skincare (Main Application)

It inhibits tyrosinase to reduce melanin production, brighten skin tone, fade dark spots, acne marks and post-inflammatory hyperpigmentation. It also scavenges free radicals, resists photoaging, promotes collagen synthesis, improves skin elasticity, refines pores and controls oil, suitable for all skin types including sensitive skin. It is widely added to whitening serums, creams, masks, sunscreens and men's oil-control products.

2. Other Applications

As a stable Vitamin C, it is used in functional drinks, tablets, solid beverages and oral beauty products (such as whitening pills, collagen drinks), with better stability than ordinary Vitamin C.

Frequently Asked Questions (FAQ)

What is Ascorbic Acid Glucoside (AA2G)?

Ascorbic Acid Glucoside (AA2G) is a natural, highly stable derivative of Vitamin C. It is primarily used in cosmetic formulations and skincare products for brightening and anti-aging, as well as in functional food products.

How does AA2G benefit skincare formulations?

AA2G inhibits tyrosinase activity to reduce melanin production, effectively fading dark spots, hyperpigmentation, and acne marks. It scavenges free radicals, promotes collagen synthesis, improves skin elasticity, refines pores, and provides photoaging defense.

Is Ascorbic Acid Glucoside suitable for sensitive skin?

Yes, unlike traditional L-ascorbic acid, AA2G is non-irritating, gentle, and non-photosensitive, making it safe for all skin types including sensitive skin and suitable for daytime use.

Why is AA2G preferred over standard Vitamin C?

Standard Vitamin C degrades quickly in heat, light, and water. AA2G exhibits significantly higher stability in formulation, excellent water solubility, and breaks down gradually into active Vitamin C within the skin via natural enzymes.

What are the standard packaging and storage recommendations?

The standard commercial packaging is 20kg per carton. It should be stored sealed in a cool, dry, and well-ventilated area away from direct moisture and ambient heat.
