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.
⭐
Key Features: More stable than ordinary Vitamin C — non-irritating, good transdermal absorption, non-photosensitive and safe for daytime use.

Frequently Asked Questions (FAQ)
Q
What is Ascorbic Acid Glucoside (AA2G)?Ascorbic Acid Glucoside (AA2G) is a stable glycoside derivative of Vitamin C. It is enzymatically synthesized by bonding glucose to Vitamin C, resulting in a compound that is significantly more stable than free ascorbic acid and suitable for use in cosmetics, skincare, and functional food products.
Q
How does AA2G differ from regular Vitamin C?Unlike ordinary Vitamin C (L-Ascorbic Acid), AA2G is highly stable and resistant to oxidation. It does not cause skin irritation, is non-photosensitive (safe for daytime use), and offers superior transdermal absorption. Once absorbed by the skin, enzymes convert AA2G back into active Vitamin C to deliver its full benefits.
Q
What are the main benefits of AA2G in skincare?AA2G inhibits tyrosinase activity to reduce melanin production, helping to brighten skin tone and 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 helps control excess oil — making it suitable for all skin types, including sensitive skin.
Q
What types of products is AA2G commonly added to?AA2G is widely used in whitening serums, creams, face masks, sunscreens, and men's oil-control products. In the functional food sector, it is incorporated into drinks, tablets, solid beverages, whitening supplements, and collagen-based oral beauty products.
Q
What is the recommended storage condition for AA2G?AA2G should be stored in a well-ventilated, cool, and dry place, away from direct sunlight and moisture. Proper storage conditions help maintain the product's purity and extend its shelf life.
Q
What is the standard packaging specification for AA2G?AA2G is packaged in 20 kg per carton. This standard packaging is designed for safe transport and storage while maintaining product integrity. Custom packaging arrangements may be available upon request for large-volume orders.
