    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 can be used during the day.

    💬 Frequently Asked Questions
    Q What is Ascorbic Acid Glucoside (AA2G)?
    Ascorbic Acid Glucoside (AA2G) is a stable derivative of Vitamin C formed by bonding ascorbic acid with glucose. It is more stable than regular Vitamin C and is widely used in cosmetics, skincare products, and functional foods.
    Q How does AA2G help with skin brightening?
    AA2G inhibits tyrosinase activity, which reduces melanin production in the skin. This helps brighten skin tone, fade dark spots, acne marks, and post-inflammatory hyperpigmentation over time.
    Q Is AA2G suitable for sensitive skin?
    Yes. AA2G is non-irritating and has good transdermal absorption. It is suitable for all skin types, including sensitive skin, making it a preferred Vitamin C ingredient for gentle formulations.
    Q Can AA2G be used in daytime skincare products?
    Yes. Unlike some Vitamin C derivatives, AA2G is non-photosensitive, which means it does not cause photosensitivity reactions. It can be safely incorporated into daytime skincare products such as sunscreens, serums, and moisturizers.
    Q What is the purity specification of your AA2G?
    Our Ascorbic Acid Glucoside has an assay of greater than 99.5%, with free ascorbic acid and free glucose both at ≤0.1%, ensuring high purity and quality suitable for cosmetic and food-grade applications.
    Q What are the packaging and storage requirements for AA2G?
    AA2G is packaged in 20 kg cartons. It should be stored in a well-ventilated, cool, and dry place to maintain product stability and quality over its shelf life.
