AA2G Introduction

AA2G (Ascorbic Acid 2-Glucoside), also known as ascorbyl glucoside, is one of the derivatives of vitamin C. It retains the full biological activity of vitamin C; moreover, it is more stable than VC, and it’s recognized as the most stable derivative of vitamin C. AA2G is recognized as one of whitening additives by Department of Health. It not only inhibits the activity of tyrosinase to reduce the formation of melanin, but also reduces melanin, alleviates the formed melanin, reduces pigmentation. Therefore, AA2G can whiten and brighten skin. AA2G also promotes the synthesis of collagen, improves skin wrinkles and rough dry skin. As a highly effective whitening agent, AA2G has already emerged in the cosmetics market for a long time. It’s added to cosmetics of many well-known brands at home and abroad, such as Lancome, SK-II, Keyan, Clinique, etc.

Vitamin C vs AA2G (Ascorbic Acid 2-Glucoside)



AA2G (Ascorbic Acid 2-Glucoside)

Molecular Formula



Molecular Structure

The hydroxyl group on the C=C double bond of vitamin C molecular structure is very unstable, so VC is easily decomposed in aqueous solution. However, AA2G has a glycosidic bond in its molecular structure, which is not easily decomposed and very stable.


Low stability, easy to be oxidized, easy to break down in light.

Good light and heat stability, not easy to decompose


Both of them have the same biological activity to inhibit melanin formation, reduce melanin, scavenge free radicals in the body, promote collagen synthesis, and have effects of skin whitening, anti-wrinkle and anti-oxidation.


High-end whitening cosmetics. As replacement of VC, AA2G has now become the new favorite of whitening cosmetics due to its high stability.

AA2G Characteristics

  • AA2G is very stable in aqueous solution, because it has non-reducing activity, and it’s hard to undergo oxidation reaction.
  • AA2G has good light fastness and heat resistance, it’s not easy to decompose under the high temperature heating condition for a long time.

AA2G Benefit and Dosage

Skin whitening

AA2G can convert into VC by enzymatic hydrolysis after entering skin cells. VC is able to inhibit the activity of tyrosinase, and then significantly reduce the formation of melanin. Also, VC can accelerate the reduction of the formed melanin to the original state. Therefore, AA2G has a high-efficiency whitening function, and its whitening effect is more obvious and faster than other additives.


AA2G will continually hydrolyze to produce Vitamin C after entering cells, which can promote the synthesis of collagen, accelerate the metabolism of skin tissue, prevent wrinkles and increase skin elasticity. At the same time, VC is a water-soluble antioxidant that scavenges free radicals from body and delays skin aging. Therefore, AA2G has the function of anti-aging and anti-wrinkle function.

AA2G application

AA2G is mainly used in whitening and anti-freckle cosmetics, such as lotion, toner, essences, masks, face creams, and so on.

--Recommend additive amount: ≤2.0%



  • AA2G should be cultured with alkaline substance before being added to cosmetic formulation;
  • AA2G should be avoided to be placed in a strong acid (pH 2-4) or strong base (PH 9-12) environment for a long time;
  • Formulation containing AA2G needs to be heated, the temperature should be below 40 °C and then add AA2G solution.


AA2G (Ascorbic Acid 2-Glucoside) has been approved by Japanese government for use as a cosmetic additive.

Reference formula

Whitening cream

1. Heat group A and group B respectively to 80℃, stir until all ingreidents are melted and uniform;

2. Add group B to phase A slowly, and emulsify to homogenize for 10 minutes;

3. Stir slowly and cool to 50℃, add group C, continue to stir;

4. When the temperature is lowered at 36-38℃, it’s finished.
