• Ascorbic acid, commonly known as vitamin C, is a common component of human skin, concentrated in the dermis and epidermis.
• Ascorbic acid has the function of inhibiting tyrosinase activity, so it can be used for skin's antioxidation.
• However, when exposed to air or light, ascorbic acid due to its own structural reasons, the nature of instability, easy to be oxidized.
• Ascorbic acid derivatives are well known for their unstable properties, in which the fatty alkyl and fatty acyl derivatives of ascorbic acid belong to the ester-affinity category.

Ascorbic acid isostearate is an oil-soluble vitamin C derivative, which has excellent solubility and can be dissolved in various oil-based components, and has the same function as ascorbic acid stearate, but the formula is easier to use.

After skin absorption, enzyme can be in the body under the physiological environment can be converted to vitamin C, thus improving the oxidation of vitamin C discoloration defects.

18 mg/mL(≈1.8%)DropBrigt® VCI inhibited tyrosinase activity by 96.3% .
According to the dose-response curve, the IC50 value was 8.2 mg/mL.
According to the experimental conclusion, DropBrigt® VCI can effectively inhibit the activity of tyrosinase, thus reducing the production of melanin, play a whitening and brightening effect of skin.
