Description:

Resveratrol, a non-flavonoid polyphenol organic compound, is an antitoxin produced when many plants are stimulated. It can be synthesized in grape leaves and grape skins as an active ingredient in wine and grape juice. 

What is the difference between grape and polygonum cuspidatum extract?

The main reason is the difference in composition. In addition to trans-resveratrol, grape extract also contains grape antitoxin, oligomeric beneficial bacteria such as paclitaxel; while Polygonum cuspidatum extract contains only trans-resveratrol. Grape skins are rich in polyphenolic compounds such as resveratrol, cellulose and anthocyanins.

Physical property:

[Appearance]:White crystal powder

[Physical Properties] :It is odorless, hardly soluble in water, and easily soluble in organic solvents such as ethanol 

[Application]: Because resveratrol has a variety of biological and pharmacological activities, it is widely used in food, medicine, health care products, cosmetics and other fields.

Function:

Skin Whitening

Resveratrol can be used as a skin whitening agent, inhibiting the activity of tyrosinase. It can reduce the pigmentation caused by ultraviolet light . It also fights photoaging by inhibiting the synthesis of melanin, thereby making the skin fairer and reducing chloasma .
