Main function

Function of Ursolic acid 

1. Pharmacological Action:

Medicinal plants containing ursolic acid have been used in folk medicine before it was known which constituents were responsible for their therapeutic effectiveness.

2. Anti-aging agent:

Ursolic acid treatment improves the health of skin and hair. Ursolic acid and its derivatives form oil-resistant barriers on the skin and hair as they do in the waxy coating of fruits. Ursolic acid has been used to treat photoaged skin because it prevents and improves the appearance of wrinkles and age spots by restoring the skins collagen bundle structures and its elasticity.

3. Hair growth stimulant:

Ursolic acid and its isomer, oleanolic acid, have been used in to nics to enhance hair growth and prevent scalp irritation. Both triterpenoid compounds encourage hair growth by stimulating the peripheral blood flow in the scalp and activating the hair mother cells. They also furnish alopecia-preventing and dandruff-preventing effects.

4. Antimicrobial activity:

β Ursolic acid (triterpenoid sapogenin from the ursan group) inhibited the growth of several strains of staphylococci. Numerous ursolic acid containing plants from the Lamiaceae family exhibited antibacterial/ fungal activity.

5. Skin care

Ursolic acid treatment improves the health of skin and hair. Ursolic acid and its derivatives form oil-resistant barriers on the skin and hair, just as they form the waxy coating of fruits. Ursolic acid has been used to treat photoaged skin, because it inhibits the appearance of wrinkles and age spots by restoring the skins collagen bundle structures and elasticity.

Function of Arbutin 

Arbutin is the active substance originated from natural plant which can whiten and lighten skin. It can infiltrate into the skin quickly without affecting the concentration of cell multiplication and effectively prevent activity of tyrosinase in the skin and the forming of melanin. By combined arbutin with tyrosinase, decomposition and drainage of melanin are accelerated, splash and fleck can be got ride of and no side effects are caused. It is one of the safest and most efficient whitening materials that are popular at present. It is also the most competitive whitening activity in the 21st century.
