Ursolic Acid, a carboxylic acid present in a wide variety of plants in the form of a free acid or an aglycone of triterpene saponines. It is also known as urson, prunol, micromerol and malol. It is a pentacyclic triterpenoid compound which naturally occurs in a large number of vegetarian food, medicinal herbs and plants.

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 skin's collagen bundle structures and elasticity. Ursolic acid inhibits the action of elastase enzyme in the skin, thereby preventing the enzyme from attacking structural proteines. Ursolic acid also inhibits the inflam-matory enzymes cyclooxygenase and lipoxygenase.
