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^6. Ursolic acid has been used to treat photoaged skin because it prevents and improves the appearance of wrinkles and age spots by restoring the skin's collagen bundle structures and its elasticity³¹. Concentrations of ursolic acid ranging from 0.01 to 50 mg have been reported for inclusion in skin treatment preparations ^32-33.
