Ursolic Acid
Ursolic acid has anti-irritation properties. Ursolic acid is present in many plants, especially in extracts of pomegranate, rosemary, Greek sage (salvia triloba), oleander, periwinkle, spike lavender and more. Ursolic acid increases ceramide and collagen and helps preserve the structure of collagen fibers. These properties, together with its inhibition of elastase activity, make it a good anti-aging and anti-wrinkle ingredient.
