The pulp of the papaya fruit can help reduce wrinkles. Papayas contain an enzyme called papain that is known as a digestive enzyme that can also help repair wrinkles. The skin is made of tissues that stretch with age. Elastin and collagen are two fibers in the skin that contribute to skin firmness and help to restore skin elasticity. Papayas help rebuild the elastin thereby rebuilding healthy skin and preventing wrinkling.
