With the age, the collagen present in the skin gets reduced, so skin loses its elasticity & moisture resulting in wrinkles or creases, which can be the signs of ageing. As development of wrinkles is a biological process, but free radicals and UV rays can speed up the process of formation of wrinkles at early age. Usually wrinkles are found in the body parts like face, upper arms, neck, hands, legs, etc.
