Ageing is the process of growing old. It is a continuous time dependent and multi factorial phenomenon of reduction in size and number of cells and also reduction in the rate of many organic functions both at cellular and molecular levels. Skin is the largest and the most superficial organ of the body which is exposed to infection, disease and injury. It also shows the signs of ageing the earliest. Skin functions that have shown to decline are cell replacement, injury response, barrier function, sensory perception, immune and vascular responsiveness, thermoregulation, sweat production, sebum production and vitamin D production
