Senescence of people represents a global expression of obsolescence of their organs, tissues, cells and constitutive molecules. Skin, similarly to any other organ, is ageing in particular ways. Over the past century, the time effects on skin have been expressed differently. Skin of any individual presently engaged in the Third Age looks different from that of his/her line ancestral. What is the expected future? The Third Age population is expanding and skin problems call for a variety of management procedures. Prevention of the diverse types of skin ageing has made tremendous progresses particularly in the field of preventive and corrective dermocosmetology. The future should further speed up such trends.
