Skin Ageing

Abstract Skin ageing is an inevitable phenomenon with several characteristic manifestations. The genetic, molecular, and cellular factors that contribute to aged skin are becoming increasingly understood. As our knowledge of how skin ages advances, the potential therapeutic opportunities for skin rejuvenation are similarly increased and improved. In this chapter, the process of skin ageing based on both intrinsic factors and extrinsic influences across the spectrum of skin types is discussed. The biological mechanisms that contribute to these phenomena are further discussed, as well as the progress and opportunities for therapeutic interventions.
