Processes in the human skin responsible for its aging

Abstract

With reaching biological maturity, the skin, like other organs, undergoes aging processes. They are mainly related to the regenerative processes of cells being slowed down, as well as their reduced biological activity. The above-mentioned molecular mechanisms at the cellular level have a significant impact on the phenotypic signs of skin aging. They cause typical morphological changes within each layer of the skin's integument. The characteristic appearance of aging skin is a clinical manifestation of changes within it. The aim of the article is to present the molecular mechanisms that occur during the skin aging process. There is no doubt that the aging phenomenon should be considered as the interaction of many factors of various etymology.
