RESUMO

With a view to identifying knowledge about the ageing process of the tegumental system, characterized as senescence, in spite of the occurrence of different related skin conditions, this study used the integrative method (Ganong, 1987) for reviewing literature about the tegumental system. The articles were analyzed quantitatively as well as qualitatively, on the basis of a data collection script in accordance with the following six identification criteria: author; profession and affiliation; country of origin and periodicals; characteristics of the studied sample; types of study models; research aims; knowledge about the subject under analysis. The sample consisted of fifty-seven publications, most of which were written in English. The research aims involved: levels of elastin, skin functions in elderly persons, advances in molecular genetics, accumulation of mitochondrial DNA extinction and skin ageing, levels of hyaluronic acid, cutaneous ageing and geriatric dermatoses, skin collagen and bone mass during the ageing process, and spots in people who were submitted to radiation. As skin ageing is not only associated with the chronological criterion, but also with external aspects related to the persons’ way of life, such as, for example, kinds of diet, exposure to the sun and emotional health, among others, it is important to get to know the intrinsic implications of the ageing process, in order to seek alternatives that minimize the impacts suffered through ageing. This study discloses intrinsic and extrinsic ageing, as well as the main epidermal and dermal modifications during ageing, pointing out the need to continue research aimed at changes in elderly persons’ tegumental system and, mainly, the need for national studies and experiments in this field.
