Modulação nutricional no envelhecimento cutâneo: uma revisão

Abstract

The objective of this study was to identify the nutrients that can be used in the modulation of skin aging.This study was carried out through a bibliographic review of original or review articles, written in Portuguese and English, published between the years 2008 and 2017, searched in the databases Scielo, PubMed, Google Academic and LILACS.The article addresses the structural aspects of the dermis and the effects of aging on the skin, discussing the various ways of modulating the expression of aging and its clinical signs through the oral use of protective foods and / or nutrients.In order for dietary constituents to effectively reach nutrients in the lower region of the skin and provide systemic photoprotection, they must have some of the following functions: avoid absorption of ultraviolet light through the skin, protect target molecules by eliminating free radicals, induce Systems and suppress the inflammation caused by responses to the damage caused.Using supplementation or elimination diets, the area of nutrition has aroused interest to help prevent the onset of signs of aging, reduce the severity of these signs and prevent recurrence.A good strategy is to match the amount of antioxidants in the diet, through regular consumption of food sources such as polyphenols, omega-3 fatty acids, coenzyme Q10, vitamins and minerals from fruits and vegetables. As presented in this review, it is suggested supplementation to adapt the needs aiming to achieve improvement in clinical and aesthetic parameters.
