Skin aging is a complex, multifactorial process that results in dramatic changes in both skin structure and function, being manifested as wrinkles, fragility, atrophy, increased laxity, and others. 1,2 As skin ages, its physiological role gets compromised, meaning an augmented vulnerability to mechanical trauma; longer healing time; higher susceptibility to infection, bruising, tearing, photocarcinogenesis; and greater sensitivity to external agents. 3 The skin undergoes intrinsic aging, mainly driven by genetic and hormonal influences, and extrinsic aging, given to its location, mediated by UV radiation, smoking, diet, chemicals, trauma, and other
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
