Abstract
The present work was designed to explore certain aspects concerning human skin in the domain of sun exposure. Skin biopsies were taken from fifteen subjects divided into two groups; chronically sun-exposed group consisted of 10 subjects and control group consists of 5 subjects with no history of chronic sun exposure. Histological signs of sun-damaged skin were prominent as a pronounced thickening of stratum corneum indicating a hyperproliferative state accompanied by a corresponding decrease in collagen content associated with large bundles of coarse abnormal elastic fibers. Depletion of Langerhans immune cells in addition to decreased nuclear DNA was also observed.
