Monthly determinations of estradiol found to be effective in endogenous aging. Although (E2), follicle-stimulating hormone (FSH), and prolactin (PRL) were hormones often were considered as important factors in done and the monthly clinical monitoring was supplemented by endogenous skin aging, the scient i f i c background of a measurements of skin hydration by corneometry and profilometry. hormonal role in the aging processes of the skin still In 10 patients, skin biopsies were taken for immunohistochemical determination of collagen types I and III.
