Mechanisms of Skin Repair by Topical Estrogen
Completed · Not applicable
Conditions studied: Skin Wrinkling
In brief
The purpose of this study is to investigate the way by which estrogen improves the appearance of sun damaged human skin. Accumulating evidence suggests that estrogen, taken by post menopausal women, may cause skin to look younger as a consequence of reduced wrinkles. Collagen is the most abundant protein in human skin and gives skin its strength and shape. Recent data indicate that short-term topical estrogen (17-beta estradiol) treatment increases collagen production in sun damaged skin. This study will compare the molecular and microscopic effects from topical 17-beta estradiol (E2) when applied to the skin for a short-term duration. It is anticipated that the new knowledge from this study will enable development of new ways to improve the function of aged skin.
