Postmenopausal Facial Skin After Estradiol and Genistein Topical Treatment
Summary
The aim of this trial was to compare the effects of estradiol or genistein treatment on the hialuronic acid concentration on the postmenopausal facial skin. In this study, 30 postmenopausal women were evaluated through a prospective, randomized, double-blind trial. The volunteers were postmenopausal women treated in the Gynecology Department of the Federal University of São Paulo (UNIFESP). The participants were divided into two groups: group E, treated with 17 β estradiol gel 0.01% (n = 15), and group G, treated with genistein gel 4 % (isoflavones, n=15). The length of treatment was 24 consecutive weeks. Preauricular skin biopsies were performed on each patient before and after the treatment for evaluating hyaluronic acid in the tissue. The materials were processed through immunohistochemical and biochemical methods.
