Abstract:
Background: Aging is associated with declining levels of estrogen. Hormonal replacement therapy is known to benefit this condition, but carries many side effects. Topical estrogen, especially in estriol form, is safer. Objective: To determine the efficacy of 0.1% estriol cream on aging skin in postmenopausal women. Materials and Methods: In 6 months trial, 34 postmenopausal women were divided randomly into 2 groups, 17 persons in each group, received 0.1% estriol cream or placebo cream twice per day. Efficacy was evaluated by visiometer for wrinkles, corneometer for humidity, cutometer for elasticity and patient satisfaction. Safety was assessed by clinical and serum estradiol level. Results: All participants completed the decided treatment Age between 45 to 63 years. Mean age was equally in both groups. Treatment with 0.1% estriol cream decreased wrinkle on aging faces at 6 months (p=0.012) VS placebo. Humidity and elasticity were increased, compared with placebo (p value= 0.002, p value< 0.001). In estriol group, one participant had breast tension, one complained aggravation of preexisting melasma. After treatment, both treated group and placebo group had normal estradiol level in serum. Conclusion: In postmenopausal women, 0.1% estriol cream has been shown to decrease wrinkles and increased humidity, elasticity when compared with placebo.
