What role does Östradiol play in Haut?

Estradiol (E2), the primary estrogen, significantly influences skin health by stimulating collagen production, maintaining dermal thickness, hydration, and supporting wound healing. Declining estradiol levels, especially during menopause, are linked to skin aging, wrinkling, and loss of elasticity. Topical estradiol is used in some dermatological treatments, but systemic hormone therapy for skin benefits lacks robust long-term evidence. Consumer DNA tests that claim to predict skin aging via estradiol-related genes (e.g., CYP1A1, COMT) have weak clinical validity; effect sizes are small and not actionable. Evidence is primarily mechanistic or from observational studies. Do not base skincare decisions solely on such tests. Safety note: Unsupervised hormone use carries risks including thromboembolism and hormone-sensitive cancers. Always consult a physician before any hormone intervention.
