Myths vs facts: Östradiol and Haut

Estradiol (E2) acts on skin via estrogen receptors, stimulating collagen production, hyaluronic acid synthesis, and vascularization. Fact: Declining E2 after menopause correlates with thinner skin, increased wrinkling, and dryness. Myth: Topical estradiol is a safe fountain of youth. Evidence shows that unmonitored use can lead to systemic absorption and risks (e.g., endometrial stimulation). Most data come from mechanistic and observational studies; robust clinical trials on cosmetic anti-aging are lacking. Some products claim 'plant-based estrogens' work like estradiol – but efficacy and safety are poorly supported. Conclusion: Estradiol has real dermatological effects, but marketing often exaggerates. For medical indications (e.g., vulvovaginal atrophy), low-dose topical estradiol is evidence-based. For general skin rejuvenation, the risk-benefit ratio is unclear. Always consult a physician before using hormone-containing skincare.
