How are Östradiol and skin aging related?

Estradiol, the primary form of estrogen, significantly influences skin aging. It promotes collagen synthesis, skin thickness, hydration, and wound healing. The sharp decline in estradiol during menopause accelerates skin aging: reduced elasticity, increased wrinkling, dryness, and thinning. Evidence from observational and some interventional studies indicates that hormone replacement therapy (HRT) can partially counteract these changes, but carries risks (e.g., thrombosis, breast cancer). The evidence level is moderate: the association is well-documented, but individual variability (genetics, lifestyle) and study limitations exist. Consumer tests measuring estradiol cannot diagnose or predict skin aging because hormone levels fluctuate and skin aging is multifactorial. A dermatologist or endocrinologist should interpret any hormonal findings in context.
