What role does Östradiol play in skin aging?

Estradiol, the primary form of estrogen, plays a key role in skin aging. It promotes collagen synthesis, maintains skin thickness and hydration, and supports elasticity. As estradiol declines during menopause, collagen production drops, leading to thinner, drier, and more wrinkled skin. Estradiol also influences sebum production and wound healing. The evidence is human-strong, based on clinical studies and dermatological consensus. However, the context mentions DNA tests (e.g., MyBody-X DNA Longevity) that analyze single SNPs with small effect sizes – they cannot clinically predict skin aging from estradiol. Lifestyle factors (diet, UV protection, smoking) dominate skin aging. A hormone test can measure current estradiol levels, but interpretation for skin aging is individual and should be medically guided.
