How are Östradiol and Haut related?

Estradiol, the primary estrogen, significantly influences skin health. It stimulates collagen production, maintains skin thickness, and enhances hydration via hyaluronic acid. Declining estradiol levels, e.g., during menopause, are linked to skin thinning, dryness, wrinkles, and impaired wound healing. Estradiol also plays a role in acne and pigmentation disorders like melasma. Evidence is mainly observational and mechanistic; robust RCTs are limited. Effects are moderate and modulated by lifestyle, UV exposure, and genetics. Hormone replacement therapy can partially reverse skin changes but carries risks.
