Estrogens are known to have protective and favorable influences on skin health; conversely, androgens oppose the actions of estrogens. Estrogen's chemical messages are transmitted via the classical nuclear hormone estrogen receptors (ER) alpha and beta and the rapid-acting G-coupled membrane estrogen receptor. Androgens [both testosterone and 5α-dihydrotestosterone (5α-DHT)] bind the same androgen receptor. Estrogen levels peak in the mid- to late 20s in women and then decline by 50% by 50 years of age and dramatically decrease further after menopause. The loss of estrogens with aging contributes to diminished dermal health, whereas estrogen hormone therapy [eg, oral conjugated equine estrogens (CEE)] restores skin health. Several reports suggest positive correlations between the levels of circulating estrogens and: (1) perceived age, (2) attractiveness, (3) enhanced skin health, and (4) facial coloration in women. Based upon a psychological dermato-endocrine perspective, the positive correspondence of high estrogens levels with perceived age and facial attractiveness in women especially with aging demonstrates the importance of hormonal influences on observed dermal health and youthful appearance.
