A synthetic progestin used in hormonal contraceptives and hormone therapy, with no general authorization for cosmetic use in the EU.
Etynodiol (17-alpha-ethynyl-5(10)-estren-17-ol-3-one or 19-norprogesterone derivative) is a synthetic progestogen used in oral contraceptives and hormone replacement therapy. It has pharmaceutical potency and is not listed in EU CosIng as a general cosmetic ingredient. While it may appear in some dermocosmetic or anti-aging products targeting hormonal skin changes, its use requires strict regulatory compliance and safety evaluation due to its systemic hormonal effects.
Known concerns
