Concerns about skincare ingredients disrupting hormones have become increasingly common, but they are largely unsupported by scientific evidence. For a substance to meaningfully interfere with hormonal signaling, it must penetrate the skin, enter systemic circulation in sufficient amounts, remain biologically active, and bind hormone receptors at physiologically relevant levels. Cosmetic ingredients simply do not meet these criteria. Even under exaggerated exposure models that assume daily, lifelong use and enhanced absorption, safety assessments consistently show exposure levels far below those capable of affecting endocrine function. Evidence-based skincare is not a threat to hormonal health, and fear driven avoidance often does more harm than good.
