Ethyl alcohol (ethanol) is a volatile, low-molecular-weight solvent used in cosmetics for rapid drying, product clarity, antimicrobial support, and as a penetration enhancer. In skincare it is most common in toners, sprays, gel products, and some acne or fragrance formulations. It can improve feel and drying time but may also increase skin dryness and sting, especially in higher concentrations or on impaired barriers.
