SweatStop (Blaine Labs)

SweatStop is a topical antiperspirant product line developed by Blaine Labs for the treatment of hyperhidrosis and excessive sweating. Unlike traditional antiperspirants that rely on aluminum salts to block sweat ducts, SweatStop formulations use tannic acid (3%) as a plant-based astringent. Tannic acid works by precipitating skin proteins, which acts as a natural drying agent to reduce moisture at the source. The product line includes the SweatStop Astringent Spray and SweatStop Moisture-Reducing Body Spray, which are marketed as aluminum-free, paraben-free, and aerosol-free. These products are designed for application to the hands, feet, underarms, and other body parts affected by excessive perspiration.
