SweatStop

SweatStop is a line of over-the-counter (OTC) topical antiperspirants developed by Alto Pharmaceuticals for the treatment of hyperhidrosis, particularly axillary hyperhidrosis. The product line contains varying strengths of aluminum chloride as the active ingredient, which works by forming temporary plugs in the sweat ducts to reduce perspiration. Available in various formats such as roll-ons, sprays, and lotions, SweatStop formulations often include skin-caring ingredients like Aloe Vera and provitamin B5 to minimize irritation. It is applied directly to the skin in affected areas to prevent excessive sweating and eliminate associated odors.
