Struggling with persistent sweat stains? Excessive sweating occurs even without triggers like heat or physical activity and can cause discomfort, embarrassment, and difficulty in social or professional settings. Prolonged moisture can also lead to skin problems, such as fungal infections or rashes. Excessive sweating commonly affects the palms, feet, underarms, and face. Botox injections temporarily block the nerves that trigger sweating and are often used for underarms, hands, and feet. The effect lasts 4-6 months.
