Effective Botox Therapy for Excessive Sweating by a Dermatologist
Hyperhidrosis, also known as excessive sweating, can significantly affect daily comfort, social confidence, and quality of life. Botox treatment is a proven and highly effective method to reduce excessive sweating by temporarily blocking the nerve signals that stimulate sweat glands. At our dermatology clinic in Izmir, Dr. Sedef Demirer provides personalized Hyperhidrosis Botox treatments with a strong focus on safety, comfort, and long-lasting results for both local and international patients.
Sweating is a natural physiological process that helps regulate body temperature and eliminate toxins. However, in some individuals, sweat production becomes excessive—most commonly in the underarms—leading to wet clothing, odor concerns, and social discomfort, particularly during warmer months.
Although factors such as stress, spicy foods, excess weight, and alcohol can increase sweating, many patients experience hyperhidrosis due to overactive sympathetic nerve stimulation even without clear triggers. In such cases, topical creams and deodorants are usually insufficient.
How Is Botox Treatment for Excessive Sweating Performed?
Botox is injected superficially under the skin at approximately 1 cm intervals in the affected area. This temporarily reduces sweat gland activity while allowing normal sweating to continue in untreated areas. The treatment effectively controls excessive sweating without disrupting the body’s natural balance.
Before the procedure, a topical anesthetic cream is applied to maximize comfort. The treatment typically takes 20–30 minutes, and its effects last an average of 6 months. When performed in spring, it often provides relief throughout the summer. Botox can be safely applied to the underarms, palms, and soles of the feet.
