Neurotoxin injections applied under the arm skin help people with excessive armpit sweating. Excessive sweating can affect patients' psychology and interrupt their social and work life. The toxin injected into the underarm area blocks the nerve signals sent to sweat glands, resulting in inhibition of sweat production. Patients will feel relieved after the treatment and regain their confidence.

A special test called the starch and iodine test may be required. This test is the gold standard to identify the exact region of sweating. However, this technique is mostly preferred for the second round if patients continue sweating after the first treatment. There is usually no requirement for a second round.
