Excessive sweating, called hyperhidrosis, can be localized in some regions, such as: armpits, groin, hands, feet and scalp, and be quite embarrassing, damaging the social and professional life of people. The botulinum toxin is extremely effective in the armpits, groin, hands and feet, drastically reducing sweating, often by 100%. However, in the palms of the hands, there may be slight decrease in muscle strength.
The product is given through injections into previously anesthetized skin, which makes the application less painful. The maximum effect occurs in about 2 weeks and can last up to 8 months or longer. On the other hand, another technique to treat excessive sweating, surgery (Video-Assisted Thoracic Sympatectomy), presents as a side effect in 20 to 80% of cases compensatory hyperhidrosis, which is the appearance of excess sweating elsewhere, usually On the trunk. When botulinum toxin is used for treatment, there are practically no side effects and the results are excellent, greatly improving the patient’s quality of life.
