The procedure consists in administering a small amount of botulinum toxin to each square subcutaneously. 15 minutes before the procedure, the anaesthetic cream is applied and the self-injection is carried out using an additional cooling fan. As a rule, the procedure performed on the hands and feet requires anaesthesia. The procedure itself takes a few dozen minutes, and you can return to your daily activities. The effect is visible after a few – a dozen or so days, and lasts for several months. It lasts up to a year (armpits). Then it needs to be repeated.
Local non-surgical treatment – intradermal injection of botulinum toxin
Before starting the procedure, the field of excessive sweating should be clearly determined. Most often, places requiring botulinum toxin injection overlap visibly with drops of sweat. However, sometimes, it is extremely difficult to identify this field accurately. For this purpose, the so-called iodine starch test (Minor test). It involves spreading a given place with iodine and then sprinkling with potato starch. The areas sought after several or dozen of seconds become more and more blackened. The spots of excessive sweating found are divided into 1.5 x 1.5 cm squares with the support of a solution like a gentian violet.
It involves the surgical removal of all sweat glands under the arms, sometimes also with the excision of the skin of the area. Fat subcutaneous tissue in the underarm area is always removed. The successful result of the procedure reaches 90%, but it is associated with the formation of scars that may lead to the limitation of the range of arms movement. For some people, discomfort brings loss of hairy skin in this area.
Combined method: laser removal of sweat glands + liposuction of the area armpits:
A thin cannula connected to the laser is inserted through the small incision of the skin. After irradiation of the gland with a quartz optical fibre powered by laser light, the doctor performs small liposuction of the area.
