A Minor’s starch iodine test may be performed prior to your treatment to determine the potential treatment area. This involves applying iodine to the area you experience excessive sweating allowing it to sweat and once it dries a small amount of starch is placed on the affected area highlighting the affected areas in dark blue colour. Experienced medical professionals who treat hyperhidrosis will inject a small amount of botulinum toxin into each affected area to control sweating.
The entire process takes about 30 minutes per area treated, though you might need more than one session if your sweating is severe or widespread over several body parts such as the forehead, back and feet.
The injected area can be numbed beforehand so you don't feel too much pain, but you may see some redness and swelling in your armpits following injectable treatments.
This will settle after a few hours and you can go back to your normal routine straight away. Results usually take two weeks to take effect and you will not need to apply deodorant when the botulinum toxin starts working.
Botox injections are not a permanent treatment for your excessive sweating problem, but it usually lasts between three to six months. If you sweat excessively, you may need to book follow-up treatment for additional injections during this time period, so be sure you are committed to using Botox to treat underarm sweating before going ahead with treatment.
