Is the starch-iodine test effective at determining the treatment zone or could it cause problem spots to be missed?

We use the starch-iodine test as a guide to help us capture the most active areas to treat. This test will help us adjust the treatment template placement on the axilla. The treatment template will cover the most active areas as well encompasses the entire hair follicle area. We always try to use the largest template when it’s feasible in order to achieve maximal improvement. Over the past several hundred patients that we have treated, our average improvement after single treatment is about 70% at 3 months and 60% at one year.

Its very unlikely the iodine-starch test would miss a spot, but I do like to treat the largest area which is "lit up" during the test. Most patients, have about 75 to 82 percent reduction in the sweat glands and some do need a second treatment to be even drier.
Best wishes, Dr. ALDO :)

Thank you for your question.It is better to treat the whole hair bearing area. Allow everything to settle and assess your sweating, if you have any concerns contact your practitioner.
