Thank you for your question, and congratulations on your choice to say goodbye to underarm sweat and odor! The results of miraDry are immediate due to the removal of underarm sweat and odor glands during the procedure. Once these glands are eliminated they do not grow back, resulting in immediate and lasting results. Recent clinical studies have confirmed an average of 82% of sweat and odor reduction in patients, with 90% of patients only needing one treatment (you will also see an added benefit of underarm hair reduction). Results of the treatment may vary from patient to patient, so give your body two to three months to see final results before questioning if you will be needing a second treatment. If you have any further questions or concerns regarding your treatment, I would reach out to your miraDry specialist.
