Clinical Results

The miraDry Treatment has been proven, in multiple rigorously controlled studies and in over 70,000 commercial treatments, to deliver excellent efficacy, a strong safety profile, and high patient satisfaction.


Patient A: partial treatment. Post-treatment starch iodine tests demonstrate dramatic and permanent sweat reduction.

Zone of Treatment

3 Months

2 Years

3 Years

Patient is nearly sweat free in the area treated but continues to sweat in the area untreated.

Clinically Proven

Published studies demonstrate destruction and elimination of sweat and odor glands and permanent reduction of sweat.

Human histology illustrates sweat gland destruction.

Normal sweat glands


Sweat gland cells devoid of nuclei – complete celluar necroisis

10 days POST-TREATMENT sample

No sweat glands

180 days POST-TREATMENT sample

“The ontogenesis of sweat glands is only at the embryonic period, so no new sweat glands are regenerated after birth.”1 Therefore, results are permanent.

Long-term studies demonstrate that miraDry® is effective for permanent reduction of sweat2.


Long-term findings of approximately 70% reduction in underarm hair in patients in both light and dark axillary hair was seen, and is stable through 12 months of follow-up3.

Average Hair Reduction from Quantitative Assessment for each follow-up visit. Results for light and dark hair are broken out separately for the initial 3m and final 12m visits.

Results of side-by-side qualitative analysis per axilla. Percentage of axilla where the blinded reviewer correctly chose the baseline photo (green bars); % where assessor rated the reduction as being at least 50% (blue bars).
