The numbers say it all

miraDry is the first and only non-invasive treatment that provides a lasting solution for excessive underarm sweat and odor.

Published studies have shown the treatment to be highly effective: more than 80% reduction in underarm sweat while delivering over 90% patient satisfaction. A recent clinical study reported an 82% sweat reduction at 12 months post-treatment. In the same study, patient satisfaction was 94% at 18 months. In many cases, miraDry procedure has a 100% patient satisfaction rating!


Long-term studies demonstrate that miraDry is effective for permanent reduction of both sweat and odor(1)

Clinical studies

From a scientific and clinical perspective, miraDry results are measured using Hyperhidrosis Disease Severity Scale (HDSS), gravimetric assessment (weighing sweat) or Dermatology Life Quality Index (DLQI).

  1. Hyperhidrosis Disease Severity Scale (HDSS) – This measurement of miraDry results has consistently demonstrated a significant reduction. In one recent study published in Practical Dermatology, over 90% of patients demonstrated a reduction in HDSS to level 1 or 2 at 12 months post-treatment.
  2. Gravimetric Assessment – In the same study quoted above the researchers observed an average decrease of 82% at 12 months post-treatment.
  3. Dermatology Life Quality Index (DLQI) – This is a standardized patient questionnaire that measures a conditions impact on one’s quality of life. Excessive sweating has been shown to impact patients’ lives on a level similar to acne or psoriasis. It is a 10-question test that takes about 2 minutes to complete and it is scored on a scale of 0-30. Improvements of 5 points are considered impressive. Multiple miraDry studies show this level of improvement in over 80% of patients.

Clinical practice

In addition to the standard scientific and clinical means of measuring miraDry results, the dermatologist may apply some other common sweat tests with you: the startch iodine test, sweat stain assessment on your shirt or blouse, or the Illness Intrusiveness Rating Scale.

  1. The startch iodine test – This is a popular qualitative test that uses iodine and starch to help visualize the degree of sweating. Essentially your armpit is swabbed with iodine and then dried off and dusted with corn starch. When you sweat the starch turns dark purple. More sweat, more purple the starch turns! It may be used to help identify overactive or treatment-resistant areas.

Starch iodine test in axillary region: ① The inky areas show where the patient is still sweating before the treatment

② The treated area without sweat post-treatment.


2.  Sweat Stain Assessment The “pit test” shows how big is the sweating problem in accordance with the sweaty pits stains in the shirt you are wearing.

3.Illness Intrusiveness Rating Scale – This is similar to the DLQI and is an alternative to measuring how a condition impacts a patient’s daily life.



From a patient perspective, measuring miraDry results usually comes down to two basic criteria: quality of life measurements and patient satisfaction after miraDry treatment.

  1. Quality of life – This is an answer to “How would you explain your miraDry results?” Did it work for you? Did it provide the results you were hoping for?
  2. Patient SatisfactionWas it worth it? This takes the Quality of Life question on step further and asks were the results worth what you had to pay? Were they worth the whole process? Were they worth the downtime? Given that miraDry results have a very acceptable side effect profile, have little to no downtime, and viewed as affordable, it is not a surprise that over 90% of patients say it was “worth it.”
