miraDry is a nonsurgical, FDA-cleared treatment that uses electromagnetic energy to painlessly reduce the number of underarm sweat and odor glands, eliminating excessive sweating and odor (aka axillary hyperhidrosis).
Sweating is a natural and essential body function, however those with axillary hyperhidrosis tend to be self conscious of their condition (which can often cause stained clothing and even infections).
Your underarms contain only 2% of your body’s sweat glands, so you’ll still perspire elsewhere on your body after a MiraDry treatment, which doesn’t affect your body’s ability to cool itself. But miraDry can be a lasting solution for reducing underarm sweat.
The miraDry treatment is the only FDA-cleared treatment that can dramatically reduce underarm sweat by addressing the root cause of excessive sweat and its accompanying odor – not the symptoms.
The treatment works by selectively heating and destroying underarm sweat glands, causing an immediate reduction in sweating. As a bonus, miraDry also decreases hair growth in the treated area.
In the best-case scenario, one treatment reduces sweat by around 80% and odor by nearly 90%.
Short answer: Yes. The company that makes miraDry touts the results as immediate, and that patients see an average sweat reduction of 82% at 12 months post-treatment. Some reviewers on RealSelf agree that results are instantaneous, while others say they will take a few days. Wait a few days to see the effects of your first session before you decide whether to undergo another treatment.
One RealSelf member said in her review that she noticed a “permanent reduction in sweat, odor, and hair in my underarms after one treatment.” She added that miraDry was painless and “worked better than I thought.” The upshot: You’ll still sweat in other parts of your body, but your underarms won’t need platinum protection.
You’re a good candidate for miraDry if excessive underarm sweating impacts your daily life—the activities you do (or avoid), the clothes you wear. A 2016 study estimates that hyperhidrosis affects at least 4.8% of the U.S. population, with many of those afflicted never seeing a doctor for a formal diagnosis. You don’t need a hyperhidrosis diagnosis to get miraDry treatment.
It can be particularly helpful for people who experience stress and anxiety from their excessive sweating, including avoiding social activities and missing work opportunities because they’re worried about sweating in front of other people. A John Hopkins University clinical trial is currently exploring the psychological and social benefits of sweat reduction with miraDry.
The treatment can also be a good option if you’re sensitive to antiperspirant or deodorant and want to control wetness and odor in a different way.
Some patients only need one treatment, while others need two procedures, spaced three months apart. For people with severe hyperhidrosis, a third miraDry treatment can be necessary for optimal sweat and odor reduction.
If you’re still sweating after miraDry, another treatment session may help.
miraDry is generally considered to be very safe. After a treatment, it’s common for your underarms to be swollen, sore, or have changes in sensation like tingling or numbness.
Because there are other potential miraDry complications associated with the numbing process, it’s important to go to a physician-supervised office where the amount of numbing medication you can tolerate is safely measured and the staff has been trained in safe injection techniques.
