How Long Will MiraDry Last?

Doctor Answers 17

MiraDry results should be permanent

Preliminary study results show effects lasting for two years.  However, results should be permanent, as sweat glands do not regenerate.

MiraDry is essentially permanent.  The device irreversibly destroys sweat glands of the underarm.  These glands have not be demonstrated to regenerate or grow back.  Clinical trials report 85 percent efficacy after 2 treatments spaced 3 months apart....

Best of luck!

Long lasting results after miraDry treatments

MiraDry is the only FDA-approved procedure that offers long-lasting results for excessive sweating.  Studies demonstrate that results last up to 2 years and are likely permanent as sweat glands do not regenerate.  Botox injections also work to help decrease sweating, but results are most temporary as injections need to be repeated every 4-6 months with Botox effects wearing off near the end of that time frame.

MiraDry is durable

miraDry is a durable procedure but remember that outcome studies to date last 2 years, not longer. There is no reason why you should start sweating again after 2 years. The technology behind miraDry for excessive underarm sweating is FDA approved.

Miradry is Permanent Reduction of Sweating

MiraDry permanently kills the sweat and odor glands in the underarm area.  There is an 80% reduction in sweating with one treatment in the majority of patients - very few patients need two treatments.

Is miraDry permanent?

Sweat glands do not regenerate so miraDry is expected to be permanent.  The studies show 2 year results thus far.

Although miraDry is getting a lot of attention recently, it has actually been around for a while. It has been extensively studied and there is no cancer association. The FDA has cleared it for safe use as well. The microwave energy only penetrates 4-5mm in depth and heats up and destroys the sweat and odor glands. The energy does not reach lymph nodes or deeper structures and it in non-ionizing radiation (the safe kind, like radiowaves). I have had the procedure done myself and it has truly been a gift. One and done for 80% of people! In the long term, much more cost-effective than Botox which has to be repeated every 3-6 months. Let us know if we can help in any way.
Botox can be a good alternative while miradry is being approved for use in those areas. Botox prevents the nerves from telling the sweat glands to produce sweat and odor. Hope that helps!
And we are the busiest miraDry practice in California with great results. Let us know if you can help in any way.

Miradry working very well.

The Miradry has not been available for a long enough period to give long term data on this topic. However, all the patients I have treated have not had a recurrence of their sweating. Our practice was one of the first to obtain the Miradry, appox 3 years ago. It is a solid treatment for underarm sweating, and has changed the lives of my patients who had suffered with sweating for so many years.

Longevity of MiraDry benefit

We now have enough clinical data to declare the benefit of MiraDry for underarm excessive sweating, or hyperhidrosis to be semi-permanent. On average, 50% reduction of sweating can be experienced with first treatment and 85% reduction with second treatment 3 months later. Histologic studies have demonstrated that once sweat glands have been wiped out, they are not known to regenerate.

MiraDry Results

The preliminary studies showed that MiraDry results lasted 2 years however, since sweat glands can not regenerate themselves, the results should be permanent.
