Is a Single MiraDry Treatment Enough to Provide Permanent Sweat Reduction?

I underwent the MiraDry procedure 2 months ago, & now I'm seeing some of my ability to sweat return to the treated area. The company (Miramar Labs) claims that at least 2 treatments are necessary to achieve "lasting" results. I want to know the following: if I just stop now and do not get treated a second time, do I retain permanent reduction in sweat, or does my sewat return to normal if not treated a second time ? Is it absolutely necessary to receive a second treatment for permanent results ?

New Miradry Protocol

Great question! With the new treatment pathway for Miradry, the advice is one treatment at level 5. With these increased settings, one session is needed for most patients.

Single miraDry treatment enough for most patients

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Everyone gets a permanent sweating reduction with their first miraDry treatment. However, only about 80-85% of the sweat glands are killed. So there can still be slight noticeable sweating after the first treatment, but it is usually not enough to need any antiperspirant. In our experience, only about 1 in 10 patients request a second treatment to be completely dry. 

Newer protocol results in vastly decreased sweating with one treatment

The protocol has been optimized and patients now typically need only one treatment.  The rare patient needs a second treatment.  

Please note that miraDry reduces sweat by greater than 80% on average, but it does not completely eliminate it.  For heavy sweaters, an 80% reduction means that you will still sweat, but an amount that is socially acceptable.

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.

How Many miraDry treatments are Recommended

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Hello and thank you for your question! When using the newest protocols for miraDry, the recommendation is one treatment at level 5. With these advanced settings, one treatment is expected for most patients, potentially a second dependent on the patient, amount of hyperhidrosis, etc. In addition, miraDry has received an FDA indication for approximately 70% hair removal of all colors. So in addition to resolving sweat and odor, you can also see a reduction in hair. Please call our office for a complementary consultation with our Nurse Practitioner, Jennifer Tinelli. Thank you!

2 treatments recommended

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
miraDry recommends 2 treatments, because of several reasons-
1. Patients vary in sweat gland numbers
2. Patients vary with the thickness of the axillae or underarms
3. The treatment levels will vary with patient to patient. 

Undergoing two treatments will give you the probability of 80-90% sweat reduction for life.

MiraDry - 1 or 2 treatments ?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The company recommends 2 treatments. After doing this procedure for nearly 3 years as of this writing (Septembe 2013), I have changed my practice to routinely perform miraDry at level 5 and to perform 1 treatment and leave it to the patient to return for a second treatment if they don't achieve the clinical dryness they are seeking. As such, we have changed our practice to charge 1,500 for the first treatment and this seems to be more affordable for patients They don't have to pay the full amount of 3,000 dollars if they do not need a second pass at 90 days. Nobody has shown in a scientific study whether delaying the second treatment to 90 days, 180 dyas or 360 days after the 1st treatment reduces overall treatment efficacy - i.e. less than the 86% reported by the company with 2 treatments spaced 90 days apart.

2 Treatments of miraDry for better results

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

For optimal results, we recommend two miraDry treatments spaced 3 months apart.  Although you will likely achieve a 40-50% reduction in sweating after one treatment, two treatments are necessary to obtain a sweat reduction as high as 86% in most patients.  The miraDry procedure utilizes microwave technology to selectively target and eliminate sweat glands in the armpits by focusing electromagnetic waves at a specific level in the body where swat glands are located.  Studies demonstrate that results last up to 2 years and are likely permanent as sweat glands do not regenerate.  Patients may initially note an increased reduction in sweating after the first treatment that gradually wears off because while approximately 40-50% of the sweat glands are gone, some may be temporarily stunted.  That is why it is advisable to have the second treatment for optimal results and full eradication of sweat glands.

MiraDry - One treatment is usually not enough.

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

MiraDry typically provides great sweat relief after two treatments and thus many places sell the two treatments as one package.  You will probably experience a sweat reduction after one treatment and if your symptoms were only mild/moderate to begin with, then you may find one treatment adequate, but some of the sweat glands are still functional after one treatment.

MiraDry Consists of a Series of Two Non-Invasive Treatments

Dear Marcel1982,

MiraDry typically eliminates about 50% of underarm sweating after one treatment and 85% after two treatments.

Two treatments are absolutely recommended for proper results.

Warmest wishes,
