Is MiraDry Really a Safe Treatment for Hyperhidrosis?

Will the microwave energy in the MiraDry system destroy the fat as well as the eccrine glands, leaving one with "crepey" loose skin in the axilla following treatment? Any other potential downsides? For instance, can the glands regenerate following photothermolysis?

MiraDry is perfectly safe.  The technology essentially destroys sweat glands under the arm while protecting the skin and surrounding tissues.  Results after 2 treatments spaced 3 months apart have demonstrated an 85 percent reduction in underarm sweat production.

Best of luck!

Safe, and effective- cleared by FDA, CE and now Australia's TGA

Yes, miraDry is a supersafe treatment for excessive underarm sweating, also known as axillary hyperhidrosis. This treatment uses energy focused to the eccine or sweat glands and heats them up to give controlled destruction. A cooling device protects the upper layers of skin. To date, this treatment has been cleared as a safe and effective treatment for underarm sweating. 

Australia finally received its TGA approval last week- and treatments have begun in Australia. Results so far, have been outstanding, and well tolerated. 

Hope this helps,

MiraDry for hyperhidrosis

miraDry is a clinically proven and safe FDA-approved solution for significantly reducing underarm sweat. It’s an outpatient procedure performed in your physician’s office. It is not surgery so doesn’t involve surgical incisions. miraDry delivers controlled electromagnetic energy to the arm pit, eliminating the underarm sweat (eccrine) glands. It does not penetrate enough to cause significant fat reduction and if anything might tighten, not loosen skin.Two procedures are typically recommended. Each occurs approximately three months apart for best results.

Other options include: antiperspirants, Botox or Dysport with off label usage toxins temporarily prevents the sweat glands from working for varying lengths of time. This requires repeat treatments to maintain results. Other options involve superficial liposuction or excision of sweat gland skin poses additional risks and leave scars.

MiraDry is a safe and very long lasting way to deal with sweaty armpits!

As I am sure you have noticed, miraDry has a 98% approval rating from reviewers, patients just like you who have had the procedure.  From a scientific standpoint there have not been reports of fat loss or crepey skin (in fact if anything the skin could improve from treatment).  The energy is designed specifically to focus at the border between the skin and the subcutaneous tissue, a very few millimeters under the surface, where the sweat glands reside, not in the deeper fat layers.  As for sweat glands, once they are destroyed they do not regenerate. We know from tissue studies that the sweat glands are destroyed so you can expect lasting reduction in sweat.  The newest info follows treated patients for 2 years with no recurrance of their previous sweat levels.

Miradry and Sweat Glands

Once the microwave technology destroys the sweat glands it is permanent. Sweat glands do not and cannot regenerate. MiraDry is a great option for hyperhidrosis to the underarms.

It appears to be very safe

MiraDry cooling system protects skin during treatment. We have been using hte system for almost 2 years now and do not encountered any of these problems. Satisfaction rate is very high and so far no problems

MiraDry may help tighten the skin

Thanks for your question.  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 sweat glands are located.  Energy at this specific level of treatment does not significantly reach the fat and may actually help tighten the skin.  Studies demonstrate that results last up to 2 years and are likely permanent as sweat glands do not regenerate.

MiraDry is safe and does not cause lipolysis or dermatosclerosis - Buffalo Niagara NY

miraDry is safe and applies microwave energy skin deep (dermis) with no effect on underlying fatty tissue and I have (nor have others) seen any untoward side effects of skin thickening or long lasting scarring or leatheriness of the skin. More likely to have probems with the fatty tissue with the good old fashioned suction curettage or the jerry rigged laser version of suction curettage (SDLA procedure).

Read the miraDry ebook provided on the link below as it has a lot of information about the miraDry procedure. 

No effect from miradry on fat

There is no reports of changes in the fat as the energy is primary directed at the dermis.  I suspect that we will discover that miradry may make the skin in the armpits tighter which may be a positive outcome for many individuals.
