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 very safe and effective; the treatment has been performed tens of thousands of times.  The drier armpits result in less irritation from excess moisture and less odor.  The treatment does not affect the fat or the overlying skin.

Yes, having miraDry FDA cleared for permanent reduction of sweating, the treatment has been used in over 55,000 cases worldwide with an excellent safety record. The sweat glands in your under arms are only 2% of your whole body's sweat glands.

Miradry is Safe and Permanent

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
miraDry has been performed on over 50,000 people.  It uses microwave energy to kill the sweat glands and odor glands in the underarm.  It is FDA-cleared for permanent reduction of sweating.  It does not injure the nerves or lymph nodes in the underarm.  

There are about 2-3 million sweat glands on the body and only about 2% of those are found in the underarm.  Therefore, killing the sweat glands with miraDry does not affect the body's ability to regulate its heat and cool off by sweating.

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

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

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