UltheraBreakthrough non-invasive technology utilizes microwave energy to safely eliminate underarm sweat.

The miraDry System is the result of over 5 years of research and development, including a major long-term clinical study conducted by leading dermatologists across the United States.

Thermolysis of Sweat Glands Provides Lasting Results

The miraDry System delivers precisely controlled microwave energy non-invasively to the region where the sweat glands reside. The energy generates heat which results in thermolysis of the sweat glands. At the same time, a continuous hydro-ceramic cooling system protects the superficial dermis and keeps heat at the level of the sweat glands. Because sweat glands do not regenerate1 after treatment, the results are significant and lasting. Most patients report a dramatic reduction of their sweat – in a recent clinical study,2 the average sweat reduction was 82%.

“Prior to the miraDry procedure, there were limited options available for treating axillary hyperhidrosis, none of which offered a lasting, non-invasive solution.”
Dr. William P. Coleman, III, New Orleans, LA – Dermatologist & Cosmetic Surgeon

The miraDry System provides:

  • A range of energy settings
  • Hydro-ceramic cooling system to protect dermis
  • Vacuum to stabilize tissue
  • Easy to use, custom software that guides procedure

The miraDry System consists of a Console, Handpiece and bioTip. The miraDry bioTip is a sterile, single-patient use consumable that helps ensure safety and efficacy for the patient as well as protection of the equipment.

miraDry Procedure


Straightforward, in-office procedure provides lasting results

Treatment is customized for each underarm with multiple placements of the miraDry Handpiece. The miraDry procedure is non-invasive; it involves no surgical incisions or cuts. Prior to the procedure, temporary markings are placed on the skin to guide treatment, and local anesthesia is administered to the underarms to maintain patient comfort.

The total patient appointment time is generally 60 minutes, with treatment itself taking approximately 40 minutes. Custom software guides you or your staff through the process, making it easy to conduct the procedure. Most patients notice sweat reduction immediately after the procedure. Two procedures are typically recommended three months apart to maximize the results and duration.

“Hyperhidrosis is a serious medical condition that significantly impacts the lives of millions of people. I did not fully appreciate the prevalence of the condition nor the high level of patient interest in a lasting solution until our practice started offering the procedure.” Carolyn I. Jacob, M.D., Chicago, IL – Dermatologist & Cosmetic Surgeon

Strong Safety Profile

Most patients are able to return to work on the same day of the procedure, and can typically resume exercise within several days. All patients will experience soreness under their arms for a few days after the procedure. Mild to moderate edema under the arms is typical post treatment and lasts about a week or two. Some patients have temporary, short-term altered sensation in the skin of their underarms or upper arms, which gradually disappears.

Benefits of miraDry Procedure

  • Lasting efficacy
  • Non-invasive
  • Strong safety profile
  • High patient satisfaction
  • Minimal to no patient downtime
  • Can be performed by Physician Assistant or Nurse Practitioner (state law dependent)

Note: The miraDry System is indicated for use of treatment of primary axillary (underarm) hyperhidrosis in adults 18 and over. It cannot be used to treat hyperhidrosis elsewhere on the body, including the hands and feet.

The miraDry System is contraindicated for patients:

  • With heart pacemakers and other electronic device implants
  • Who need supplemental oxygen
  • With known resistance to or history of intolerance of local anesthesia including lidocaine and epinephrine

How it works

miradry-works11. Focused energy delivery to the dermal-fat interface region

  • Virtually all the sweat glands reside there

miradry-works22. Energy becomes concentrated along interface and creates a Focal Energy Zone

  • Differences in electromagnetic properties in the interface create reflection of energy
  • Energy intensified from constructive interference

miradry-works33. Continuous hydro-ceramic cooling system keeps Heat Zone at level of sweat glands

  • Cellular thermolysis occurs at 55 to 60 degrees celsius
  • No regeneration of sweat glands results in a lasting solution
  • Cooling protects epidermis and upper dermis, while deeper tissue not affected
