miraDry is a non-invasive treatment for excessive underarm sweating, a condition known as hyperhidrosis. It uses precisely targeted microwave energy to heat and permanently destroy the sweat and odour glands in the underarm, which the body does not regenerate. A single session is usually performed under local anaesthetic and takes about an hour.
Because the glands are removed rather than suppressed, the reduction is lasting, though some people choose a second session to reduce sweating further. The underarm holds only a small fraction of the body’s sweat glands, so treating it does not affect your ability to cool yourself. If you are weighing your options it is worth comparing miraDry against other hyperhidrosis treatments, several of which are temporary and repeated on a schedule. A consultation with a licensed Canadian provider is the next step.


MiraDry™ is a non-invasive treatment for excessive sweating, medically known as hyperhidrosis. It uses thermal energy to target and eliminate sweat glands in the underarms.
Good candidates for miraDry™ depends on various factors, including overall health, medical history, and the severity of your hyperhidrosis. Individuals who are troubled by underarm sweat and/or has been diagnosed with axillary hyperhidrosis (excessive sweating in the underarms) are generally suitable candidates for miraDry™.
MiraDry™ works by delivering controlled thermal energy to the sweat glands in the underarms. The energy heats and eliminates the sweat glands, leading to a reduction in excessive sweating. The treatment is designed to specifically target sweat glands while preserving the surrounding tissues.
Step One – Anesthesia
Maximum comfort is ensured with administered anesthesia during the treatment.
Step Two – Markings
Temporary tattoo markings are prepped onto the skin for the treatment.
Step Three – Treatment
The inked area is treated with miraDry™ for sweat-reduced odorless underarms.
The miraDry™ treatment takes approximately one to two hours depending on an individual’s body type.
Most patients describe the procedure as painless with little to no downtime. Local anesthesia is administered to the underarms prior to the treatment for patient comfort. Patients can typically resume regular activities, including work, immediately. Exercise is typically resumed within several days. Some common post-treatment effects may include swelling, numbness, bruising, and sensitivity in the underarm area, which usually subside within several days.
As with any aesthetic treatment, the results from miraDry™ may vary. Some individuals may experience a reduction in sweat production immediately after the treatment, while others may notice gradual improvement over time. The full effects are typically seen within a few weeks to a couple of months after the procedure.
The results of miraDry™ are considered long-lasting. The treatment permanently reduces the number of sweat glands in the treated area, leading to a significant reduction in excessive sweating. However, it’s important to note that individual results may vary.
The cost of miraDry™ in Canada can vary depending on various factors, such as the location, the provider, the number of treatment sessions required, as well as the severity of the cosmetic issues being addressed. It is recommended to consult with a miraDry™ provider or clinic directly to inquire about the specific cost.
As with any medical procedure, miraDry™ does carry some risks. Potential risks and side effects may include:
Temporary swelling.
Soreness.
Bruising.
Numbness.
Altered sensation in the treated area.
In rare cases, there may be prolonged or excessive swelling, infection, or changes in the skin.
Both treat excessive underarm sweating, but they work differently and last for different lengths of time. Neuromodulators such as Botox block the nerve signal that switches sweat glands on, which reduces sweating for roughly four to six months before the injections need repeating. miraDry destroys the glands themselves, so a single treatment is intended to be lasting rather than repeated on a schedule. Injections are quicker and need only topical numbing, while miraDry is a longer appointment under local anaesthetic with more swelling afterwards. Which suits you depends on whether you would rather maintain a lower-commitment treatment or have a one-off procedure, and that is worth discussing with your provider.
