Fresh and Sweat-Free

Many individuals are bothered by excessive sweating, and it can be so serious that it affects one’s everyday life. This is why Grossman Dermatology provides miraDry treatments. miraDry is the first and only FDA-approved, non-invasive treatment to stop underarm sweating and odor. It’s a procedure that utilizes controlled electromagnetic energy to destroy sweat and odor glands of the underarms. 

Candidates for miraDry

If you’re in the Santa Monica or NYC area and you’re considering miraDray, you should be aware of who makes the best patient for this treatment. Those who are ideal candidates for miraDry are those who:

  • Experience excessive underarm sweat and odor
  • Constantly feels sticky, smelly, or unclean 
  • Chooses to wear black or jackets to hide sweat marks
  • Understands the miraDry procedure


Performed by Dr. Grossman in NYC and Santa Monica, miraDry is done with a local anesthesia. You will need to shave your armpits 1-2 days prior to a procedure to allow for ease of treatment. If you have not shaved, we may do it for you.

You will be lying down on your back for the procedure, with your arms positioned above your head on a special support. At the start of each miraDry procedure, the staff will mark the skin of your underarm with markers or temporary ink. Injectable anesthetic will be used to numb the area prior to the procedure. 

When the anesthetic is injected, you may feel a pinch or stinging sensation with each injection. Once the area is numb, Dr. Grossman will place the miraDry device on your underarm skin in the marked area. Once the device is positioned, the miraDry system will be turned on. You will feel suction of the skin, and you will also hear beeps and tones that indicate that the energy is being delivered. This will be repeated multiple times. A cooling feature will protect your surrounding skin and tissues from overheating during treatment. If you begin to feel significant discomfort or pain during the procedure — either in the treatment area or your arm — please alert your operator immediately. Once the sweat and odor glands have been destroyed, they will not regenerate. 


The following are common side effects associated with miraDry. These can last between a few days to few weeks (unless otherwise noted):

  • Swelling in the treated area
  • Temporary altered sensation or tingling in small areas of the treated skin or upper arm (can last for several months)
  • Discomfort, tenderness, or pain in the underarm when touched (treatable with over-the-counter medications)
  • Redness from the device suction
  • Bruising or numbing at the injection sites
  • Bumps under the treated skin (can last for several months)
  • Partial underarm hair loss (may be long-lasting)


You will typically see a reduction in underarm sweat immediately after one procedure, but two procedures are required to achieve a 90% reduction of sweat and maximize the results and duration. 

These treatments should be spaced no less than three months apart. Patients who underwent this procedure in a study continued to show a dramatic reduction of sweat when tracked 12 months after the procedure. Like any other medical procedure, results can vary from patient to patient, so be advised that large reductions may not occur in every single case.
