Effectively Fighting Improved Armpit Perspiration with MiraDry


Summer has finally arrived and with them several issues that appear or worsen any given person’s summer experience, including excessive sweating. The hotter the temperature, the higher the body’s temperature. Because of this, cosmetic dermatology has had its hands full trying to fight excessive sweating.

Fighting sweaty armpits

Sweating is a reflex response that regulates body heat. Exercise, stress, and feelings of anxiousness are aggravating factors. Sweat is produced by sweat glands, especially in areas such as the armpits, palms, soles of the feet and forehead.

In some people, this system is deregulated, resulting in an overproduction of sweat. This is called excessive sweating, which can cause serious physical and social discomfort. Today, scientific and technological progress makes it possible to combat this problem effectively.

A safe and effective procedure has been approved by the FDA: MIRADRY, the solution to armpit sweating.

How the system works

MiraDry is a simple, effective and durable technology that every dermatologist should consider. Using a tip positioned in the armpits, the device delivers microwaves to overheat the sweat glands. The associated cooling system protects the superficial dermis and makes the technique non-invasive.

Thus, the glands responsible for transpiration are safely eliminated without pain. An average of 2 sessions should be planned although one session may be sufficient (depending on the expectations of the patients). At present, the technique has been validated for armpit sweating.

However, studies on the treatment of hyperhidrosis with MiraDry are ongoing and the results may vary. People interested in this procedure should speak with their local miraDry dermatologist for more details.


Other techniques can be used to remedy excessive sweating of the armpits: aluminum salts-based antiperspirants, iontophoresis, Botox, and even surgery. Advantages consist of:

Results that last at least up to 5 years

An almost immediate result after the session

High safety of use (FDA approved procedure)

90% of patients are satisfied with results

Less painful than Botox injections


Because the body’s sweat glands do not regenerate, the result is significant and lasts at least an average up to 5 years after treatment. The result is fast and noticeable (a few days). Most patients report a significant reduction in sweating that changes their lives.

In a recent clinical study, the average reduction in sweating was 82%.
