Trending for a little over a year now, some women have been using microwave technology to stop excessive sweating from the underarms and to remove underarm hair. This technology is not the same as laser hair removal and it claims it can be used on all skin colors and hair types to remove hair!

But does this include sweat? Really? Safely? Let’s drive a deeper to see what this is all about.

Microwaving Your Armpits – What Is It?

The Mirasmooth treatment is different than other treatments such as Botox for hyperhidrosis. Mirasmooth works by heating the glands under your arms and destroying the glands thereby preventing the ability to sweat. An anesthetic must be applied before the sweat treatment is done.

Approved by the FDA in July 2015 for use in the United States, the Mirasmooth, made by Miramar Labs; is the first of its kind of hair removal and sweat eliminating treatment. Given that there’s not enough data collected to-date, it’s difficult to say what kind of effects; if any, could come from never sweating again.

However, two possible side effects could be nerve damage due to the extremely intense heat and also perhaps significant swelling after the treatment. To prevent pain and to numb under the arm, an anesthetic is used before the treatment.

What’s A Safe Treatment To Minimize Excessive Sweating?

Well-accepted by men and women, Botox for underarm sweating is effective and safe.

We think that the new Mirasmooth treatment could provide a useful way to reduce underarm sweating and help with hair removal but until more is known about this new treatment then we would avoid it and stick to methods that we know are safe!
