Redness and bruising

If you have swelling, then expect to have some redness as well after your miraDry session. There’s also a small risk of developing a rash after your session, but you can ask your provider for a safe remedy if you experience this uncommon side effect.

During the miraDry treatment, you’ll experience an initial stinging due to the local anesthesia injections administered onto your armpits. It numbs your treatment area, although it’s normal to feel some warmth or heat as the microwaves hit your skin.

To prevent the feeling of discomfort during anesthesia injection, your doctor might apply an icepack onto the treatment area before the anesthesia administration.

As for the soreness after the procedure, patients liken it to a mild sunburn. It typically lasts for only a week. Your miraDry provider might also give you over-the-counter painkillers.


Numbness and tingling

It’s common to develop a numbness and tingling sensation in your underarms and upper arms for up to five weeks.

But on rare occasions, this can progress to permanent nerve injury. Patients with a thin build are more susceptible to permanent nerve injury since their nerves sit closer to the surface of the skin.

Not all miraDry side effects are bothersome.

Because miraDry also targets the hair glands in your armpits, you’ll experience permanent hair loss in the area. No need for shaving or waxing that can cause ingrown hairs!

MYTH: miraDry causes cancer

Current studies about miraDry show no evidence that it can cause any cancer.

miraDry only targets the glands directly below the skin, only reaching a depth of 4-5 mm. It does not affect deeper tissues or lymph nodes.
Plus, it uses microwave energy to zap your sweat glands, not radiation treatment.

Remember also that to be approved by the Food and Drug Administration (FDA), the treatment must undergo numerous researches and tests to be deemed safe for use.

MYTH: miraDry can burn your skin

Although burning is theoretically possible, miraDry is equipped with a cooling system to prevent burning over the skin surface.

The technology has been designed to keep the skin as cool as possible.

In the hands of an experienced miraDry provider, you’ll only experience minor discomfort typical of a mild sunburn. It should resolve within a week.

MYTH: miraDry affects your ability to breastfeed

miraDry only focuses on the treatment are in your underarms, so it will not penetrate nearby breast tissues or mammary glands. You should have no problems breastfeeding after the treatment, and it’s perfectly safe to do so.

However, further studies are needed to ensure the treatment’s safety on the fetus and growing baby. It’s always best to err on the side of caution and wait until after pregnancy and breastfeeding to get a miraDry treatment.
