You may be familiar with the use of laser therapy to treat varicose veins, to perform delicate eye surgery, and to remove skin lesions.

But did you know that lasers are also used to treat excessive sweating (hyperhidrosis) of the underarms (axilla)?

A laser can be focused into a very narrow beam, enabling physicians to target specific body structures without injuring surrounding tissue. This makes laser therapy both powerful and precise – much more precise, in fact, than more traditional surgical tools. The heat from lasers also helps to reduce infection risks and to seal blood vessels to help prevent bleeding. Laser procedures can thus be done faster with quicker recovery than some other types of procedures, and most are performed in a doctor’s office on an outpatient basis – meaning you can go home, or even back to work, soon after your treatment is over.

For the treatment of underarm sweating, lasers are useful in that they can precisely target, heat, and destroy the sweat glands, which are primarily found in a specific layer of tissue under the skin of the underarms. Tiny incisions (often so small they don’t even require a stitch) are made in the underarms to allow the laser tool to be passed under the skin. The procedure usually takes less than an hour to complete.
