MiraDry emits electromagnetic energy into the underarm treatment area, using a hand piece treated repeatedly into the numbed area. The device vacuums the skin and stabilizes it into place, which brings the sweat glands closer to the surface. The system then administers focused electromagnetic energy through the skin, deep into the region where the sweat glands reside. No incisions are made throughout the process. A cooling system is simultaneously released to protect the skin and help keep the heat energy at the same temperature as the sweat glands. The heat ultimately ablates the glands that cause the excessive sweating.
Destroying sweat glands does not mean the body will struggle or lose its ability to cool itself down because underarm sweat glands account for only two percent of the body’s sweat glands. Excessive sweating occurs when overactive sweat glands produce more sweat than is necessary to cool the body. Sweating is a natural and necessary bodily function used to cool off and get rid of excess heat from working muscles and warm temperatures. In fact, the human body has over four million sweat glands, which can be found virtually anywhere on the body except the lips.
There are two different kinds of sweat glands. The most common sweat gland is the eccrine glands, which cover most of the body, but are concentrated in the hands, feet and forehead and secrete clear, odorless sweat glands controlled by the hypothalamus. These glands are primarily activated by emotional stimuli and stressors that increase the body’s temperature. When the body’s thermoregulation system fails to proportionately excrete and distribute sweat for cooling, many suffer from stained clothes and complications in social and professional interactions. The apocrine gland develops during puberty and is triggered by a secretion of adrenaline, controlled by the adrenal medulla. Apocrine sweat is composed of protein and carbohydrates, which has been known to cause odor because it can come into contact with healthy bacteria on the skin.
