From the Oscars to the Brits, the past couple of weeks have been crammed full of award shows, and while the idea of stepping out onto a red carpet might with a hundred camera flashes popping in your face might fill most of us with abject horror, A-listers never seem to break a sweat. Literally.
While Botox is most commonly associated with smoothing frown lines and stopping crow's feet in their tracks, the injectable can also be used to stop excessive sweating.
“Botox works by blocking the release of a neurotransmitter (Acetylcholine) that is responsible for the stimulation of the sweat gland,” says Dr Dany Kayle, Founder of Dr Kayle Aesthetic Clinic, Dubai. “Multiple injections are given just under the skin, spaced apart by few millimeters, until the whole target area is covered. Once injected, the Botox will act locally on the nerve endings that are related only to the sweat glands in that area and ultimately prevent their excretion.”
The area most commonly treated are the underarms, but this treatment can be used in any area that “experiences excessive sweating,” says Dr Faisal Salim, Plastic, Reconstructive, and Cosmetic Surgeon at Euromed Clinic Dubai. “This can include the palms of the hands and the soles of feet. The injections can take up to two weeks to work but the effects last about 6 months.”
But that doesn’t mean other areas that haven’t been treated will sweat excessively instead.
“Because we excrete sweat from the entire body’s skin surface, and the armpits, palms of the hands, soles of the feet, the forehead; or indeed whichever area is treated; only constitute a small portion of the whole body’s skin surface area," Dr Kaye adds. "The body will still sweat from the remaining untreated skin efficiently, even if we stop sweating from those areas.”
