At Trifecta Med Spa, we offer Botox injection treatment for hyperhidrosis. Excessive sweating, or hyperhidrosis, is caused by the stimulation of the sweat glands by nerve endings which descend from higher centers in the brain. Excessive sweating on the forehead, armpits, underarms, palms, scalp and soles is a common problem that can be very annoying and socially handicapping.Topical treatments can work by reducing sweating in these regions. These products can be irritating with continued use and are ineffective for many people. Oral medications currently used for excessive sweating often provide relief but cause side effects such as dry mouth and blurry vision. Tap water iontophoresis is not very effective and surgical alternatives can cause pain and scarring and may result in permanent skin numbness. Botox prevents sweating for months by blocking the release of the neurotransmitter- acetylcholine, from the nerve endings, that causes the glands to produce sweat. At Trifecta Med Spa in NYC we make 15 to 20 small Botox injections into each underarm which decrease sweating by 90% within 48 hours and usually last from 6 to 10 months.
