Khalaf Bushara and David Park were the first to demonstrate a nonmuscular use of BTX-A while treating patients with hemifacial spasm in England in 1993, showing that botulinum toxin injections inhibit sweating, and so are useful in treating hyperhidrosis (excessive sweating). BTX-A has since been approved for the treatment of severe primary axillary hyperhidrosis (excessive underarm sweating of unknown cause), which cannot be managed by topical agents.
How long the results from a Botox treatment last depends on the dosage and application. If Botox is too diluted and you don't get the proper units of Botox injected, the results might not last very long at all. If you get Botox for the wrong kind of wrinkles (i.e. static wrinkles) or an improper dose for your anatomy, you might not see much improvement either. In general, if the right amount of Botox is injected by a skilled doctor in the right muscles, Botox results can last 3-4 months.
Botox® neurotoxin treatment helps control the symptoms of severe underarm sweating when topical medicines do not work well enough by temporarily blocking the chemical signals from the nerves that stimulate the sweat glands. When the sweat glands don’t receive chemical signals, the severe sweating stops. Botox® injections are expected to temporarily stop the production of excessive sweat in the treated areas only. Sweat continues to be produced elsewhere.
Besides the three primary U.S. manufacturers, there are numerous other botulinum toxin producers. Xeomin, manufactured in Germany by Merz, is also available for both therapeutic and cosmetic use in the U.S. Lanzhou Institute of Biological Products in China manufactures a BTX-A product; as of 2014 it was the only BTX-A approved in China. BTX-A is also sold as Lantox and Prosigne on the global market. Neuronox, a BTX-A product, was introduced by Medy-Tox Inc. of South Korea in 2009;
The range of prices for a single unit of Botox range between $10 and $20 per unit. But the total cost of Botox treatment depends on exactly what you're trying to achieve. For example, the cost of treating horizontal forehead lines may range anywhere from $300 to $700 depending on the factors mentioned above. For other facial areas you may need fewer units.
"There is a difference in pricing based on the duration of the results," says L.A.-based injection specialist Lisa Goodman. (FYI: She's incredible, and I emphatically recommend seeing her if you're in L.A. or Dara Liotta, MD, if you're in NYC.) "The longer-lasting formulas cost more upfront. Shorter-term fillers can last from six to 11 months based on the patient's rate of aging (i.e., smoking, drinking, sun exposure, genetics), while the longer-term fillers last about one to two years."
Focal Spasticity is a condition in which certain muscles in your body become stiff or tight. It is caused by damage to parts of the central nervous system that control voluntary movements. When this happens, your nerves send continuous messages to your muscles telling them to contract, or tighten. If you or someone you care for has stiffness in the muscles of the elbow, wrist, fingers, thumb, ankle, or toes, it could be Focal Spasticity.1
