In general, Botox is the brand name for a botulin toxin type A and there are subtypes such as type B variety (BTX-B), known as Neurobloc in the E.U., or Myobloc in the U.S.A. Both are employed in medical and therapeutic purposes. Botox itself is more popularly known for its non-surgical cosmetic function. It is also known as Vistabel in the E.U. and Dysport.
In the 1950s, although experimented with much earlier, very small injections of botulin toxin type A (BTX-A) were used to decrease overactive muscle activity. In that same period, it was experimented with in cosmetic treatments. In 1989, in the U.S., Allergan Inc. got approval from the F.D.A. and named their drug Botox. Approval for its cosmetic use came in 2002 when researchers discovered its cosmetic effects.
Technically speaking, botulin toxin type A (BTX-A) is produced by bacteria. Once processed, its injection interferes with nerve impulses and other things. As such, it has served many purposes in non-surgical cosmetic treatment, namely the removal of lines. However, its effects are not permanent, so future injections may be required.
It has been used to treat glabellar lines (severe frown lines between the eyebrows), excessive underarm sweating, spasticity, muscle disorders, and even obesity. The study of Botox on other treatments remains ongoing.
Botox is usually considered a prescription drug that needs to be administered by a qualified physician. For this reason, it should be done in a controlled setting like a doctor's office. In this way, any possible immediate side effects can be monitored by the administering physician. For this reason, among others, so-called "Botox parties" are not recommended.
Apparently, in the U.S., Botox is licensed for use in single-use vials. In other words, it's prescribed for the use of a single person. The vials cannot prevent contamination if it is repeatedly used for more than one person. However, many individuals aim to lower the cost of the injections and this causes problems.
Unfortunately, the consumption of alcohol in such an environment can negate the effects of the injections. After receiving an injection, one should not rub their face and stand up straight for several hours. Both are meant to prevent the Botox from spreading outside of the targeted area. One of the most commonly known side effects are droopy eyelids. This is because the muscles controlling the eyelids have become paralyzed. However, this side effect is normally considered to last only a few days.
As Botox comes from a neurotoxin, one should take care of its use as in any treatment. You should also consult the physician regarding the required injection frequency. This may be anywhere between four to eight months, but no less than three.
