What is botox?Introduction
Botox is a trade name for botulinum toxin. Botulism is a form of food poisoning that occurs when someone eats something containing a neurotoxin produced by the bacterium Clostridium botulinum. Botulinum toxin A is one of the neurotoxins produced by Clostridium botulinum. The most serious symptom of botulism is paralysis which in some cases has proven to be fatal. The botulinum toxins attach themselves to nerve endings. Once this happens, acetylcholine, the neurotransmitter responsible for
triggering muscle contractions, cannot be released. A series of proteins, VAMP, syntaxin and SNAP-25, are essential for the release of acetylcholine. Certain botulinum toxins attack these proteins. Botulinum toxin A (Botox) affects the SNAP-25.
Basically, the botulinum toxins block the signals that would normally tell you're to contract. Say, for example, it attacks the muscles in your chest -- this could have a profound impact on your breathing. When people die from botulism, this is often the cause -- the respiratory muscles are paralyzed so it's impossible to breathe.
Botox in the cosmetic industry
Botox was first approved in 1989 to treat two eye muscle disorders--uncontrollable blinking and misaligned eyes. In 2000, the toxin was approved to treat a neurological movement disorder which causes severe neck and shoulder contractions which are known as cervical dystonia. As an unusual side effect of the eye disorder treatment, doctors observed that Botox helped in softening the vertical frown lines between the eyebrows that tend to make people look tired, angry or displeased.
Botulinum Toxin Type A (Botox Cosmetic) is a protein complex which was produced by the bacterium Clostridium botulinum, which contains the same toxin that leads to food poisoning. When used in a medical setting as an injectionable form of sterile, purified botulinum toxin, small doses block the release of a chemical called acetylcholine by nerve cells that signal muscle contraction. By selectively interfering with the underlying muscles' ability to contract, existing frown lines are smoothed out and, in most cases, are nearly invisible in a week.
Conclusion
While the effects of Botox Cosmetic do not last for long but people don't seem to mind repeating the procedure every four to six months in order to maintain a wrinkle-free look. Battling the signs of aging in a non-invasive way, after all, is part of the allure of the product and the fact that there are no unsightly scars, and that there is very little recovery time with the procedure makes it worth.
