What Is Botox?
Botox (onabotulinum A toxin) is a drug that is produced from a protein, also a neurotoxin, from the bacterium Clostridium botulinum. This toxin and its role in the nervous system was identified due to the illness botulism. In cosmetics and medical practice, the protein is purified and used in Botox ® used in medicine since the 1970s. During the last 20 years, Botox has been increasingly exploited and is widely used in dermatology, in addition to the treatment of medical conditions such as migraines and excessive sweating. There are other brands of Botox-like treatment containing the same neurotoxin protein, such as Bocouture.
How Does Botox Work?
Botox works by blocking the activity in the local muscles by preventing the release of neurotransmitter, acetylcholine, at the nerve synapse. Loss of acetylcholine in the neuromuscular junction results in flaccid paralysis due to the prevention of muscle contraction. The result is a more relaxed expression, and it is the weakening of the selected muscle that induces a smoother and flatter appearance in the overlying skin. For this reason, Botox is frequently used to relax facial muscles and reduce facial wrinkles, inducing a more youthful appearance. An experienced clinician will use a tiny needle to inject the Botox into the striated facial muscles. Subsequently, the clinical effect of Botox is usually observed a number of days, post-injection.
