Botox is the most popular minimally invasive cosmetic treatment on earth. In 2018, 7,437,378 people had Botox treatment, an increase of 845 percent over the number of people who had it in 2000. Besides of its cosmetic uses, Botox is also used medicinally to treat muscle spasms that cause the pain of cervical dystonia, the discomfort of uncontrollable blinking and other health problems.
Information. The botulinum toxin type A is derived from the same Clostridium bacteria that produces the deadly botulism toxin. In the case of Botox, the toxin is purified and extremely diluted and is very safe in the hands of a trained professional aesthetician or dermatologist. It works by interrupting the signals of acetylcholine, which is a neurotransmitter. One of the tasks acetylcholine has is to control the contractions of muscles. Scientists discovered, by accident, that when the botulinum toxin is injected into a muscle beneath a wrinkle or line, the muscle is paralyzed and the line smooths out. The effect can last for up to a year, and in some patients, the wrinkle never returns to being as deep as it was.
