Botulinum toxin is an endotoxin secreted by the bacterium Clostridium botulinum, so it is also known as botulinum endotoxin. Since it is called a toxin, the main concern must be how toxic is botulinum toxin? Will it have side effects on the human body like other drugs? Arsenic is feared to be a highly toxic drug in people’s minds, but in fact, it is far less toxic than Botox. According to research, 1 microgram of botulinum toxin can kill a person, which means that 1 gram of botulinum toxin is enough to poison one million people. For this reason, Botox is also known as the king of poisons. In the early days, this toxin was also used as a biochemical weapon. The mechanism of action of botulinum toxin is complex: it acts on the endings of cholinergic motor nerves, antagonizing the action of calcium ions at the nerve endings and interfering with the release of acetylcholine from the motor nerve endings, thus preventing the muscle fibers from contracting. In short, Botox works by paralyzing the muscles so that they cannot contract. Then the manufacture of biochemical weapons is to use this property of botulinum toxin to inhibit the human respiratory muscles and suffocate them to death. And used in cosmetology, it is to stretch the tense facial expression muscles to achieve wrinkle removal, or paralyze the bilaterally hypertrophied bite muscles of the face to cause disuse atrophy (just like a paralyzed patient’s leg keeps not walking, it will become thinner and thinner), and eventually achieve a thin face. The botulinum toxin used in biochemical weapons and medical cosmetics is the same substance, the only difference is the dose is different. In fact, the current clinical use of botulinum toxin have been diluted nearly 400,000 times, and the amount of each bottle is very, very small, so the toxicity is greatly reduced, research shows that the toxicity of each botulinum toxin is less than 5% of the human poisoning dose. That is to say, theoretically, if 20 successive injections of botulinum toxin (100 units a piece) are given in a short period of time, only then may poisoning occur. Clinically, it is often not recommended to inject more than 5 doses of Botox in a short period of time. For 95% of patients, one or half Botox is sufficient for facial wrinkle reduction or face slimming. Moreover, Botox is metabolized by the human body and will not remain, not to mention causing any after-effects or toxic side effects to the human body, so it is absolutely safe! After nearly 30 years of clinical development and application, Botox injection treatment has also become the most popular cosmetic item in the world approved by the FDA!
