Botulinum toxin, also known as botulinum endotoxin, or BOTOX, is a bacterial endotoxin secreted by the deadly bacterium Clostridium botulinum. It is highly toxic and is a powerful, irreversible, lethal neurotoxin. It is also a strong muscle relaxant. When injected into the neuromuscular junction, botulinum toxin inhibits the release of acetylcholine from the synapse and causes muscle paralysis. Botulinum toxin acts on the endings of cholinergic motor nerves, antagonizing the effect of calcium ions in some way, interfering with the release of acetylcholine from motor nerve endings, so that muscle fibers cannot contract, resulting in muscle relaxation to achieve the purpose of wrinkle reduction and beauty, and the greater the toxicity, the better the effect of wrinkle reduction and beauty, but microinjection into the skin can be anti-wrinkle. The reason why wrinkles are created is the repeated contraction of muscles, forming the texture of the skin. And Botulinum toxin type A is a type A toxin secreted by Clostridium botulinum in reproduction, which is a neurotoxin and a toxic protein. It is a very important and important part of the process. It has the advantages of little damage, no trauma, no interruption of work, and quick results. Only one injection of Botox is needed at the wrinkles, and the wrinkles will be gradually smoothed out after 3-14 days. However, botulinum toxin is a toxin after all, and it eliminates wrinkles by paralyzing the muscles so that they have no ability to contract, so it may occasionally produce adverse reactions such as headache, allergy, double vision, and unnatural expression. Moreover, Botulinum toxin A is a highly toxic drug, which can be fatal if injected in excess. Cosmetic wrinkle removal injections of Botulinum toxin A only use 25-50 units, which is 3% of the lethal amount of people, which is a tiny dose. ”Botox” wrinkle removal is applicable to: 1, injection treatment of forehead lines 2, injection treatment of interbrow lines 3, injection treatment of crow’s feet 4, injection treatment of broad neck muscle lines
