Botulinum toxin injections with Botox, Dysport or Xeomin preparations are one of the most common methods of non-surgical skin rejuvenation and getting rid of wrinkles in modern cosmetology. After injections of the drug, the impulse from the nerve endings to the muscles is blocked, as a result of which the muscle becomes immobile, but, as before, it continues to be supplied with blood and all the necessary substances. As a result, deep and fine wrinkles are smoothed out.
