Botox is the trade name for botulinum toxin, which is available in pure protein form. Botulinum toxin A is the most widely used form with several thousand articles documenting its use in the scientific and medical literature.

It is injected into the facial muscles and attaches to the nerve endings of the motor muscles within a few hours, thereby affecting neurotransmission to these muscles.
It takes two to ten days to block the nerve transmitters that innervate the muscles where they are injected. As long as botulinum toxin A is effective, there is no loss of sensory perception at all. Once these motor nerve endings are severed, the muscle can no longer contract.
If the muscles do not contract, the dynamic movements that cause wrinkling of the skin stop. The only reason wrinkles appear on the skin is mainly because the muscles are moving underneath, which is why they are known as dynamic wrinkles.
About three to ten days after treatment, the skin over these motor muscles becomes nice and smooth. The effects of botulinum toxin last for approximately three to four months, depending on various factors including the amount of botulinum toxin A injected, the patient’s metabolic activity, and lifestyle choices, which may prevent botulinum toxin treatment from taking a long time.
If the patient sees the wrinkles reappear, the patient should be treated again. This is one of the reasons Botox has such an outstanding safety record. Botulinum toxin treatment is basically a temporary treatment, and when the healing effects wear off, they go away completely.
