In simplistic terms, the toxin blocks the nerve impulse that controls movement by restricting the patient's ability to contract the facial muscles.
No contraction of the muscles = no movement over the muscle and no movement = no wrinkles.
This smoothening effect may be seen even while the patient is still in the office and improvement continues over the following couple of days, with the results lasting approximately 3-6 months, at which point most patients gradually return to their original state of wrinkling.
Botulinum toxin A,s over 20-year history speaks for itself! But to many people, the word poison or toxin conjures up “ perceived dangers”. Most people do not know that Botulinum Toxin is actually a purified protein with no live bacteria.
Research shows that there are no long-term complications or hazards, a lethal dose injection would consist of 2500-3000 units of botulinum toxin A ( 25-30 vials). BT vial is delivered in 100 units per vial. For patients suffering from muscle spasms associated with cerebral palsy, dosages as high as 1000 units are used routinely, and when botulinum toxin is used for cosmetic purposes, the average dosing is 50-75 units. It is very insignificant, but most importantly extremely safe.
