It is a toxin produced by the bacteria Clostridium botulinum. When ingested in large quantity, the toxin causes paralysis of muscles. When injected in very small amount into a particular muscle it causes paralysis of that muscle only. Therefore if it is injected into the small groups of muscles which cause frowning and wrinkling, the frown lines and wrinkle lines will disappear
It is to treat:
The toxin is injected serially into a group of muscle which controls frowning and wrinkling with a very fine needle attached to a small syringe.
When treating frown lines the toxin is injected to a group of muscles just above the eyebrows. The toxin is also injected into a muscle at the bridge of the nose.
When treating crow's feet the toxin is injected serially at several points into the muscles causing the wrinkles at the sides of the eye.
It takes only a few minutes. It is a relatively painless procedure. The patient will experience pain from the needle pricks only.
After the treatment you should remain upright for 3 to 4 hours. During this period you must try to move the muscles that have been injected as much as possible to activate the effect of the toxin on the muscle. Do not rub the skin or muscles on or around the injected site.
The anti-wrinkling effect sets in within three to four days after the injection. By the second week full paralysis of the wrinkling muscle will take place. The anti-wrinkling effect of Botulinum Toxin lasts for three to four months only. There is individual variation. Gradually the wrinkling muscle function returns and wrinkles reappear. When this happens a repeat treatment is necessary to maintain the desired results.
Botulinum Toxin injection is a relatively safe procedure. Side-effects are uncommon. They are usually related to the injection procedure itself. There may be slight discomfort from the needle prick and a small chance of a bruise developing around the injection site. Slight drooping of the eyelids may occur but this is uncommon and transient and usually not noticeable. Transient headaches may occur. No permanent side-effects from Botulinum toxin injection have been reported so far.
