What is Botox®?
Botox®
is a purified protein toxin produced by the clostridium botulinum
bacteria. Although Botox®
is a toxin, there have been no serious side effects. This is
because, for the treatment described, it is used in extremely small
amounts and does not spread throughout the body.
How is Botox®
Used?
A few drops of Botox®
are injected with a tiny needle into the muscle that creates a
wrinkle. When Botox®
is injected into a muscle, it blocks the nerve impulse from reaching
that area, and as a result, the muscle weakens. As the muscle
weakens, the skin overlying the muscle relaxes and the wrinkles
gradually soften and often disappear.
Is the Injection Painful?
When Botox®
is injected there is an initial minor sting for a few seconds. When
the injection is complete, there is usually no discomfort.
Where can Botox®
be injected?
The most common areas for the use of Botox®
are the frown lines between the eyebrows, the horizontal forehead
lines, and the crow's feet. On occasion, other areas may be treated
as well.
