What is Botox?
Botox is a by-product from the bacteria known as Clostridium botulinum.
It has been purified and when used in small doses produces weakened
muscles. It has been used for many years in treating patients
with muscular diseases where the muscles are in spasm. For the
past 10 years, it has been used in cosmetic dermatology to treat
hyperfunctional facial lines.
What
are hyperfunctional facial lines?
These are expression lines such as frown lines, brow lines, crow
s feet and bunny lines which become prominent with age, sun damage,
and excessive facial muscle activity.
How
does Botox work?
Botox is injected into the muscles of facial expression. This
blocks the muscle from contracting allowing the overlying skin
to become smooth with fewer lines and wrinkles. The untreated
facial muscles contract in a normal fashion allowing normal facial
expression.
