Botulism Toxin Type A also known as Botox® is a proprietary drug now used for the improvement of facial animation wrinkles, lines, and creases. Botox temporarily paralyzes the muscles around the wrinkles, causing them to disappear. This medication has been used for many years for blepharospasm (bleff-UH-row-spaz-m), a condition that affects the eyelids. In 2002 the FDA (F-D-A) approved Botox® for injection into the facial skin of the forehead to eliminate forehead frown furrows. Doctors also use Botox® around the eyes to reduce the wrinkling known as crow's feet and around the mouth to reduce “smile lines.” It has even been used to reduce the prominent appearance of the anterior pillars of the neck due to laxity of the platysma (pluh-TIZ-muh) muscle, and to lower the upper lip line for those people who are concerned by a 'toothy' smile showing too much gum. While Botox® produces satisfactory results for most patients, it is not a permanent treatment and must be repeated for maintenance of appearance. Botox® can achieve results that are impossible to achieve through surgery. Side effects include headache, pain at the injection site, redness and muscle weakness.
