Background
There are two categories of facial wrinkles: static and dynamic.
Static wrinkles are visible when your face is at rest and occur during
the aging process because of the loss of elastic tissue. Dynamic wrinkles
appear temporarily when a muscle contracts during facial expression
(i.e. smiling, frowning). Dynamic wrinkles are commonly found in areas
of facial expression like the forehead (worry lines), between the eye
brows (glabellar lines), and around the eyes (crow's feet).
BOTOX® Cosmetic diminishes or even eliminates the appearance of
dynamic wrinkles because it paralyzes the underlying muscle causing the
wrinkle. When injected directly into the muscle, the purified Botulinum
toxin type A prevents the muscle from contracting by blocking the
transmission of nerve impulses to the muscle. Because the muscle cannot
contract, the wrinkle cannot form and as a result it gradually
diminishes.
BOTOX® Cosmetic is not as effective on static wrinkles which are better
treated surgically or with dermal fillers.
BOTOX® Cosmetic is mainly used to treat dynamic wrinkles in the upper
third of the face although many physicians use it to cosmetically treat
other areas of the face and neck. Moreover, BOTOX® Cosmetic has also been
used to treat migraine headaches and excessive underarm sweating.
BOTOX® Cosmetic Injection
BOTOX® Cosmetic is injected directly into the muscle which causes
the dynamic wrinkles. A very small needle is used to minimize discomfort
and the injection feels like a small prick accompanied by a little stinging.
The entire procedure takes about 10 minutes and since the procedure is
non-surgical, no recovery time is needed so patients can immediately
return to work or other activities.
How BOTOX® Cosmetic Works
The BOTOX® Cosmetic enters the nerve endings and blocks the release of
acetylcholine, a chemical that causes muscles to contract. The paralysis
takes 1 to 5 days to occur and peaks in two to four weeks with results
lasting from three to six months. Because the effect gradually wears off,
allowing the dynamic wrinkle to return, follow up treatments are necessary
to maintain the desired result. Repeat treatments may lead to improved
results as the muscle causing the wrinkles becomes less responsive over
time, a process called chemical denervation.
BOTOX® Cosmetic Side Effectss
BOTOX® Cosmetic can't be used if there is an infection at the proposed
injection site(s) or in individuals with known hypersensitivity to any
ingredient in the formulation (the milk protein Casein). Also, patients
with neuromuscular disorders such as Myasthenia Gravis and Eaton Lambert
Syndrome may be at increased risk of clinically significant systemic
effects from typical doses of BOTOX® Cosmetic. The most common side
effects are headache, respiratory infection, flu-like syndrome,
temporary eyelid droop, and nausea. Less frequently occurring (<3%)
side effects include facial pain, injection site redness, and muscle
weakness. These events are thought to be associated with the injection
and occurred within the first week.
