Botox Information 

Botox is a substance derived from botulinum toxin A which is a neurotoxin that is used clinically in small quantities to treat strabismus and facial spasms and other neurological disorders characterized by abnormal muscle contractions.  Botox is also used by cosmetic surgeons to smooth frown lines temporarily which last for 3-6 months and must be injected again.
History of Botox:
Botulinum toxins were first researched in the late 1960s to treat Neurological disorders. Botox was first approved by the FDA in 1989 to treat eye muscle disorders like blepharospasm, uncontrollable blinking, and strabismus, crossed eyes and even for wrinkles. In 2000, it was approved to treat cervical dystonia which is a disorder that causes severe neck and shoulder contractions and as an unusual side effect of the eye disorder treatment, doctors observed that Botox softened the frown lines between the eyebrows. So, Botox came into existence.
How does it work?
Every time when you smile, laugh or frown wrinkles are caused by contractions of the delicate underlying facial muscles.  Years and years of making these expressions, thus causing a crease in the skin, makes these creases permanent and for this no eye cream or anti-wrinkle cream can smooth out these wrinkles. And hence Botox is injected into the affected area and temporarily paralyzes the muscles so that you cannot make these creases in the skin and due to this you will still have movement which allows you to still look like you, but not enough movement to cause a wrinkle. Taking the Botox treatment, you will look younger.
How much does Botox cost?
Now-a-days many people, both men and women are turning to Botox injections as a method of reversing the effects of time on their skin and turning back the clock and due to its increasing popularity, it has now become the most affordable and effective wrinkle-reducing option available to the average consumer. Botox injections prices vary. The average cost of Botox injections in the United States is $350 and the areas that require single injection such as the area besides the eyes cost $400 to $900. For larger surface areas such as the forehead can cost $600 to $1300 in US.  While in Canada, a single injection can cost from $300 to $500.
