Botox injections are a diluted form of botulism which is injected into facial muscles to paralyse or weaken the muscles that form wrinkles. Botulinum toxins were first researched in the late 1960s to treat neurological disorders. Botox was first approved in 1989 to treat eye muscle disorders (blepharospasm, uncontrollable blinking, and strabismus, crossed eyes).
In 2000, it was approved to treat a disorder that causes severe neck and shoulder contractions. As an unusual side effect of the eye disorder treatment, doctors observed that Botox softened the frown lines between the eyebrows.
Wrinkles that are caused by muscle contraction, such as frown lines, crow's feet, forehead creases, and neck bands can be safely and successfully treated with Botox. You will be asked to contract the facial muscles (frowning, squinting) that affect the area to be treated. This will help to determine the best location for the injection. The injection is normally injected directly into the muscle with a tiny needle.
Results are normally seen within a few days. The results generally last 3-4 months and require occasional touch ups.
