Botox (onabotulinumtoxinA), also called botulinum toxin type A, is made from the bacteria that causes botulism. Botulinum toxin blocks nerve activity in the muscles, causing a temporary reduction in muscle activity. Botox is also used to treat certain eye muscle conditions caused by nerve disorders. This includes uncontrolled blinking or spasm of the eyelids, and a condition in which the eyes do not point in the same direction.
Botox Cosmetic is used to temporarily lessen the appearance of facial wrinkles. It may take only 1 to 3 days after injection before eye muscle spasm symptoms begin to improve. You may notice the greatest improvement at 2 to 6 weeks after injection. Botox injections can be used to weaken or paralyse some of the facial muscles that pull on your skin and cause wrinkles, allowing the skin to flatten out. About 2 to 7 days after the injections, the lines and wrinkles that are normally caused by certain facial expressions start to disappear. Because Botox therapy targets specific, individual muscles, the ability to form most facial expressions should not be affected.
HOW LONG DOES THE EFFECT LAST?
The improvement in the appearance of your wrinkles usually lasts for 3 to 6 months, and repeated injections are required to maintain the effect. With continued use, the effects may start to last longer. A small number of people develop neutralising antibodies to Botox injections after repeated therapy, which results in the treatment no longer being effective.
