Botox injections block certain chemical signals from nerves, mostly signals that cause muscles to contract. The most common use of these injections is to temporarily relax the facial muscles that cause wrinkles in the forehead and around the eyes. Botox injections are also used to treat conditions that affect how the body functions.
Botox injections usually begin working one to three days after treatment. Depending on the problem being treated, the effect may last three months or longer. To maintain the effect, you'll need regular follow-up injections.
Botox must be used only under a doctor's care. It's important that injections be placed precisely in order to avoid side effects. Botox therapy can be dangerous if it's administered incorrectly. A skilled and properly certified doctor can advise you on the procedure and help determine if it best suits your needs and health.
