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. Examples include: Cervical dystonia, Lazy eye, Muscle contractures, Hyperhidrosis, Chronic migraine, Bladder dysfunction, Eye twitching.

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.
