Botox is an FDA approved purified protein which is injected into targeted muscles and temporarily blocks nerve signals that cause muscle movements, essentially relaxing the muscle which reduces or eliminates fine lines and wrinkles.
Within 3-5 days of the Botox injection, the treated facial muscles become temporarily relaxed, causing the overlying skin to lay flat and unwrinkled. The untreated facial muscles contract in a normal fashion allowing facial expressions to be unaffected.
Botox injections only take a few minutes and will remain effective for approximately 3 months. With regular treatments, Botox can help train your facial muscles to reduce wrinkles and facial pain for longer periods of time.
