Neuromodulators  are prescription injectable medications that are used to temporarily improve wrinkles and lines on the face.   They are injected in to specific muscles and work by blocking nerve impulses to the muscles that cause wrinkles.  These are the wrinkles that develop because of our day-to-day facial expressions: frown lines, "crows feet" at the corners of the eyes and horizontal lines on the forehead. They have also been used to elevate the eyebrows or to correct a square jaw.

Botulinum toxin was first approved for cosmetic use in Canada in 2002.  Injection sites, quantity of medication used, and number of injections should be chosen carefully in order to achieve the desired effect.  Results typically last 3-4 months.  Repeat treatments may be necessary to achieve optimal results.
