(incobotulinumtoxinA) It is a uniquely purified choice for moderate to severe frown lines and wrinkles. It works by blocking the release of chemicals that cause muscle contractions, so frown lines are then softened. Xeomin® is comparable to the most commonly known Botox®. The difference is that unlike Botox®, which contains accessory proteins, Xeomin® is designed to deliver the toxin without any protein additives. That in turn gives it the name “naked’ toxin.
Treatment is by giving injections into the muscles of mastication. The injection targets the muscle involved with the contraction. Patients with chronic pain have had positive results within a week. Use of night guard is also used in conjunction of masseter injections.
