Recently, comedian @Hannah Berner shared her experience after developing difficulty smiling following masseter Dysport injections. While uncommon, this is a well-recognized complication that can occur when the neurotoxin affects one of the nearby smile muscles. Unfortunately, there is no reversal agent and no true fix. Recovery simply takes time, typically 2 to 4 months depending on the product used, the dose injected, and the individual. Some people try using the back of an electric toothbrush or a vibrating facial massage device over the affected muscle in an attempt to stimulate it, but there is currently no scientific evidence that this speeds recovery. This is one of the reasons I use ultrasound to map the masseter before every treatment. Not everyone has textbook anatomy. Visualizing the muscle allows me to tailor each injection to the patient’s unique anatomy and helps minimize the risk of affecting nearby smile muscles. #masseterbotox #botoxgonewrong #botox #cantsmile #drbitafarrell
