From key trends to fundamental details, get a complete picture of Hannah Berner’s Dysport Mishap Explained: Risks, Recovery, and Safe Jaw Botox Tips in our latest feature.

Chronic jaw tension disrupts sleep, fractures dental enamel, and triggers persistent tension headaches. Berner had dealt with severe bruxism for years. She chose masseter neurotoxin injections, an increasingly popular therapeutic route designed to weaken the bulky chewing muscles that sit at the angle of the jaw.

The procedure works by blocking acetylcholine release at the neuromuscular junction, forcing the hyperactive masseter to soften and shrink over several weeks. Patients routinely seek this procedure for two distinct outcomes: functional pain management and structural jaw slimming. Berner was transparent with her audience that she received Dysport, an abobotulinumtoxinA formulation, rather than standard Botox Cosmetic (onabotulinumtoxinA). While both formulations target the same biological receptors, their molecular behavior and clinical handling differ noticeably in clinical practice.

Within two weeks of her appointment, the comedian observed a stark shift when looking into her camera. Her jaw clenching had subsided, but her dynamic smile had vanished. Only the center of her mouth moved, while the corners stayed flat and immobilized.
