“Elvis Muscle” snarl, pinches one side only. Issue for many years and have had 3 rhinoplasties. Can it be fixed? (photos)

It's difficult to say without a formal evaluation. Botox can be injected into these areas to create a softer look. The botox will essentially relax the muscles creating the appearance of atrophic muscles. The results will last up to 3-4 months hence you will have to re-inject roughly 3x per year. When administered by an expert injector you shouldn't have an issue with too much laxity. The biggest issue will be muscle weakness if you inject too large doses, which will be required in larger muscles (as compared to cosmetic forehead/face injections) See an expert. Best, Dr. Emer.
