Had Botox by facial plastic 1/25. Couldn't smile for 2-3 months. Cheeks tight, shelving on cheeks, cheek bone area flat, smile not lifting, def. Not as tight now but still droopy cheeks. Been 6 months. Two in person second opinion said zygomaticus weakened. When I smile cheeks are lower on face and like round balls. See pictures. Shelving is still there but lips turning up now. Is the muscle too weakened to lift past the "shelf". They are like indents. Should I see a neurologist?
