It sounds like you’re experiencing prolonged muscle weakness and cheek drooping after Dysport injections, most likely from diffusion into the zygomaticus major and minor (ZMJ, ZMI) muscles, which are responsible for lifting the corners of your mouth and upper cheeks during smiling. This can result in a flattened smile, asymmetric or incomplete cheek lift, and abnormal recruitment of other muscles (like the platysma, causing neck bulging) when trying to smile or express. Here’s what may be going on: 1. Muscle Over-Diffusion or Incorrect Placement Dysport is known to diffuse more widely than Botox. If it’s injected too low or too laterally near the zygomatic muscles, it can accidentally weaken these smiling muscles, leading to the "cheek drop" effect. This typically resolves in 8–12 weeks, but in rare cases, the weakness can last longer, especially if compounded by multiple doses in close succession. 2. Cumulative Dosing Effect Receiving two full Dysport treatments within 7 weeks may have contributed to the prolonged paralysis. These muscles didn’t have time to fully recover before being re-exposed, potentially deepening the suppression of movement. 3. Platysma Compensation The platysmal band prominence and undereye pulling when smiling are signs of compensatory muscle activity. Your body is using other muscles to try and make up for the weakened smile muscles, which unfortunately can result in unnatural movement patterns. What Can Be Done: Time is still your greatest ally. Even with prolonged cases, muscle strength and facial expression typically return to baseline within 3–6 months. Avoid further neurotoxin injections in or near the affected areas until full function returns. Neuromuscular stimulation therapy or physical therapy (facial massage and facial exercises) may help facilitate recovery. Hyaluronidase (off-label) in some cases is used to break down filler near the affected area if filler-induced pressure contributes to muscle compromise, although your issue sounds strictly toxin-related. Final Thoughts: What you're describing, the indent with smiling, platysma activation, and under-eye distortion, is consistent with zygomaticus paresis from unintended Dysport spread. It is not permanent, and while extremely distressing, there’s a high chance of full resolution with time. Avoid future injections into the lower lateral orbicularis or malar areas, and make sure any future provider adjusts the technique to avoid this complication again.
