Hello, Thank you for your question and for providing a photo. It's not uncommon for patients to experience unevenness or lumps after cheek filler treatments, even after some time has passed. This could be due to a variety of reasons including asymmetrical filler placement, migration of the filler, or natural differences in facial muscle movement. Here are a few suggestions to improve the appearance: Consult with a Dermatologist or Aesthetic Specialist: A professional can assess whether the lump and flattening are due to residual filler, muscle movement, or other factors. They may suggest treatments such as hyaluronidase injections to dissolve any remaining filler if it is deemed the cause. Consider Additional Filler: Sometimes, correcting asymmetry may involve adding more filler to balance out the appearance. This should be done cautiously and by an experienced injector. Facial Exercises: Some patients find that certain facial exercises can help improve muscle tone and symmetry over time. However, this should be discussed with a professional to ensure it won't exacerbate the issue. Non-Surgical Treatments: Options like radiofrequency or ultrasound therapy can help tighten and lift the skin, potentially improving the overall appearance. Surgical Options: In rare cases, surgical intervention may be recommended to correct significant asymmetry or lumps. It's essential to have a thorough evaluation by a qualified professional to determine the best course of action tailored to your specific situation.
