Thank you for your question and for providing a photo for evaluation. Lip filler migration can sometimes occur, especially in the months following the procedure. Given that you had your fillers done 4-5 months ago and this is your first experience with lip fillers, it's understandable that you might be concerned about the appearance and placement of the filler. From your description, there are a few possibilities to consider: Natural Lip Anatomy: Your mention of having a naturally double-lined lip could indeed make it more challenging to determine if the filler has migrated. This anatomical feature might accentuate or create the appearance of migration even if the filler remains in place. Filler Migration: Filler migration typically manifests as a noticeable change in the shape or contour of the lips, often with the filler appearing above the vermilion border (the junction between the lip and the adjacent skin). If you observe a smooth or bulging area above your natural lip line, this could be a sign of migration. Time Frame: It's important to note that filler migration, if it occurs, can sometimes stabilize over time. However, if the migration is significant and bothersome, dissolving the filler with hyaluronidase is an option. Considering the complexity of your situation, I recommend the following steps: Consult with Your Injector: Schedule a follow-up appointment with the practitioner who performed your lip filler injections. They can provide a professional assessment and determine if migration has occurred and what the best course of action would be. Second Opinion: If you're not satisfied with the initial consultation, seeking a second opinion from a board-certified dermatologist or plastic surgeon with experience in lip fillers can be beneficial. Dissolving the Filler: If migration is confirmed and it's affecting your satisfaction with the results, dissolving the filler with hyaluronidase is a safe and effective option. This enzyme breaks down hyaluronic acid fillers and can help restore your lips to their natural state. Ultimately, the decision to dissolve the filler should be based on a thorough evaluation by a qualified professional who can assess your specific situation and provide personalized advice.
