Thank you for reaching out with your concern. Overfilling of the philtrum can sometimes occur with dermal fillers, and there are a few options to consider for correction. Dissolving Fillers: Hyaluronic acid-based fillers can be dissolved using an enzyme called hyaluronidase. This is often the most immediate and effective way to reduce excess volume if the filler used is indeed hyaluronic acid-based. Natural Dissipation: Fillers naturally break down over time. Depending on the type and amount of filler used, you might consider waiting to see if the effect lessens naturally. Consultation with a Professional: It's crucial to consult with a board-certified dermatologist or plastic surgeon who can assess your specific situation. They can provide personalized advice and discuss the potential outcomes and risks of each option. Please make sure to choose a qualified and experienced professional for any corrective procedures. If you have any further questions or need a referral, feel free to reach out.
