Hello, Thank you for sharing your concern. After three years, it is generally possible to address the outward appearance of your philtrum following a lip lift. The options for correction may include surgical revision or non-surgical treatments depending on the specific issues you're experiencing, such as scarring, asymmetry, or dissatisfaction with the overall aesthetic outcome. A detailed in-person consultation with a board-certified plastic surgeon or a dermatologist specializing in cosmetic procedures would be essential to evaluate your case thoroughly. During this consultation, they can assess your current condition, discuss your aesthetic goals, and recommend the most appropriate treatment plan for you. Please ensure you choose a specialist with extensive experience in lip lift revisions to achieve the best possible results.
