Hello, Thank you for your inquiry. Achieving definition in your core depends on several factors, including your current physique, aesthetic goals, and the specific areas you wish to target. Lipo 360, which involves comprehensive liposuction around the entire midsection, can certainly help improve overall body contours and reduce excess fat. While it can enhance your physique and provide some degree of abdominal definition, it may not necessarily result in the sculpted appearance typically associated with a well-defined "six-pack." Abdominal etching, on the other hand, is a specialized form of liposuction designed to precisely sculpt the abdominal area and create the appearance of muscle definition. By selectively removing fat deposits around the abdominal muscles, etching can enhance the visibility of underlying muscle contours and achieve a more athletic appearance. Considering your BMI and the desire for enhanced core definition, you may benefit from a combination approach. Lipo 360 can address excess fat deposits around the midsection, while abdominal etching can further refine the contours and highlight muscle definition in specific areas of the abdomen. During a consultation with a board-certified plastic surgeon, you can discuss your aesthetic goals and explore the most suitable options for achieving the desired results. Your surgeon can assess your candidacy for both lipo 360 and abdominal etching based on your unique anatomy, BMI, and aesthetic preferences. I hope this information helps guide your decision-making process. If you have any further questions or would like to schedule a consultation, please don't hesitate to reach out. Sincerely, J. Timothy Katzen, MD, FASMBS, FICS Plastic and Aesthetic Surgeon
