Objectives: This study aims to evaluate the safety and durability of the non-surgical high-definition abdominal technique using hyaluronic acid fillers and collagen biostimulators. It also aims to analyze the level of satisfaction of the patients treated, considering aspects such as the naturalness of the results, the time it takes to maintain the effects and any adverse effects. Introduction: The search for more defined body contours has driven the development of minimally invasive aesthetic techniques. High definition of the abdominal muscles, traditionally achieved through high definition liposuction (HD-lipo), can now be achieved non-surgically with the strategic use of hyaluronic acid fillers and collagen biostimulators. This approach aims to enhance muscle definition, providing a more athletic and harmonious contour without the need for invasive procedures. Materials / method: Male and female patients aged between 18 and 42, with a low percentage of panniculus adiposus in the abdominal region and no contraindications to the use of dermal fillers were selected. a synergy between a hyaluronic acid-based dermal filler and calcium hydroxyapatite was used to mimic hypertrophy of the skin and subcutaneous region adjacent to the rectus abdominis muscle. the results were evaluated using photographic documentation, imaging software and high-frequency dermatological USG over a period of 1 year. Patients were also periodically evaluated on their level of satisfaction. Results: The use of the products in the appropriate skin planes and in synergy resulted in high aesthetic impact for the patients, with a satisfaction rate of over 85% over a period of 1 year. satisfactory dermal thickening was achieved with the use of CaHA and the volumization was maintained after the same period, through the observation of HA at the injected site. the safety profile of the procedure was adequate, respecting the execution techniques and the anatomical limits of the abdominal region. no additional intervention was required to manage complications arising from the procedure. Conclusion: The synergy of the association of HA and CaHA has brought a new possibility of non-surgical treatment for the abdominal region, providing results similar to those of lipo-HD. the results are immediate, safe and with progressive improvement over time, but more studies are needed to address the long-term results.
