The demand for body contouring, particularly buttock enhancement, has surged in recent years, reflecting evolving societal
beauty ideals influenced by factors such as size, shape, and ethnicity. Modern patients prefer less invasive procedures that
reduce downtime and complications. This pilot study explores the use of a hybrid solution combining calcium hydroxylapatite
(CaHA) and hyaluronic acid (HA) for buttock enhancement, addressing issues such as sagging, cellulite, and contour
irregularities. A pilot study was conducted with four patients who received subcutaneous superficial and deep injections of
the hybrid solution. Results indicated significant improvements in volume and contour, with volumetric increases of up to
835.08 cc, alongside high patient satisfaction and minimal adverse effects. The findings suggest that this individualized
approach effectively enhances buttock aesthetics while promoting skin texture and firmness. Further research is needed to
assess the long-term efficacy of this technique.
