Background
Minimally invasive body‐contouring procedures continue to increase in popularity as patients seek natural‐appearing enhancement with reduced downtime. Calcium hydroxylapatite‐carboxymethylcellulose (CaHA‐CMC; Radiesse) is a biostimulatory filler with established safety and effectiveness across approved facial, décolleté, and hand indications, and emerging evidence suggests potential benefit for improving buttock contour.
Aims
To develop a global expert consensus outlining best practices for the use of CaHA‐CMC in buttock augmentation, including guidance on patient selection, aesthetic assessment, injection technique, safety considerations, and treatment planning.
Methods
An international, multidisciplinary panel of aesthetic experts convened to develop consensus recommendations for CaHA‐CMC in buttock augmentation. Published clinical evidence was summarized, supplemented with real‐world expert experience, and recommendations were refined through interactive panel discussion.
Results
Experts agreed that available evidence and clinical experience support the safe and effective use of undiluted and diluted CaHA‐CMC for buttock augmentation when administered by trained practitioners. Key recommendations include prioritizing contour correction over volumization; using a 1:1 CaHA‐CMC: saline dilution for optimal distribution and biostimulation; administering treatment across three sessions; and employing cannula‐based techniques with anatomically mapped injection zones. Across available studies and clinical experience, CaHA‐CMC produced consistent aesthetic improvements with a low incidence of adverse events.
Conclusion
This global consensus provides practical, evidence‐informed guidance for CaHA‐CMC‐based buttock augmentation. Available evidence suggests that when applied with appropriate practitioner training and patient‐centered planning, CaHA‐CMC has a favorable safety profile and yields natural‐looking, reproducible improvements and predictable results in buttock contour. Standardized protocols and continuing outcomes research will further refine clinical practice.
