Expert Recommendations on the Use of Injectable Poly-L-lactic Acid for Contour Deficiencies of the Buttocks

Poly-L-lactic acid (PLLA) is an injectable biodegradable biostimulator that promotes collagen production and is approved for use in aesthetic facial augmentation. PLLA is well tolerated with minimal downtime and has demonstrated an excellent safety profile, as well as a longevity benefit of at least 2 years following injection. The robust safety and efficacy profile associated with PLLA for facial rejuvenation has resulted in a growing interest in the use of PLLA for other body areas such as the buttocks, which are an increasingly popular target of aesthetic enhancement. Patient goals for gluteal enhancement include improving contour and texture, reduction in visible cellulite and increased volume and lift. In order to achieve optimal outcomes and patient satisfaction, it is essential to ensure correct usage of PLLA; however, there is currently a lack of guidelines and expert recommendations in this area. This report reflects consensus recommendations for the use of PLLA in non-invasive buttock contouring, including patient selection, PLLA preparation, dosing, injection and, efficacy and safety assessments. Recommendations were provided by the collective author group, comprising international leaders in the field of aesthetics, dermatology, and plastic surgery.
