BACKGROUND: Poly-L-lactic acid (PLLA) is increasingly used for a range of indications, from HIV lipodystrophy to gluteal augmentation; however, there is no clear consensus on appropriate product preparation and use. OBJECTIVE: To establish current practices for PLLA reconstitution and usage in the USA. METHODS AND MATERIALS: A 19-question survey pertaining to the reconstitution and use of PLLA was distributed to members of the American Board of Cosmetic Surgery and American Board of Facial Cosmetic Surgery and at several cosmetic conferences. 410 questionnaires were returned anonymously over a 3-month period. The results were collated and analyzed. RESULTS: The commonest indication for PLLA was HIV lipodystrophy (46.8%), followed by gluteal augmentation (42.4%). For the face, the majority used a dilution of 9-10 mL (60.4%). For the gluteal region, the majority used a dilution greater than 21 mL (51.3%). Most respondents reconstituted PLLA in sterile water (59.8%) more than 21 hours before use (51.0%) and added lidocaine to the solution (94.7%). Most physicians used topical anesthetic cream (83.2%), manual agitation (85.8%) and recommended self-massage post-treatment (99.6%). CONCLUSION: There is considerable variation in PLLA reconstitution and use. Further well-designed studies are needed to establish the safest, most effective ways to use this product.
