Novel therapeutic approaches with poly-L-lactic acid for treating gluteal skin laxity in male patients

Abstract

Poly-L-lactic acid (PLLA) has become a popular treatment for body skin laxity, especially in female patients; however, research on its use in male patients remains limited, particularly in addressing changes in the gluteal region due to aging. This case report investigates the efficacy of PLLA in treating skin laxity in the gluteal area of three male patients aged 36, 41, and 50 years who were treated at the Antony Barbosa Institute between May 2023 and June 2024. The Male Gluteal Contour Method™: C-Tech Collagen Boost was employed using a C-shaped injection technique with an 18G × 70 mm cannula. Patients underwent four sessions of PLLA injections, reconstituted with bacteriostatic sterile water and lidocaine, at 4–6-week intervals. Improvements in the gluteal contour and skin laxity were noted in all patients, with increased collagen production contributing to enhanced muscle definition and firmness. Minimal side effects such as mild bruising, swelling, and tenderness were reported, and no nodules were observed. This study highlights the importance of tailored treatment plans that cater to the specific needs of middle-age and older men. The C-shaped injection technique allowed for an even distribution of the biostimulator while respecting male anatomy. PLLA is a promising nonsurgical solution for improving male gluteal contour and skin quality, although further research with larger groups is warranted to establish more definitive guidelines for its use in male gluteal augmentation.
