Polymethylmethacrylate (PMMA) is a filler introduced to the market as one option for long-lasting treatment. PMMA microspheres are purified, and the particles are larger than 20 μm. The product used as a filler has proven to be safe, effective, and long lasting.OBJECTIVE

Two hundred sixty-six patients (aged 17–72; 154 women) received injections of PMMA to correct facial defects. The number of sessions ranged from one to four, with an interval of 40 to 60 days between applications.RESULTS
Seventy-nine subjects (30%) had facial atrophy related to HIV infection, 159 (60%) had photoaging signs with deep wrinkles and atrophic areas, 25 (9%) had depressive scars from acne process, and three (1%) had residual depressions from lupus profundus. The results were satisfactory and long lasting. Side effects were transient. No late complications were observed.CONCLUSION
