Introduction: Polymethylmethacrylate (PMMA) is a potent agent that induces neocolagenesis and neoangiogenesis when used in dermal and subcutaneous tissue implantation techniques. In this study, the collagen biostimulation technique with PMMA is presented, with adequate and safe concentrations for facial lifting in different laxity degrees. To present the Objective: PMMA using technique in collagen´s face biostimulation. Material (PMMA) Methods: characteristics, concentrations, suspension technique, injection technique, areas subject to treatment, risk areas and post-treatment assessment in several facial laxity degrees were described. Conclusion: This study described the particularities of the use of PMMA as an effective and potent biostimulator. The technique proved to be effective in treating varying degrees of facial laxity.
