Comparison of 2 Fillers for Lip Injection—A Randomized-Controlled Clinical Trial Assessed by 3D Imaging

Abstract

Abstract BackgroundLip aging is a concern for many, and hyaluronic acid (HA) injections are a popular solution. ObjectivesThis study compared 2 different HA gel technologies (OBT and NASHA) for lip augmentation in 20 volunteers. MethodsBoth groups received treatment from the same injector using the same method. Lip volume was measured with a 3D stereophotogrammetry device before, immediately after, and 30 days posttreatment. Patient satisfaction and adverse events were assessed through FACE-Q scales analysis. ResultsThe NASHA group showed an immediate volume increase (PPPPP ConclusionsThis study highlights that less cohesive gels may modify faster in dynamic lip areas, emphasizing the importance of selecting products based on their physicochemical and rheological properties. In the context of lip augmentation with HA, it is important not to consider immediate aesthetic changes as definitive results, as volume changes may persist and develop over time after the treatment.
