Universal Lip Integrity, Proportion, and Structure: A Framework for Achieving Consistent, Natural-Looking Lip Augmentation Using Hyaluronic Acid Fillers

The authors of this study present a standardized approach for achieving consistent, natural-looking lip augmentation using cohesive polydensified matrix hyaluronic acid (CPM-HA) fillers. Developed by a panel of 5 global experts, 8 core injection techniques were established to guide procedures, including supporting the oral commissures, enhancing the vermillion border, increasing lateral lip show, increasing vertical height and eversion, improving lip curvature, enhancing lateral structure, and defining the Cupid's bow. The approach outlines a 5-step process: patient interview, documentation, anatomical assessment, lip structure assessment, and treatment, promoting results that are tailored to the patient's unique aesthetic goals and anatomy. Two examples of the application of these core principles are highlighted through the Beautification and Restoration pathways, chosen based on patient-specific needs. Beautification enhances existing lip features, whereas Restoration rebuilds structure lost to aging. Three case studies illustrate how these core principles and techniques are applied in practice, demonstrating how individual patient requirements guide treatment. Case 1 involves a 45-year-old patient seeking subtle lip enhancement. Case 2 outlines the treatment of a 39-year-old patient aimed at restoring lip proportions. Case 3 highlights the treatment for a 57-year-old patient requiring structural support. This methodology provides a flexible, structured framework that adapts to individual patient needs, promoting safe, effective, and consistent outcomes. <b>Level of Evidence</b>: 5 (Therapeutic).
