Objectives: To present the Swedish Lip™ technique, a shape-driven, cannula-based method that prioritizes anatomical analysis, selective volumization of concave areas, and controlled projection for natural, flat-profile lip outcomes. Introduction: Traditional lip augmentation techniques often focus on uniform volumization or border enhancement. However, equal distribution of filler across convex and concave areas may preserve existing projection patterns rather than refine them, increasing the risk of unnatural borders and over-projection. Materials / method: The technique is structured in three stages: (1) consultation and lip-type analysis, (2) treatment in front of the orbicularis oris muscle, and (3) selective treatment behind the muscle when greater structural change is required. Emphasis is placed on identifying convex and concave regions of the vermilion, surface, and cutaneous lip. Filler is placed exclusively in concave areas, typically in the subdermal plane using a 27G 40 mm flexible cannula and microdroplet technique. The vermilion border is generally avoided except at the Cupid’s bow. When increased projection or eversion is desired, p Results: Clinical cases demonstrate improved lip flatness in profile, smoother transitions between lip subunits, reduced migration, and minimized border projection. The technique allows for greater control, reduced bruising, and prolonged working time due to cannula-based placement. Conclusion: The Swedish Lip™ represents a structural shift from volumetric augmentation to morphological refinement. By respecting lip compartment anatomy and selectively targeting concave regions, it enables natural, balanced, and long-term stable lip outcomes while reducing the risk of artificial projection.
