Objectives: Support plastic surgeons in understanding the unique properties of collagen as an injectable material and in mastering periorbital injection techniques. Introduction: In this era where injectable materials are primarily used for volumetric filling, we should educate more doctors that collagen is an injection material focused on nourishment and regeneration. If traditional filler injection techniques are used for collagen, its high cohesion may lead to the formation of clumps. Therefore, we hope that doctors gain a new understanding of collagen, they can quickly adapt their injection practices to perfectly address periorbital aging issues. Materials / method: Materials: Medical Collagen Implant Method: Collagen injection in deep tissues primarily involves anchoring for lifting. In shallower layers like the orbicularis oculi muscle, tightening is mainly achieved through tiled spreading.
