Two agents dominate injectable lipolytic practice: deoxycholic acid (DCA) as a single agent, and phosphatidylcholine combined with deoxycholic acid (PC/DCA) as a combination formulation. Both destroy subcutaneous fat cells, both produce the inflammatory clearance response that delivers the result, and both are available as CE-marked Korean formulations at Celmade. But they are not identical — and practitioners who understand the specific differences between them are better positioned to choose the right product for each clinical situation.
