This PubMed-listed study models and experimentally validates how subcutaneous fat thickness affects temperature distribution during monopolar radiofrequency (RF) treatment used for skin tightening and tissue repair. Using finite element analysis (COMSOL) and in vitro pork tissue experiments, the authors report that thicker fat layers reduce achieved intratissue temperatures under the same RF settings. The paper concludes that RF energy parameters may need adjustment based on adipose thickness to reach desired effects while staying within stated epidermal safety limits.
