Participants underwent a single RF-CWC treatment on Day 0 after eligibility screening and baseline assessments. Treatment was applied using two distinct modes based on anatomical regions. The static mode was administered to the outer facial areas, while the sliding mode was applied to the central facial areas. This approach allowed for region-specific assessment of volumetric changes corresponding to each treatment mode. Follow-up visits were conducted at weeks 2, 4, and 8.

Jawline lifting was evaluated using Morpheus3D® (Morpheus Co., Ltd., Gyeonggi, Republic of Korea), an LED-based 3D facial imaging system. Jawline lifting was measured as the curved distance (mm) from the chin to the earlobe; a decrease in length indicated improvement.

Facial volume was evaluated using Morpheus3D® (Morpheus Co., Ltd., Gyeonggi, Republic of Korea), an LED-based 3D facial imaging system. Facial volume (ml) was assessed for two regions: the midface (between the eyes and the area from philtrum to nose), where an increase indicated volumization, and the lower face (philtrum to chin), where a decrease indicated contouring.
