The goal of this clinical trial is to assess whether a single RF-CWC (radiofrequency - continous water cooling) session can produce significant improvements in jawline contour and facial volume in women aged 38-50 years over 8 weeks. The main questions it aims to answer are:
1. Can one session of RF-CWC elevate the jawline after 8 weeks?
2. Can one session of RF-CWC contour the lower face after 8 weeks? Researchers will compare the jawline lifting effect and mandibular volume at 2, 4, and 8 weeks to baseline values.
