Subdermal monopolar radiofrequency (RF) redefines jawline by delivering controlled thermal energy that induced soft tissue contraction. However, the type of candidates best suited for this treatment has not been determined. A retrospective analysis of the treatment results and satisfaction, at 6 weeks and 3 months, in 15 female patients, aged 34 to 77 years, with mild to moderate skin laxity (Submental Skin Laxity Grading [SMSLG], 1-3) and submental fat (SMF) (Clinician rating-SMF-Rating Scale [CR-SMF-RS], 1-3), and a Subject Self Rating Scale (SSRS) ≤2. They received ThermiRF to either jowl and neck or neck only, in a single clinic, between the period of October 2017 to July 2018. The probe treatment temperature was set and maintained between 52°C to 65°C whereas the epidermal temperature was targeted around 42°C to 43°C. All patients with SMSLG 2 to 3, reported at least 1 grade SMSLG response with a mean change of 1.23 of CR-SMF-RS and mean change of 3.08 of SSRS. None of the patients experienced a burn or erythema following treatment. Transient swelling, nodule and mild numbness following ThermiRF procedure has been reported but all resolved completely with time. All reported GAIS ≥3 and 46.7% reported a Global Aesthetic Improvement Scale (GAIS) score of 5, i.e. optimal results by 3 months. Therefore, according to treatment results those with good to at least moderate skin laxity (SMSLG, 2-3), mild to moderate SMF (CR-SMF, 1-3) and absent of platysmal pathology reported at least a one-grade improvement on SMSLG and CR-SMF-RS within 3 months of ThermiRF treatment. Level of Evidence: IV
