“…Prior studies with the original 1-cm tips have shown good results in skin tightening over the forehead, cheeks, periorbital area, jowls, and neck with treatment energies ranging from 58 to 144 J/cm 2 [3][4][5][6]. In the first multicenter trial to evaluate non-ablative, monopolar radiofrequency for skin tightening, Fitzpatrick et al [3] found a baseline to 6-month improvement in 83% of subjects, treating at energies of 58-140 J/cm 2 and an average 68 repetitions (REPS) per treatment.…”
