Efficacy of monopolar radiofrequency in middle and lower face laxity

Aim: In recent years, radiofrequency (RF) systems have become one of the most commonly used rejuvenation methods, especially in the skin of the mid-lower face. In this study, the efficacy of monopolar RF energy in mid-lower face skin sagging was evaluated. Material and Methods: A total of 42 patients between the ages of 34 and 67 were included in this study. All patients underwent monopolar RF and were followed for 6 months. The monopolar RF energy level was determined based on the maximum level that each patient could tolerate. Patients were photographed with a digital camera before and 6 months after the procedure. The sagging grade of the mid-lower face before and after treatment was determined using the Merz skin laxity scale (MSLS). According to the MSLS, the level of laxity was divided into 5 groups: none, mild, moderate, severe, and very severe. The patient satisfaction levels were grouped into the following categories: not satisfied, minimally, well, and perfectly satisfied. Patients were monitored for side effects. Results: After the RF treatment, the mean MSLS score decreased from 2.60±0.80 to 1.86±0.87. The decrease in skin laxity after treatment was statistically significant (p=0.0001173). Patient satisfaction was correlated with treatment response (p=3.7x10-7). Erythema and edema were observed in all 42 patients; two patients complained of fat tissue reduction. Conclusion: Monopolar RF is an effective method for treating mid-lower face skin laxity. However, RF energy applied at high energy parameters may lead to thinning in the subcutaneous fat layer.
