Bottom Line: No serious adverse events were observed.Mild adverse events reported were slight erythema, scale, and crust.The 27.12 MHz RF treatment of benign vascular and nonvascular lesions appears safe and effective after 3 weeks of follow-up.

ABSTRACT
As surgical and/or ablative modalities, radiofrequency (RF) has been known to produce good clinical outcomes in dermatology. Recently, 27.12 MHz RF has been introduced and has several advantages over conventional 4 or 6 MHz in terms of the precise ablation and lesser pain perception. We aimed to evaluate the clinical efficacy and safety of 27.12 MHz RF for the treatment of benign cutaneous lesions. Twenty female patient subjects were enrolled. Digital photography and a USB microscope camera were used to monitor the clinical results before one session of treatment with 27.12 MHz RF and after 1 and 3 weeks. Treated lesions included telangiectasias, cherry and spider angiomas, skin tags, seborrheic keratoses, lentigo, milium, dilated pore, acne, piercing hole, and one case of neurofibroma. For vascular lesions, clinical results were excellent for 33.3%, good for 44.4%, moderate for 11.1%, and poor for 11.1%. For nonvascular lesions (epidermal lesions and other benign cutaneous lesions), clinical results were excellent for 48.3%, good for 45.2%, moderate for 3.2%, and poor for 3.2%. No serious adverse events were observed. Mild adverse events reported were slight erythema, scale, and crust. The 27.12 MHz RF treatment of benign vascular and nonvascular lesions appears safe and effective after 3 weeks of follow-up.

Mentions: Representative photographs of positive clinical treatment outcomes for different skin lesion types treated with RF are presented in Figure 1. The clinical treatment outcomes of vascular lesions indicated that 12 cases (33.3%) showed excellent results; 16 cases (44.4%) showed good results; 4 cases (11.1%) showed moderate results; and 4 cases (11.1%) showed poor results (Table 2). Lesions situated on the face showed good response to the treatment. Two of the subjects showing moderate improvement had a medical history of photodamaged skin and rosacea, respectively. The anatomic sites of cases which showed poor results were nasal ala and upper eyelid, which are generally prone to pain. Besides, nasal ala is generally difficult to approach.
