Tawfic SO, Hassan AS, El-Zahraa Sh Aly F, Elbendary A, Shaker OG, AlOrbani AM. Fractional microneedle radiofrequency versus fractional carbon dioxide laser in the treatment of postburn hypertrophic scars. Lasers Surg Med 2022; 54:1089-1098. [PMID: 35900305 DOI: 10.1002/lsm.23589] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 07/01/2022] [Accepted: 07/15/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND AND OBJECTIVE New and improved treatment modalities, including lasers and energy-based devices, are promising treatment options for hypertrophic scars. This study aimed to assess the efficacy and safety of fractional microneedle radiofrequency (FMR) compared with fractional carbon dioxide (CO2 ) laser in the treatment of postburn hypertrophic scars. PATIENTS AND METHODS Twenty patients with hypertrophic scars were enrolled in the study. Two areas in each patient were randomly assigned to fractional CO2 laser or FMR. Four sessions, 6-8 weeks apart were performed. The Patient and Observer Scar Assessment Scale (POSAS) was used for clinical evaluation, H & E and orcein-stained samples were examined for histopathological assessment, and tissue transforming growth factor beta 1 (TGFβ1 ) levels were measured for biochemical evaluation. RESULTS Both fractional CO2 and FMR-treated areas showed significant improvement in all parameters 1 month after treatment. Fractional CO2-treated areas showed a higher degree of improvement compared with FMR in OSAS (p = 0.025), elastin grading (p = 0.004), and TGFβ1 levels (p = 0.000). Patients reported less downtime and showed less postinflammatory hyperpigmentation with FMR compared with fractional CO2, but this did not reach statistical significance (p = 0.327, p = 0.231; respectively). CONCLUSION Our results demonstrate the value of FMR as an effective alternative to fractional CO2 in the treatment of hypertrophic scars, with a potentially favorable safety profile.

Abstract
Increasingly, there is an attempt to minimize expression lines through esthetic procedures, and radiofrequency (RF) is one of the therapeutic modalities. This article aims to systematically review the literature on the different types of RF treatment in clinical trials and in variables related to the aging process. This systematic review included 21 articles that treated 354 people with different physical characteristics. The most used RF was the fractional followed by the non-ablative RF. There was a large discrepancy in relation to the types and parameters. A parameter that did not show so much divergence was the temperature, which was between 38°C and 44°C. The main temporary adverse reactions reported by the authors were as follows: discomfort, pain, erythema, hyperpigmentation, crusting, swelling, edema, and purple and acneic appearance of the skin. Finally, our study concluded that non-ablative and ablative RF was reported to rejuvenate and improve the features of skin in all skin types.

Abstract
BACKGROUND Radiofrequency technology has emerged as a treatment for aesthetic rejuvenation. OBJECTIVE To examine radiofrequency for facial and neck rejuvenation, clinical studies were assessed on effectiveness and safety of radiofrequency for acne, acne scars, and facial aging by subjective and objective measures. METHODS A systematic literature review was performed. Eligibility criteria included articles in English, primary literature, clinical or ex vivo studies, use of radiofrequency, and face or neck treatment. Ablative techniques, home-use devices, combined modalities, and studies unrelated to rejuvenation were excluded. All studies were appraised for quality and biases. RESULTS We identified 121 articles. Radiofrequency effectively treated acne by reducing sebum levels and lesion count and improving acne scars. Radiofrequency demonstrated a volumetric reduction in facial fat, and improved skin laxity, elasticity, and global skin aesthetic. Patient satisfaction was higher for those desiring modest rejuvenation. There were histological changes consistent with repair response, neocollagenesis, and neoelastinogenesis. Radiofrequency was safe apart from one patient who developed a neck fistula. CONCLUSION Most studies demonstrated radiofrequency treatment of acne, scars, or facial rhytids had positive subjective improvement ratings. Objective studies demonstrated reduction of acne, decreased scarring, lifting effect, improvement in elasticity and collagen, volumetric fat changes, and wrinkle reduction.

Subject satisfaction following treatment with nanofractional radiofrequency for the treatment and reduction of acne scarring and rhytids: A prospective study. J Cosmet Dermatol 2021; 20:3475-3481.

Abstract
Background Skin‐related changes, such as fine lines, wrinkles, and acne scarring, are a source of distress to both men and women. Nanofractional radiofrequency delivers thermal energy to skin layers leading to dermal remodeling that can address skin conditions related to aging. The objective of this study was to evaluate the subject satisfaction of nanofractional radiofrequency for the treatment of facial wrinkles and acne scarring in both lighter and darker skin tones. Materials and methods 30 subjects (skin types II‐VI) were enrolled in this prospective, evaluator‐blind study. The average age of subjects was 51.9 ± 13.5 years. Subjects received three treatments at 3‐ to 5‐week intervals on both sides of the face using the 80‐ or the 160‐pin tip disposables. Follow‐up visits were conducted at 6‐ and 12 weeks after the last treatment. Subject satisfaction was evaluated using a self‐assessment of a reduction of wrinkles or acne scars, and subject satisfaction questionnaire. Pain, tolerability, and safety were monitored throughout. Results Subjects treated for acne or wrinkles were satisfied with their treatment at both the 6‐week and 12‐week follow‐up visit (mean score 3.0; range 0 = very unsatisfied to 4 = very satisfied). The treatments were well tolerated at all treatment sessions, averaging a score of 3.5 on the tolerability scale (0 = very intolerable to 4 = very tolerable) with treatment‐associated pain reported to be mild (3.2 out of 10). There were no adverse events or unanticipated side effects. Conclusions This clinical study demonstrates subjects are satisfied with nanofractional radiofrequency treatments for improvement of their wrinkles and acne scars.

J Cosmet Dermatol 2020; 19:1636-1641.

Abstract
BACKGROUND Multiple treatment modalities have been developed to treat atrophic acne scars with varying degrees of success. Post-inflammatory hyperpigmentation (PIH) after acne scar treatments remain a major concern in Asian patients. Fractional radiofrequency (FRF) has been used in many dermatological skin conditions including acne scars. AIMS To determine the efficacy and safety of FRF nanoneedle system in the treatment of acne scars in Asians. METHODS This is a prospective, evaluator-blinded study with 25 subjects diagnosed with moderate to severe acne scarring. All subjects received 3 monthly treatments of the FRF nanoneedle system on both cheeks. Primary outcome was the clinical improvement of acne scars graded by 2 blinded dermatologists at baseline, 1-, 3-, and 6-month follow-ups. Objective scar volume analysis was done using ultraviolet A (UVA) light video camera. Subjects' self-assessment, pain score, and adverse events were also recorded. RESULTS Twenty-three out of 25 subjects completed the study and attended all follow-up. Clinical improvement of acne scars was observed as early as 1-month follow-up. Objective evaluation of acne scar volume decreased significantly on all follow-up compared to baseline (P < .005). Majority of the subjects (48%) reported marked improvement in their acne scars. Adverse events such as pain, erythema, burning sensation, edema, scab formation, and PIH were mild and temporary. CONCLUSIONS FRF nanoneedle system is a safe and effective treatment for acne scars in Asians. However, despite the significant changes in the scar volume, caution should be used to avoid excessive coagulation resulting in PIH.
