Treatment of periorbital aging with negative pressure fractional microneedle radiofrequency: A self-controlled clinical trial. J Cosmet Dermatol 2023. [PMID: 38013586 DOI: 10.1111/jocd.16091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 10/28/2023] [Accepted: 11/07/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND Several treatment modalities are used for the treatment of periorbital rejuvenation with variable results. Recent studies showed that fractional radiofrequency may be an effective treatment modality for periorbital aging. This study aims to determine the efficacy and safety of negative pressure fractional microneedle radiofrequency (NPFMR) as a treatment for periorbital aging. METHODS Twenty-five patients with periorbital aging were involved in this study. They were treated two times with an interval of 1 month. The patients were evaluated before treatment and 1, 3, and 6 months after the final treatment. RESULTS The research findings suggest that periorbital wrinkles of the patients were significantly improved by VISIA system (p < 0.05). Physiological indicators detected by MPA10 system showed that compared with before treatment, the hydration increased (p < 0.05) and trans epidermal water loss (TEWL) decreased (p < 0.05) at 3 and 6 months after treatment. The glossiness increased at 1 month after treatment compared to pre-treatment (p < 0.05) and returned to the baseline level at 3 and 6 months after treatment. There was no significant change in melanin content (p > 0.05). Periorbital dermal thickness of the patients significantly increased at 1, 3, and 6 months after treatment according to skin ultrasound (p < 0.05). A periorbital skin biopsy revealed that the collagen fibers in the dermis were significantly thicker and more orderly after treatment, and the expression of type I collagen fibers and elastic fibers was increased compared with that before treatment. One patient developed post-inflammatory hyperpigmentation (PIH) at 1 month after the first treatment, which improved after active treatment. No other adverse reactions were observed. CONCLUSIONS NPMFR could be an effective and safe treatment modality for the treatment of periorbital aging.

Clin Ophthalmol 2023; 17:3089-3102. [PMID: 37881780 PMCID: PMC10595163 DOI: 10.2147/opth.s426564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Accepted: 09/27/2023] [Indexed: 10/27/2023] Open
Abstract
Purpose To evaluate the efficacy of multi-frequency RF and IPL + MGX combination for treatment of Meibomian Gland Dysfunction (MGD). Patients and Methods Eligible subjects had signs and moderate-to-severe symptoms of DED (Dry Eye Disease) due to MGD. Subjects underwent 4 treatments at 2-week intervals. Each treatment consisted of intense pulsed light (IPL) followed by radiofrequency (RF) on the periocular skin, followed by meibomian gland expression (MGX). The main outcome measure was the quality of meibum in 15 meibomian glands along the lower eyelid, using the modified Meibomian Gland Score (mMGS). The main hypothesis was a reduction of mMGS between the baseline (BL) and the follow-up (FU). Other outcome measures, such as symptoms measured with the OSDI (Ocular Surface Disease Index) questionnaire, meibography, non-invasive tear break-up time (NIBUT), and matrix metallopeptidase 9 (MMP-9) levels in tear samples were evaluated as well. Results 31 subjects completed the FU. Between BL and FU, mMGS decreased from 30.4 (8.5) to 9.3 (9.5) (-69.3%, 95% CI: -55.6% to -82.9%, p<0.0001); OSDI decreased from 63.6 (17.2) to 25.0 (20.6) (-60.7%, 95% CI: -47.8% to -73.5%, p<0.0001); NIBUT did not change (p=0.92). An adjusted model with a historical control was constructed to allow the comparison of these subjects with those treated similarly with IPL+MGX (but without RF) in a different study. This analysis identified that the change in mMGS was larger when RF was included (-20.9 vs -18.3, adjusted p-value (p_adjusted) <0.05). The difference in OSDI change was not significant (-38.1 vs -25.5, p_adjusted = 0.196). Conclusion Combination of multi-frequency RF and IPL+MGX improves signs and symptoms of MGD. In comparison to a historical control, improvements were generally larger. A randomized controlled study comparing the combination of RF and IPL+MGX with IPL+MGX alone is required to further elaborate the relative contribution of RF.

Abstract
The word "elective" refers to medications and procedures undertaken by choice or with a lower grade of prioritization. Patients usually use elective medications or undergo elective procedures to treat pathologic conditions or for cosmetic enhancement, impacting their lifestyle positively and, thus, improving their quality of life. However, those interventions can affect the homeostasis of the tear film and ocular surface. Consequently, they generate signs and symptoms that could impair the patient's quality of life. This report describes the impact of elective topical and systemic medications and procedures on the ocular surface and the underlying mechanisms. Moreover, elective procedures performed for ocular diseases, cosmetic enhancement, and non-ophthalmic interventions, such as radiotherapy and bariatric surgery, are discussed. The report also evaluates significant anatomical and biological consequences of non-urgent interventions to the ocular surface, such as neuropathic and neurotrophic keratopathies. Besides that, it provides an overview of the prophylaxis and management of pathological conditions resulting from the studied interventions and suggests areas for future research. The report also contains a systematic review investigating the quality of life among people who have undergone small incision lenticule extraction (SMILE). Overall, SMILE refractive surgery seems to cause more vision disturbances than LASIK in the first month post-surgery, but less dry eye symptoms in long-term follow up.

Abstract
Aging of the face is a continuous and dynamic process that occurs due to changes in layers including skin, muscle, fat, and bone. There is an increasing patient preference toward nonsurgical techniques and procedures that require minimal downtime in all aspects of cosmetic surgery. The mainstay of treatment involves the administration of injectable fillers for temple volumization, eyebrow reshaping and forehead contouring, and neuromodulation to reduce the appearance of dynamic rhytids. Surgical and nonsurgical procedures can be used in combination in order to maximize periorbital rejuvenation. This article focuses on nonsurgical rejuvenation of the brow and periorbital complex.

Abstract
This study aimed to evaluate the safety and efficacy of a low-level radiofrequency thermal treatment in an obstructive MGD rabbit model. Meibomian gland orifices of the central two-thirds of the upper and lower eyelid margins were coagulated twice at 2-week intervals using a 5-MHz high-frequency electrosurgical unit. Sixteen eyes of eight rabbits were treated with one session of radiofrequency thermal treatment (radiofrequency group) and eight eyes of four rabbits were followed up without treatment (control group). Lid margin abnormality and corneal staining scores, histologic examination of the eyelids and meibombian gland, and meibography imaging were evaluated just before and 4 weeks after meibomian gland orifice closure and 4 weeks after radiofrequency thermal treatment. Lid margin abnormality score improved significantly for the upper and lower eyelids after radiofrequency thermal treatment (P < 0.001 for both eyelids). Corneal staining score remained unchanged in the radiofrequency group; however, the control group saw an increase at final follow-up. There was a significant improvement to almost baseline levels in the mean area of secretory acini in the radiofrequency group (P = 0.004). Additionally, meibography indicated an improvement in meibomian gland loss rate in the radiofrequency group. Low-level radiofrequency thermal treatment heating the inner and outer eyelid surfaces is safe and effective to treat obstructive MGD in a rabbit animal model of MGD.

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.

Abstract
BACKGROUND Radiofrequency is a commonly used method to non-invasively tighten the skin that can be safely applied to any skin type. AIMS The aim of our study was to evaluate the safety and efficacy of the focused radiofrequency and ultrasound hybrid device for face and neck rejuvenation, in terms of improvement of facial wrinkles and jaw sagging. METHODS A total of 158 patients had undergone four weekly sessions of focused radiofrequency and ultrasound to face and neck area. Photodocumentation was obtained before first visit and two weeks after last visit. An independent, blinded dermatologist evaluated the severity of wrinkles and sagging of seven different anatomical regions on a validated scale of 0-4 (0: no lines/sagging, 1: mild, 2: moderate, 3: severe, 4: very severe) before and after the procedure. Patients rated their satisfaction with the result of the treatment on a scale of 1-5 (1: dissatisfied, 2: poorly satisfied 3: satisfied, 4: very satisfied, 5: perfectly satisfied). RESULTS For seven anatomical regions, statistically significant reduction was observed in mean wrinkle/sagging scores (p = < 0.001). Patients were satisfied with the effects of the procedure, with a mean satisfaction score of 4.61 ± 0.55. CONCLUSIONS Our findings demonstrate that combined focused radiofrequency and ultrasound is an effective and safe method for the rejuvenation of different sub-areas of the face and neck with high patient satisfaction scores.

Abstract
Background Over the past 10 years, monopolar radiofrequency (MRF) technology has been widely used by dermatologists as a valuable modality to effectively tighten and rejuvenate photoaged skin. It also has the benefit of a short recovery time. Objective Using an objective parameter, this study aimed to assess the efficacy and safety of MRF, which is the basic modality of radiofrequency technologies, for treatment of periorbital wrinkles in Korean patients. Methods We enrolled 70 middle-aged female patients with periorbital wrinkles for this study. Each patient underwent triple sessions of MRF treatment in the periorbital region, separated by 2-week intervals. Clinical photographs were obtained, and the areas of wrinkles were measured using a Robo Skin Analyzer CS50 (Inforward Inc., Japan) at baseline and 4 weeks after the final treatment session. Results Significant reduction in the mean area of periorbital wrinkles was detected at 1-month follow-up (80.64±28.96 mm2) compared to baseline (95.08±31.93 mm2). The improvement ratio of the wrinkle area was 15.19%. Pain during procedure seemed to be tolerable without any local anesthesia for all patients. Transient mild erythema was the only side effect reported during the study. Conclusion In conclusion, MRF could still be an attractive modality for Korean patients with periorbital wrinkles if the treatment is conducted repeatedly with sufficient energy and proper intervals.

Abstract
The nonablative radiofrequency is a procedure commonly used for the treatment of skin
laxity from an increase in tissue temperature. The goal is to induce thermal damage
to thus stimulate neocollagenesis in deep layers of the skin and subcutaneous tissue.
However, many of these devices haven't been tested and their parameters are still not
accepted by the scientific community. Because of this, it is necessary to review the
literature regarding the physiological effects and parameters for application of
radiofrequency and methodological quality and level of evidence of studies. A
literature search was performed in MEDLINE, PEDro, SciELO, PubMed, LILACS and CAPES
and experimental studies in humans, which used radiofrequency devices as treatment
for facial or body laxity, were selected. The results showed that the main
physiological effect is to stimulate collagen synthesis. There was no homogeneity
between studies in relation to most of the parameters used and the methodological
quality of studies and level of evidence for using radiofrequency are low. This fact
complicates the determination of effective parameters for clinical use of this device
in the treatment of skin laxity. The analyzed studies suggest that radiofrequency is
effective, however the physiological mechanisms and the required parameters are not
clear in the literature.

Abstract
Electrosurgical currents can be delivered to tissue in monopolar or bipolar and monoterminal or biterminal modes, with the primary difference between these modes being their safety profiles. A monopolar electrosurgical circuit includes an active electrode and a dispersive (return) electrode, while there are 2 active electrodes in bipolar mode. In monoterminal mode, there is an active electrode, but there is no dispersive electrode connected to the patient's body and instead the earth acts as the return electrode. Biterminal mode uses a dispersive electrode connected to the patient's body, has a higher maximum power, and can be safer than monoterminal mode in certain situations. Electrosurgical units have different technologies for controlling the output power and for providing safety. A thorough understanding of these technologies helps with a better selection of the appropriate surgical generator and modes.
