Radiofrequency microneedling (RFM) has recently become a popular choice for the treatment of various dermatologic conditions and rejuvenation. Many studies have sought to evaluate the efficacy of RFM. However, its role in the management of these conditions remains unclear. A comprehensive literature search including randomized controlled trials, cohort studies, and case series evaluating the efficacy of RFM in various skin conditions was performed. In this review, we discuss the history and mechanism of RFM, describe various device features, and discuss the use of RFM in various skin conditions and rejuvenation.

Given the relevance of laser application, the objective of this study was to carry out a systematic review to verify the therapeutic effects of laser application on psoriasis plaques. The databases used were PubMED, Scopus, Embase, Cochrane, Web of Science, and in the gray literature: Google Scholar, Open Grey and LIVIVO. A total of 1,227 records were found, after removal of duplicates 851 studies remained for Phase 1 (reading titles and abstracts) and 31 for Phase 2 (reading the full studies) and finally 9 studies remained for this review, 7 randomized and 2 non-randomized. The risk of bias analysis had two studies with moderate risk and seven with high risk. The present study presented evidence that laser application has positive effects such as reduction of psoriasis plaques. However, due to the high risk of bias, there is a need for further studies.

Objective: to report a possibly novel complication of laser hair removal.

Case report: a white-skinned 18-year-old patient discovered an umbilical, brown, and raised lesion while shaving before his second diode laser hair removal session. He sought consultation before his fourth laser session since the lesion further thickened and darkened. Dermoscopy showed no pigmented network, but a few comedo-like openings within an erythematous-light brown scaly and fissured papule, "moth-eaten" borders, and a central crust due to manipulation, suggesting the diagnosis of seborrheic keratosis. We noted that the laser fluence was increased on the umbilical region where hair seemed resistant to treatment. The patient denied a recent history of local sun tanning, sunburns, inflammation, drainage, or manipulation. The lesion cleared, with no short-term relapse, after one session of cryotherapy.

Conclusion: the development of a seborrheic keratosis-like lesion on a densely haired non-sun-exposed umbilicus of a young patient, following pre-laser shaving and high-fluence hair removal diode laser sessions, could have implicated triggering irritation and/or keratinocyte stimulation by red light-engendered reactive oxygen species (ROS) in the skin with silent epidermal mosaicism.

Port-wine stains (PWS) are frequently refractory to laser treatments. The aim of this study is to evaluate the role of treatment interval time. From 1990, 216 patients underwent Pulsed Dye Laser sessions. The laser sessions were scheduled at a minimum interval of 4 weeks to a maximum of 48 weeks. Clinical outcomes were assessed 8 weeks after the last laser session. Better results were obtained with 8 weeks interval time between therapy session, and high efficacies were also found for intervals of 4, 6 and 10 weeks. For greater interval instead, the effectiveness is significantly lower.

Background: Striae gravidarum (SG) is a common pregnancy-related dermatologic problem, for which finding an effective treatment remains a challenge.

Aim: To evaluate the safety and efficacy of 1540 nm non-ablative fractional laser (Star lux 500) in the treatment of SG in Iranian women and peruse the relationship between clinical improvement rate and patient characteristics as well as clinical features of striae.

Method: A prospective before-after study was conducted on 50 patients with SG who received three monthly sessions of 1540 nm non-ablative fractional laser and were followed for 2 months after the last treatment session. Clinical changes were measured using both provider-rated outcome through before/after pictures represented by final clinical score (from 0 to 5) and patient-reported outcome (patient global assessment or PGA).

Results: Over the course of the study both final clinical score and PGA increased significantly from week 4 to week 20 (P value: <0.001 and 0.048, respectively). Only modest adverse effects including erythema, edema and hyperpigmentation were noted.

Conclusion: In conclusion, patients with SG of different type (rubra/alba) or maturity may somehow benefit from treatment with NAFL experiencing minimal transient side effects.Therefore, NAFL may be considered a safe and partially effective treatment option for stretch mark of patients with SG.

Background: Cellulite of the upper lateral and posterior thighs and lower buttocks represents a common unwanted condition.

Objectives: The author sought to comparea LLLT-LED bed therapy and a novel topical anti-cellulite gel on one thigh/buttock cellulite vs light therapy for cellulite to the opposite side.

Methods: Eight healthy female subjects were randomly treated with a LLLT-LED bed twice weekly for 20 minutes in prone/supine positions with twice daily application of a novel anti-cellulite gel to one randomized thigh/buttock.

Results: At the end of the 3-month trial, skin elasticity increased after combined therapy on one thigh but decreased with only LLLT-LED bed treatments on the opposite thigh. Thighs treated with active gel and LLLT-LED bed, were downgraded to a lower cellulite grade, while monotherapy did not demonstrate any change from their baseline cellulite grading. Changes in thigh circumference did not correlate with either treatments regimens.Subject and investigator questionnaire evaluations at month-3 were assessed as "satisfactory" results. There were no adverse reactions to treatments.

Conclusions: The use of LLLT-LED bed therapy and an anti-cellulite gel demonstrated an efficient alternative in the treatment of cellulite-involved thighs/buttocks over similarly affected thighs/buttocks that were treated only with LLLT-LED bed therapy.

The lack of uniform and objective techniques to evaluate treatment efficacy in photo-epilation studies leads to contradictory results. Thus, there is an urgent need to explore commonly accepted assessment tools. One of the most common methods uses hair counts via digital photography. However, macrophotography may not be able to depict the vellus-like hair induced by photo-epilation. On the other hand, handheld dermatoscopy is practical, affordable and offers high-quality magnification. Hair counts from a handheld dermatoscope and a digital camera were compared in 73 women who underwent 6 sessions with the Alexandrite 755 nm laser. Significantly more hairs were counted using the dermatoscope than using the digital camera (76.9 ± 41.3 vs. 58.6 ± 31.4, p < .005), independently of hair thickness and hair density. The difference in hair counts between the two instruments was inversely related to hair thickness and directly related to hair density. The handheld dermatoscope may be a more effective tool than the widely used digital camera in evaluating the response to laser hair removal treatment.

The goal was to determine ways to optimize diagnostic and therapeutic measures for various types of melasma in the outpatient setting of the dermatovenerological ambulatory clinic. The study involved 112 women with a confirmed diagnosis of facial melasma whose disease lasted for at least 2 years. The severity of patient pigmentation was evaluated using the Melasma Area Severity Index and the Melasma Severity Scale. There was a significant increase in melanin levels across all melasma types, an increase in erythema in the dermal type, and an increase in sebum production in the epidermal type.
