Facial erythema is a representative symptom of rosacea patients that greatly impairs quality of life. Recently, the therapeutic effects of intradermal injection of botulinum toxin type-A on erythema have been investigated. Fractional microneedling radiofrequency has been reported to be effective in dermal remodeling and anti-inflammation. To obtain enhanced therapeutic effects with a less painful and easier approach, a treatment regimen using transdermal botulinum toxin delivery with fractional microneedling radiofrequency was developed. We aimed at investigating the efficacy and safety of transdermal botulinum toxin delivery with fractional microneedling radiofrequency in treating the erythema of rosacea. This was a retrospective review of 20 patients with facial erythema associated with rosacea. All patients underwent two sessions of treatment at 4-week intervals. Standardized photographs were taken, and the clinicians' erythema assessment (CEA), erythema index (EI) measured through a spectrophotometer, investigator's global assessment (IGA), and subjective satisfaction and side effects were evaluated at the baseline and 4, 8, and 12 weeks after the baseline. Compared to the baseline, CEA levels significantly decreased after 8 weeks (P = 0.018) and 12 weeks (P = 0.005). As an objective measure, EI was observed to decrease significantly at 4 weeks (P = 0.04) and 8 weeks after the baseline (P = 0.005) compared with the baseline. Ninety-five percent of patients were either very satisfied or satisfied with the treatment. None of the patients experienced remarkable side effects. A novel treatment regimen involving transdermal botulinum toxin delivery and fractional microneedling radiofrequency may be an effective and safe option for reducing the facial erythema of rosacea.

The aim of this questionnaire‐based study was to measure the level of appreciation, practice patterns, and side effects of monopolar radiofrequency treatment among Korean dermatologists practicing the most updated monopolar radiofrequency device (Thermage FLX, Thermage Inc., Hayward, California). According to a total of 52 surveys analyzed, this latest device (Thermage FLX) was considered more effective (57.4%), faster with reduced treatment time (66.0%), and more painful (25.5%) compared with Thermage CPT. Asians in their 40s were considered to benefit most and skin thickness continued to be the most important determinant in terms of responsiveness to Thermage FLX. The interval between treatments was mainly 1 year (51.9%) with the 600 REP 4 cm2 new total tip being preferred by 86.5% of Thermage FLX users. The treatment energy and the complication rate of Thermage was lower than what we reported in 2017 and 2011 which is likely due to the optimized energy delivery of Thermage FLX and the subsequent gentle treatment. We hope our updated data enable dermatologists to better utilize monopolar radiofrequency in their practice. [ABSTRACT FROM AUTHOR]

Despite multiple individual studies proving efficacy of grid fractional monopolar radiofrequency (Grid RF) and near‐infrared irradiation 1064‐nm long‐pulsed neodymium:YAG laser (Laser Genesis), there is a lack of controlled comparative trials between these devices. This study aims to compare the efficacy and safety of Grid RF versus Laser Genesis in the treatment of periorbital rhytides. This is a randomized, single‐blind, split‐face, prospective study. Eight patients with moderate to severe periorbital rhytides were treated with either Grid RF or Laser Genesis on each side of the face. Photographic and live assessment with the Lemperle Wrinkle Assessment grading scale was compared after 2 months. Difference in scores between Grid RF vs Laser genesis groups after 2 months was not statistically significant (P = 0.244). Each group showed statistically significant improvement months post‐procedure (P <.05). Immediate adverse effects and satisfaction scale were similar for both groups (P >.05). At 2 months follow‐up, no adverse effects were seen. Grid monopolar radiofrequency (Grid RF) vs near‐infrared radiation 1064 nm long‐pulsed Nd‐YAG laser (Laser Genesis) were equally efficacious, safe, and well‐tolerated among patients in the treatment of periorbital wrinkles (P >.05).

Recently great attention has been paid to the rejuvenation of the face, neck, and décolleté of women with advanced radial fractional radiofrequency. We aimed to clinically evaluate the results obtained with this treatment method. We treated 10 women aged 42 to 62, suffering from skin aging. After carrying out the hydration and sebometry skin tests in each patient, collecting the medical history and taking photographs of the face and décolleté in the standard projections, a questionnaire was submitted to each patient. Finally, we have submitted the patients to one session of application of radiofrequency energy, by an Italian device named "Thuzzle" (GMV, Rome, Italy). The obtained results show a high effectiveness in improving the texture and tone of skin, decreasing micro wrinkles and spot reduction. Advanced radial fractional radiofrequency treatment method shows promising results. Further studies are required to confirm the findings. [ABSTRACT FROM AUTHOR]
