Background: The "4.3" technique is a hybrid lip augmentation approach that combines the aesthetic benefits of the vertical-lip technique with the fewer entry points of the retrograde linear technique. This method aims to create natural-looking, harmonious, and defined lips using hyaluronic acid (HA)-based fillers, to enhance volume and contour.

Aims: The objective of this study is to evaluate the effectiveness, safety, and reproducibility of the "4.3" technique in achieving natural lip augmentation with minimal filler volume and reduced injections. This technique is applied to improve the shape and volume of the lips while minimizing the risk of complications.

Patients/methods: The technique was applied to male and female patients with standard anatomical features who desired subtle enhancements in lip contour, projection, and volume. The procedure involved four injections in the upper lip and three in the lower lip, using a combination of retrograde linear and vertical techniques. A total of 0.7 mL of HA filler were used for each patient.

Results: The "4.3" technique achieved consistent and aesthetically pleasing results across all patients, with improvements in lip volume, shape, and definition. The reduced number of injections minimized discomfort and risk of vascular complications. The use of Tri-Hyal technology contributed to smooth, plump lips with harmonious proportions.

Conclusions: The "4.3" technique is a standardized, intuitive, and reproducible method suitable for most patients, regardless of sex. It allows for natural-looking lip augmentation using a reduced volume of filler and fewer injections, making it a safe and effective option for enhancing lip aesthetics.

Background: Poly-l-lactic acid (PLLA) injectables have gained increasing attention in aesthetic medicine due to their biocompatibility and long-lasting effects. Although their primary application centers around facial rejuvenation, their potential for off-label use in other body areas has been investigated, demonstrating promising outcomes in terms of both efficacy and safety.

Aim: This study aims to assess the safety and efficacy of a novel 630 mg PLLA-based filler (GANA X), in buttocks treatment.

Methods: Six physicians treated 51 patients for buttock aesthetic treatment across six different medical facilities in Italy. A survey was filled by both physicians and patients regarding treatment safety, efficacy, and change in quality of life.

Results: We reported minor or mild adverse events, self-resolving within the next few days. Both physicians and patients confirmed notable aesthetic improvements following treatment, varying from moderate to significant enhancement. These effects endured throughout follow-up visits spanning up to 24 months. Patient-reported outcomes indicated elevated self-esteem and improved quality of life posttreatment.

Conclusions: The high level of satisfaction reported by both physicians and patients highlights the efficacy and tolerability of GANA X filler for buttocks treatment, encouraging their use and research for off-label body areas.

Objective: To investigate the role of miR-30a-5p on the proliferation and apoptosis of hair follicle stem cells (HFSCs) and whether the Wnt/β-catenin signaling pathway is involved.

Methods: HFSCs derived from the vibrissa of mammary rats were obtained by enzymatic digestion, and subsequently the obtained HFSCs were treated with Lipofectamine 2000 cell transfection and divided into normal cell culture group (control), miR-30a-5p overexpression group (miR-30a-5p mimic), miR-30a-5p empty vector group (miR-NC), miR-30a-5p inhibitor group (in-miR-30a-5p), and in-miR-30a-5p empty vector group (in-miR-NC). After transfection, the cell proliferation and apoptosis rates were examined separately. In addition, the mRNA expression of β-catenin, proliferating cell nuclear antigen (PCNA) and apoptosis-related genes (Bax and Bcl-2) were examined.

Results: The results of cell proliferation ability showed that in-miR-30a-5p group promoted cell proliferation of HFSCs relative to other groups, along with significant upregulation of gene levels of PCNA. Apoptosis analysis indicated that apoptosis rate was reduced in the in-miR-30a-5p group, and the expression of Bax was suppressed, while that of Bcl-2 was promoted. Wnt/β-catenin signaling pathway investigation revealed a significant increase in the levels of β-catenin in HFSCs in the in-miR-30a-5p group.

Conclusion: Downregulation of miR-30a-5p levels inhibited HFSCs apoptosis and simultaneously promoted proliferation, furthermore, the increased expression of β-catenin indirectly confirmed the activation of the Wnt/β-catenin signaling pathway.

Background: Cocoa powder derived from the Theobroma cacao plant is rich in polyphenols, such as catechin and epicatechin. These polyphenols are strong antioxidants when consumed orally; however, their ability to enter the stratum corneum following the topical application has never been demonstrated.

Objective: The objective of this study was to demonstrate the deposition of catechin and epicatechin in the stratum corneum following the topical application of 6% aqueous cocoa powder 1 and 2 h after application.

Methods: Five healthy female subjects aged 25-60 years were enrolled. A 6% aqueous cocoa powder solution was prepared and applied to two randomized designated spots on the left forearm. 2 cc of the solution was applied under a ¼-inch gauze square covered with plastic wrap and held in place with a Coban dressing. The 15 d-squame 7/8-inch circular tape strips were applied to the predetermined area on the forearm 1 h and 2 h after application of the 6% cocoa powder solution. The tape strips were immediately placed in a -80°C freezer for storage until extraction in preparation for LC-MS evaluation for catechin and epicatechin levels.

Results: More catechin and epicatechin were detected at 2 h than 1 h for both compounds, although the difference was not statistically significant. Higher epicatechin levels than catechin levels were detected from the cocoa powder at both time points. This is consistent with published data from food-grade cocoa powder.

Summary: It is detected that 6% aqueous cocoa powder delivers the antioxidants catechin and epicatechin to the stratum corneum 1 h and 2 h after topical application.

Introduction: This prospective study evaluates the efficacy and safety of minimally invasive radiofrequency microneedling (RFMN) for the correction of periorbital wrinkles. This study aimed to address the challenges posed by the periorbital region's unique anatomy and the limitations of existing non-surgical treatments.

Methods: Twenty-four subjects, ranging from 34 to 54 years old with Fitzpatrick skin types II-V, underwent a series of treatments using the Voluderm RF microneedling device. Participants were divided into two groups based on the severity of their wrinkles and treated with customized protocols over four sessions, with a 3-month follow-up to assess outcomes. Efficacy was determined through comparisons of pre-treatment and post-treatment wrinkle severity, using the Lemperle Classification of Facial Wrinkles (LFW) and the Global Aesthetic Improvement Scale, evaluated by both the investigators and the patients. Safety and tolerability were assessed through adverse event reporting and a Visual Analog Scale for treatment discomfort.

Results: The results demonstrated a statistically significant reduction in periorbital wrinkle severity, with an average 49% decrease of LFW score and improvements noted across all skin types in both groups. The aggregated facial LFW score decreased from baseline mean 13.00 ± 4.75 to 6.09 ± 3.90 (p < 0.05). The treatment was well tolerated without anesthetics, with minimal downtime and few adverse events, which were transient and resolved without intervention.

Conclusion: The efficacy of Voluderm RF microneedling in improving periorbital wrinkles of variable severity was demonstrated in patients with diverse skin types. The unique RF-assisted mechanism of the skin penetration granted a high tolerability of the treatments, negligible downtime, and minimum number of adverse events with self-resolution.

Background: Rosacea is a chronic inflammatory skin disease characterized by flushing, erythema, papules, and pustules on the central face. It affects patient appearance and is noted for its chronicity, recurrence, and resistance to treatment. Effective rosacea treatment requires repairing the skin barrier, reducing inflammation, and promoting vasoconstriction.

Aims: This study aims to evaluate the efficacy of topical ferulic acid in treating papulopustular rosacea and its impact on skin barrier function.

Methods: Sixty patients with mild to moderate papulopustular rosacea were selected from the Department of Dermatology at the Affiliated Hospital of Shandong Second Medical University between January 2023 and December 2023. Patients were randomly assigned to either a control group or an observation group, with 30 patients in each group. The observation group applied ferulic acid solution to the affected areas, while the control group used normal saline, both twice daily for 6 weeks. Both groups also received 0.1 g doxycycline hydrochloride tablets orally once daily. Skin lesions and skin barrier function were assessed using VISIA imaging and self-rating scales before and during treatment, and adverse reactions were recorded.

Results: After 6 weeks, both skin lesion assessments and self-assessment scores improved significantly from baseline, with greater improvement in the observation group compared to the control group (p < 0.05). Indicators of skin barrier function and VISIA imaging results demonstrated the efficacy of ferulic acid in treating rosacea. The total effective rate was significantly higher in the observation group (80.00%) compared to the control group (63.33%) (p < 0.05). In the observation group, nine patients (30.00%) experienced a greasy sensation initially, one patient (3.33%) reported tingling and itching, and no serious adverse reactions were observed.

Conclusions: Ferulic acid is effective as an adjuvant treatment for papulopustular rosacea, significantly improving skin lesions and repairing skin barrier function with minimal adverse reactions.

Background: Acne is a chronic inflammatory skin disease that negatively affects patients' quality of life. Increasing antibiotic resistance is making acne less responsive to treatment. Probiotics are live microorganisms that can provide health benefits by fighting pathogens and maintaining intestinal homeostasis and skin microbiome balance. This study investigates the effects of probiotics in the treatment of acne vulgaris.

Methods: In this randomized controlled clinical trial, 80 patients with moderate acne were divided into two groups of 40. All patients received the same topical treatment, which consisted of a daily antibacterial face wash and Adapalene gel every other night. The control group received one capsule of doxycycline (100 mg) daily, whereas the intervention group received one probiotic capsule daily in addition to doxycycline. Patients underwent photography of facial acne lesions, and treatment response was assessed using the global acne grading system (GAGS) and acne grading method at baseline, as well as during follow-up visits at 1, 2, and 3 months.

Results: The global acne grading system indicated that both groups showed improvement. However, analyses revealed that outcomes were significantly better in the doxycycline plus probiotics group for the forehead (p = 0.018), chin (p = 0.021), and nose (p = 0.021). No significant differences were observed for the left and right cheeks, back, and chest areas, with the mean GAGS score reduction between the two groups differing by only 2%. Treatment with probiotics significantly reduced the severity of lesions compared to the control group (p < 0.001). The acne grading method also indicated that the intervention group had a significantly better treatment response than the control group (p < 0.001). Furthermore, treatment with probiotics did not result in any side effects.

Conclusion: Probiotics can serve as an effective and safe treatment option, enhancing the outcomes of routine acne treatments, particularly for patients with acne on the forehead, chin, and nose.

Background: Recent research has demonstrated that Janus Kinase (JAK) inhibitors can be effective in treating refractory granulomatous diseases.

Case presentation: We report the case of a 50-year-old woman who developed a granulomatous reaction following a filler injection in her buttocks.

Management: The patient was treated with tofacitinib, and after 1 year of therapy, the stiffness and swelling resolved without any side effects.

Conclusion: Tofacitinib appears to be a viable option for the treatment of granulomatous reactions to fillers.
