A Cosmetic Regimen Formulated to Address the Multi-Modal Pathogenesis of Rosacea Demonstrates Efficacy for Treating Facial Redness and Skin's Appearance.

BACKGROUND: The treatment of rosacea is complicated as there are multiple pathogenic factors in play resulting in a myriad of clinical signs and symptoms including facial redness. OBJECTIVE: The primary objective was to evaluate the efficacy and tolerability of a non-prescription anti-redness regimen in patients with rosacea. METHODS: Thirty subjects with rosacea-induced facial erythema were enrolled in this single site, monadic study. The test regimen consisted of a treatment serum, redness-reducing moisturizer, and sunscreen. The test products are formulated with ingredients curated to address the multifactorial pathogenesis of facial redness. Investigator and subject self-assessment for efficacy and tolerability were performed at baseline, weeks 4 and 8. Non-invasive assessments for facial redness and skin hydration were conducted at all time points. RESULTS: Investigator grading showed significant improvement in facial redness of 21% at week 4 and 32% at week 8. Skin's appearance improved as early as 4 weeks while at 8 weeks there was statistically significant improvement in fine lines 15%, radiance/brightness 37%, tactile roughness 44%, visual roughness 41%, and 26% in overall appearance. Non-invasive assessments showed statistically significant improvement in skin hydration of 28% at week 4 and facial redness of 21% by week 8. No tolerability issues were identified by the investigator. CONCLUSION: Patients with rosacea often turn to over-the-counter products to reduce facial redness and improve skin's appearance. In this study, a cosmetic skincare regimen designed to reduce facial redness demonstrated efficacy and tolerability in subjects with rosacea.

Treatment of Acne Vulgaris-Associated Post-Inflammatory Dyschromia With Combination of Non-Ablative Laser Therapy and Topical Antioxidants.

Acne can cause disfiguring sequelae, such as scarring, post-inflammatory erythema (PIE), and post-inflammatory hyperpigmentation (PIH). These post-inflammatory dyschromias pose a significant psychological burden on patients. This burden disproportionately affects skin of color (SOC) patients and can be the most distressing aspect of acne in SOC patients with skin types IV to VI. Multiple non-ablative lasers are used in the treatment of acne-related PIE and PIH. Combination therapies have shown promise in conditions such as rosacea, acne, and post-inflammatory dyschromia. Addressing both the inflammatory and scarring components of acne is key. Given the role of oxidation in the inflammatory cascade, including antioxidants could be an efficacious adjuvant with non-ablative lasers. This is a single-site, randomized, controlled clinical study of 25 subjects with skin types I to VI with facial PIE and/or PIH from acne. The primary objective was to investigate the clinical efficacy of non-ablative laser therapy followed by the topical application of Silymarin/Salicylic Acid/L-Ascorbic Acid/Ferulic Acid (SSAF) or control in the improvement in oily skin patients with facial PIE and PIH due to acne lesions. There was a statistically significant decrease in PIH and intralesional melanin in patients treated with a combination SSAF and non-ablative laser therapy. Improvement of both PIE and PIH was augmented in combination with SSAF and laser-treated patients compared with the laser-only group, with a concomitant increase in collagen density. This was even more strikingly marked in the SOC subjects, potentially providing an energy-based device (EBD)-based therapy in this population. Limitations of this study include small sample size and length of post-treatment follow-up. J Drugs Dermatol. 2024;23(9):769-773. doi:10.36849/JDD.8309.

Salp14 epitope-based mRNA vaccination induces early recognition of a tick bite.

Repeated exposure of animals to Ixodes scapularis ticks can result in acquired tick resistance (ATR). The first manifestation of ATR is erythema at the tick bite site, however, the specific peptide targets and mechanisms associated with this early aspect of ATR are not understood. In this study, we immunized guinea pigs with a lipid nanoparticle containing the mRNA encoding 25 amino acids in the carboxyl terminus of Salp14 (Salp14-C mRNA-LNP), an I. scapularis salivary protein. The animals produced high titers of IgG directed at the carboxyl terminus of Salp14. Guinea pigs immunized with Salp14-C mRNA-LNP and then exposed to I. scapularis, developed erythema at the tick bite site. Transcriptomics of the skin of guinea pigs at the I. scapularis bite sites elucidated selected pathways, including histamine activation, that are associated with the development of erythema. The study demonstrates that an mRNA vaccine encoding a small peptide can induce the initial phase of ATR in guinea pigs.

Oral administration of cysteine peptides attenuates UV-B-induced skin erythema and pigmentation in humans.

The oral administration of antioxidants may suppress UV-B-induced skin damage. HITHION YH-15, the extract of Torula yeast (Cyberlindnera jadinii), is rich in cysteine-containing peptides such as reduced and oxidized glutathione (GSH and GSSG), γ-glutamylcysteine (γ-Glu-Cys), and cysteinylglycine (Cys-Gly). These four constituents are termed cysteine peptides. In this study, we investigated the protective effects of cysteine peptides against UV-B in a randomized, placebo-controlled, double-blind, parallel-group study. A total of 90 healthy males and females aged 30-59 years were enrolled and randomized into two groups of 45 individuals each (cysteine peptides (48 mg/day) and placebo). Changes in UV-B-induced erythema and pigmentation were compared between groups after 5 weeks of test food intake. The minimal erythema dose (MED) significantly increased (*p = 0.019) in the cysteine peptides group compared to that in the placebo group, indicating suppression of UV-B-induced erythema. ΔL* value significantly increased (***p < 0.0001) in the cysteine peptides group compared to that in the placebo, indicating pigmentation suppression. We demonstrated that oral administration of cysteine peptides suppresses UV-B-induced erythema and pigmentation through multiple mechanisms. Thus, cysteine peptides may find use as nutricosmetics for maintaining skin health and well-being.UMIN Clinical Trials Registry ID: UMIN 000050157.

[Erythema and flu symptoms of a hunter with pre-existing conditions]. / Erythem und grippale Symptome bei einem Jäger mit Vorerkrankungen.

INTRODUCTION: A hunter with a history of oncology, flu-like symptoms and ring-shaped erythema was treated with doxycycline in an outpatient setting on suspicion of a tick-borne disease. After obtaining a positive Francisella tularensis serology, antibiotic treatment was continued for a total of 21 days, followed by freedom of symptoms and falling CRP, but without prompt serological follow-up. In contrast to the previously described tularemia cases in Switzerland, the article shows less pronounced local finding without palpable lymphadenopathy.

Fractional picosecond laser treatment of non-acne atrophic scars and scar erythema in Chinese patients.

BACKGROUND: Fractional picosecond lasers (FPL) are reported to be effective and safe for atrophic acne scars and post-acne erythema. However, there is no evidence regarding the effectiveness and safety of FPL treatment for non-acne atrophic scars and scar erythema among Chinese patients. METHODS: In this retrospective study, 12 Chinese patients with non-acne atrophic scars, including nine with scar erythema, were treated with one to three sessions of 1064 nm FPL treatment. Clinical improvement was objectively assessed through blinded evaluations by external physicians. A modified Manchester Scar Scale (mMSS) and the Clinician Erythema Assessment Scale (CEAS) were individually used to evaluate atrophic scars and scar erythema based on photographs. Physician-assessed and subject-assessed Global Aesthetic Improvement Scale (GAIS) were used to assess changes before and after FPL treatment. Patient satisfaction and adverse events were also documented. RESULTS: Total mMSS scores, as well as three parameters (color, distortion, and texture), were significantly decreased after FPL treatment, with a mean reduction of 3.18 ± 1.60 in total scores (p < 0.05). The CEAS scores were significantly reduced from 2.41 ± 0.98 before treatment to 0.41 ± 0.40 at the final visit (p < 0.05). Based on physician-assessed and subject-assessed GAIS scores, 11 (91.7%) patients were improved after FPL treatment. 33.3% of patients were very satisfied, and 41.7% were satisfied. No serious, prolonged (> 3 weeks) adverse events were observed. CONCLUSION: Our study suggests that 1064 nm FPL treatment may be a promising option for non-acne atrophic scars, especially with scar erythema. Further studies are needed to confirm our results.

Effects of neuromuscular taping form I on wound temperature and erythema in diabetic foot ulcer: a preliminary study.

OBJECTIVE: This study aimed to measure the effectiveness of neuromuscular taping (NMT) form I (a polyacrylate tape 0.6cm wide and 30cm long) on wound temperature and erythema in diabetic foot ulcers (DFUs) as an initial study in NMT intervention trials. METHOD: The study employed a quasi-experimental pretest and post-test design with a seven-day observation. The research sample was 38 patients with DFU grades 2 and 3. The sample was divided into two groups: the control group (n=19) and the intervention group (n=19). In wound care, the modern dressing was applied to both groups while NMT was applied to the intervention group in form I with 30cm long and 6mm wide strips, and on the proximal, distal and lateral sides. The wound bed temperature was measured with a non-contact infrared thermometer, and erythema was measured with Corel Photo-Paint X5 software (Corel Corp, Canada). Statistical analysis between the two groups was carried out using the Mann-Whitney test, independent t-test and Chi-squared test with p< 0.05 representing statistical significance. RESULTS: The preliminary results revealed that no statistically significant differences (p>0.05) were noted between the groups in sociodemographic or clinical characteristics, including age, body mass index, blood sugar, duration of diabetes, sex, smoking history, wound temperature and degree of erythema. Finally, it was also observed that, after seven days of application, NMT form I increased wound bed temperature, and reduced the level of erythema (p<0.05). CONCLUSION: In this study, NMT form I has been shown to increase the wound bed temperature and reduce the degree of erythema in DFUs.

Efficacy and safety of a topical skincare regimen containing CE Ferulic serum and resveratrol BE serum following ablative fractional CO2 laser treatment: A prospective, randomized, split-face, controlled trial.

BACKGROUND: Ablative fractional CO2 laser is widely used to address various skin problems, but the treatment often leads to adverse effects such as erythema, dyspigmentation, and extended recovery periods, negatively impacting patients' quality of life. OBJECTIVES: This study aimed to evaluate the efficacy and safety of a topical skincare regimen containing both CE Ferulic serum and Resveratrol BE night serum following fractional CO2 laser treatment in Chinese population. METHODS: In this randomized, investigator-blinded, split-face, controlled trial, individuals aged 18-65 undergoing ablative CO2 laser treatment were randomly assigned to apply CE Ferulic plus resveratrol BE serum (CEF-RBE) to either side of face and normal saline (NS) to the other, for 14 consecutive days. The primary endpoint was erythema index (EI) on day 14, with key secondary endpoints including scabbing detachment time, percentage changes in EI and melanin index (MI), skin hydration, transepidermal water loss, skin sebum content, oedema, and overall subject satisfaction. RESULTS: The study included 51 patients, of whom 29 (56.9%) were female, with a mean (SD) age of 29.8 (5.39) years. On day 14, the CEF-RBE side exhibited significantly lower EI than the NS side (308.9 vs. 325.3, p = 0.034). The median (IQR) time (days) for complete scabbing detachment at the CEF-RBE side was 6.0 (5.0-8.0) compared to 6.5 (5.0-9.0) at NS side (p = 0.018). Additionally, the CEF-RBE side showed a 7.4% decrease in MI from baseline to day 14, while the NS side experienced a 0.2% increase (Δ = -7.6%, p = 0.044). Throughout the 14-day follow-up, the CEF-RBE side consistently displayed higher skin hydration than the NS side. CONCLUSIONS: The study highlighted the benefits of incorporating CEF-RBE following laser treatment in reducing erythema and hyperpigmentation, promoting wound healing, and maintaining skin hydration, although limitations such as contamination and adherence issues should be considered.

Combined low-dose isotretinoin and long-pulsed nd: YAG laser in the treatment of post-acne erythema.

Post-acne erythema (PAE) is a bothering skin condition that emerges from inflammatory acne and persists after its resolution. It is characterized by telangiectasia and erythematous macules. the role of 1064-nm Nd: YAG when combined with low-dose isotretinoin in the acne erythema treatment. forty-eight PAE patients were involved in the study. They were divided into two groups; group (A) patients administering a low dose of oral isotretinoin (10 mg/day) and underwent a total of six two-week interval sessions of 1064 ND-YAG laser treatment, group (B) patients administering a low dose of oral isotretinoin (10 mg/day) only. All adverse effects experienced during the course of therapy were documented, and photos were taken before the start of the treatment and following the end of the treatment duration. Following the completion of the therapeutic intervention, a significant improvement in clinical condition was observed in both groups, with more improvement in group (A) compared to group (B) as evidenced by a notable improvement in the score on the Clinician Erythema Assessment Scale (CEAS) and also a significant decrease in the mean value of optical density of the erythema. combined 1064-nm Nd: YAG with low-dose isotretinoin may be an efficient and secure line in the PAE treatment. Also, the combined therapy had superior results when compared to low-dose isotretinoin alone.

Efficacy of fractional radiofrequency in the treatment of erythematous capillary rosacea: A split-face study.

OBJECTIVE: To assess the effectiveness and safety of treating erythematotelangiectatic rosacea using fractional radiofrequency (FRF). METHODS: Twenty patients with a confirmed diagnosis of erythema capillaris rosacea were selected, and one side of each patient's face was randomly assigned to receive FRF treatments for three to six times, with an interval of 2 weeks between each treatment. VISIA, dermoscopy, and the Clinician's Erythema Evaluation Scale (CEA) were applied to evaluate the efficacy of the treatment before and after the treatment, to record the VAS scores and adverse reactions, and to conduct a patient satisfaction survey. RESULTS: The characteristic counts and scores of red zone and porphyrin as assessed by VISIA test were significantly decreased, and the difference between the treated side and the pretreatment side was statistically significant (p < 0.05), and the efficacy of the treatment was statistically insignificant compared with the control side, except for the red zone and porphyrin which were statistically significant before and after the treatment (p > 0.05). By CEA score, the difference between the treated side after treatment and the control side was statistically significant (p < 0.05), and the difference between the treated side before and after treatment was statistically significant (p < 0.05); the difference between the control side before and after treatment was not statistically significant (p > 0.05). Dermatoscopic observation showed reduction in pore size, reduction of yellowish-white and black horn plugs within the pores, lightening of the red background and thinning and blurring of the capillary structure on the treated side of the skin compared to the control side, and the skin on the treated side showed the above mentioned changes before and after the treatment as well. The mean pain score of the subjects was obtained by VAS score 3.67 ± 0.90. Adverse effects included mild edema, erythema, and microscopic crusting; no long-term adverse effects were seen in all patients. The efficacy of FRF treatment was evaluated 1 month after the final treatment, and 85% of the subjects rated it as satisfactory, very satisfactory, and very satisfactory. CONCLUSION: FRF for the treatment of erythematous capillary dilatation rosacea is effective, safe, and suitable for clinical promotion.
