Efficacy and safety of intense pulsed light in rosacea: A systematic review.

Background Rosacea is a chronic inflammatory disease of the skin characterised by facial erythema, oedema, telangiectasias, papules, pustules and nodules. There is a paucity of effective therapeutic modalities for the management of rosacea. Intense Pulsed Light (IPL), a modality in which flash lamps installed in an optical treatment device (head or tip) with mirrors to reflect light, has in recent times gained popularity in the management of this condition. Aim This systematic review aims to evaluate the efficacy, safety and adverse effects of IPL treatment for rosacea. Methods This systematic review was conducted in accordance with the Preferred Reporting Item for Systematic Reviews and Meta-Analysis. The electronic databases searched were Medline, PubMed and Scopus databases. The Risk of bias in non-randomised studies of interventions (ROBINS-I) and risk-of-bias tools for randomised trials (RoB-2) was employed to assess the risk of bias. Results Of a total of 233 articles retrieved from Medline, Scopus and PubMed databases, 14 studies qualified for final analysis. The studies included patients with Fitzpatrick skin types I to IV, with ages ranging from 15 to 78 years. Although the included studies showed heterogeneity between the parameters used, most studies demonstrated positive effects of IPL treatment on telangiectasia and erythema in rosacea and that the adverse effects presented were transitory. Limitation The methodological quality of the included studies was poor. Conclusion Although most studies showed the efficacy of IPL in the treatment of rosacea, the poor quality of the studies was of concern.

Review of laser and energy-based devices to treat rosacea in skin of color.

The prevalence of rosacea in skin of color (SOC) populations is estimated to be as high as 10% in some countries. Traditionally, intense pulsed light (IPL) and pulsed dye laser (PDL) have been the laser and energy-based devices (EBDs) used to treat rosacea. However, not all laser and EBDs are safe for SOC (Fitzpatrick skin types IV-VI) due to increased absorption of energy in pigmented skin and increased risk of post-inflammatory hyperpigmentation and scarring. This review summarizes the use of the top seven laser and EBDs for treating rosacea in SOC.

Clinical efficacy of 595 nm pulsed dye laser in combination with supramolecular salicylic acid in the treatment of rosacea.

OBJECTIVE: This research was aimed at ascertaining the clinical effects of 595 nm pulsed dye laser (PDL) in combination with supramolecular salicylic acid (SSA) in the treatment of rosacea. METHODS: Eighty-four patients with rosacea were selected, of which 42 patients treated with PDL alone were considered as the control group, and 42 patients treated with 595 nm PDL in combination with 30% SSA were regarded as the observation group. The treatment continued for 4 months in the two groups. Clinical symptom scores, skin barrier function indicators, serum inflammatory factors, Acne⁃QOL scores and adverse reactions between the two groups were compared. RESULTS: After treatment, levels of inflammatory factors, clinical symptom scores, transdermal water loss, and oil volume were decreased, and epidermal water content and Acne-QOL scores were increased in both groups (all P < 0.05), and the changes in the observation group were more pronounced versus the control group (all P < 0.05). The difference in the incidence of adverse reactions was not statistically significant between the two groups (P > 0.05). CONCLUSION: 595 nm PDL in combination with SSA is safe in the treatment of rosacea.

Therapeutic strategies focusing on immune dysregulation and neuroinflammation in rosacea.

Rosacea is a complex inflammatory condition characterized by papulopustular lesions and erythema on the central face for which there is no cure. The development of rosacea is influenced by both external triggers and genetics, but the common pathophysiology is overactivation of the immune system. Here, we review the current data on proinflammatory cytokines and dysregulation of the neurovascular system as targetable components of rosacea. Amelioration of cutaneous and gastrointestinal dysbiosis and other external factors impacts the immune state and has been observed to improve rosacea. While multiple treatments exist, many patients do not achieve their goals for rosacea control and highlights an unmet need for dermatologic care. Current interventions encompass topical/oral drugs, light devices, and avoidance of triggers management. Additional understanding of the underlying pathogenesis may help us develop novel targeted therapeutic strategies to improve rosacea.

A two-center randomized controlled trial of a repairing mask as an adjunctive treatment for mild to moderate rosacea.

OBJECTIVE: To investigate the efficacy and safety of a repairing mask as an adjunctive treatment for skin barrier maintenance of mild to moderate rosacea. METHODS: Patients with rosacea were recruited in this dual center randomized controlled trial from November 2019 to December 2021. A total of 64 patients were included and randomized into two groups at a ratio of 3:1 into a mask group (n = 47) and a control group (n = 17). Patients in the mask group received treatment with Dr. Yu Centella asiatica repairing facial mask three times weekly for a duration of 6 weeks. All participants were instructed to continue their regimen of 50 mg oral minocycline twice daily and to apply Dr. Yu Intensive Hydrating Soft Cream twice daily. The primary endpoint of this study was the Investigator Global Assessment (IGA) score. RESULTS: A total of 54 patients completed this trial, with 41 in the mask group and 13 in the control group. After using this facial mask for 3 and 6 weeks, the IGA, facial skin dryness, facial flushing, and severity of skin lesion in the mask group showed significantly improvement (p < 0.05). Moreover, the change in the delta degree of skin flushing was significantly higher than that in the control group (p = 0.037). Throughout the study, no adverse events were reported in either group of participants. CONCLUSION: The Dr. Yu Centella asiatica repairing facial mask, as an adjunctive treatment of rosacea, appears to effectively repair and protect the skin barrier, alleviate cutaneous symptoms of rosacea, and is both efficacious and safe for patient use.

Rosacea: Common Questions and Answers.

Rosacea is a chronic inflammatory skin disease of the central face, affecting 5% of the population. The exact etiology is unknown. A diagnosis is made based on the updated 2017 National Rosacea Society Expert Committee guidelines, including fixed erythema, phymatous changes of skin thickening due to sebaceous gland hyperplasia and fibrosis, papules, pustules, telangiectasia, and flushing. Delays in an accurate diagnosis and treatment may occur in skin of color due to difficulty visualizing erythema and telangiectasia. The daily use of sunscreen, moisturizers, and mild skin cleansers and avoidance of triggers are essential aspects of maintenance treatment. Effective topical treatment options include alpha-adrenergic receptor agonists for flushing and ivermectin, metronidazole, and azelaic acid for papules and pustules. Systemic treatments include nonselective beta blockers for flushing, low-dose doxycycline, and isotretinoin for papules and pustules. Rosacea can significantly affect a patient's emotional health and quality of life. A referral for care is recommended for fixed phymatous changes and ocular rosacea.

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.

Efficacy and safety comparison between pulsed dye laser and intense pulsed light configured with different wavelength bands in treating erythematotelangiectatic rosacea.

Previous clinical studies have shown that pulsed dye laser (PDL) and intense pulsed light (IPL) are effective for treating erythematotelangiectatic rosacea(ETR). This article aims to compare the efficacy and safety of PDL and IPL at three different wavelength bands (broad-band, single-narrow-band, and dual-narrow-band) in treating ETR. Sixty subjects with ETR were randomly categorized into four groups and received one of the following laser treatments: PDL (595 nm), IPL with Delicate Pulse Light (DPL, 500-600 nm), IPL with M22 590 (590-1200 nm), or IPL with M22 vascular filter (530-650 nm and 900-1200 nm). Four treatment sessions were administered at 4-week intervals, with one follow-up session 4 weeks after the final treatment. The efficacy of the four lasers was evaluated by comparing the clinical symptom score, total effective rate, VISIA red area absolute score, and RosaQoL score before and after treatment. The safety was evaluated by comparing adverse reactions such as pain, purpura, erythematous edema, and blister. All 60 subjects completed the study. Within-group effects showed that the clinical symptom score, VISIA red area absolute score, and RosaQoL score of all four groups were significantly reduced compared to before treatment (p < 0.001). Between-group effects showed no statistically significant difference among the four laser groups. Safety analysis showed that all four lasers were safe, but the incidence of blister was higher in the M22 vascular group. Nonpurpurogenic PDL, DPL, M22 590, and M22 vascular were equally effective in treating ETR and were well-tolerated. ClinicalTrial.gov Identifier: NCT05360251.

Challenges and real-world solutions for adoption of holistic skincare routine (cleansing, treatment, moisturization, and photoprotection) in acne, rosacea, atopic dermatitis, and sensitive skin: An expert consensus.

BACKGROUND: While treatment is a definitive therapeutic component in the management of inflammatory skin conditions, adjunctive skin care comprising of appropriate cleansing, moisturization, and photoprotection are just as important. Cleansing, treatment, moisturization, and photoprotection (CTMP) constitute the four major components of holistic skincare routine for dermatological conditions. However, inadequate patient understanding of the condition, limited resources for physicians, and insufficient time for patient education during busy dermatological consultations are the main obstacles to establishing a holistic skincare routine in the real world. AIMS: This study aimed to identify key challenges in the implementation of a holistic skincare routine, and offer practical guidance to physicians to improve adoption in the management of acne, atopic dermatitis, rosacea, and sensitive skin syndrome. METHODS: An expert panel comprising of nine dermatologists from Australia, China, Hong Kong, Taiwan, India, Philippines, Singapore, South Korea, and Thailand convened to develop consensus statements to stimulate real-world adoption of holistic skincare routine in acne, rosacea, atopic dermatitis, and sensitive skin syndrome using the Delphi approach. RESULTS: Consensus was defined as ≥80% of panel rating statement as ≥8 or median rating of ≥8. The final statements were collated to develop consensus recommendations to encourage adoption of holistic skincare routine. CONCLUSION: Promoting patient education on the skin condition, training support staff in patient counseling, and offering physician training opportunities are the key strategies to encourage real-world adoption of CTMP as a holistic skincare routine. The consensus recommendations presented here should be considered in all dermatology patients to accomplish the ultimate goals of improved treatment outcomes and patient satisfaction.

A Review of Intense Pulsed Light in the Treatment of Ocular Rosacea.

INTRODUCTION: Ocular rosacea is an underdiagnosed form of rosacea that may occur with or without typical cutaneous signs of rosacea. One of the common manifestations is dry eyes. Although the use of intense pulsed light (IPL) in the treatment of rosacea-related dry eyes has been reported, a recent review is lacking. METHODS: A scoping review was performed to summarize the efficacy of IPL in the treatment of ocular rosacea. RESULTS: Five articles were included, representing 108 patients, with a mean age of 58.4 years. Based on available data, 59.2% (n = 58/98) were female. The studies detailed the use of IPL in combination with meibomian gland expression treatment. Overall, 91% (n = 89/98) of patients with ocular rosacea treated with IPL had a partial response and 9% (n = 9/98) had no response. IPL therapy did not lead to complete recovery in any of the included patients. One participant experienced an adverse event across the included studies. CONCLUSIONS: IPL is a promising treatment modality for ocular rosacea, as demonstrated by its ability to relieve dry eye symptoms with limited adverse events. Further research into this novel treatment is necessary to ascertain its role in the management of ocular rosacea.

Rosacea treatment with 532 nm KTP versus 595 nm pulsed dye laser-A prospective, controlled study.

BACKGROUND: Pulsed-dye lasers (PDL) are one of the standard therapies for rosacea, but alternatives are needed. AIMS: To compare the efficacy and safety of the variable-sequenced, large-spot 532 nm KTP laser to the 595 nm PDL in treating rosacea. MATERIALS AND METHODS: A prospective, controlled, evaluator-blinded study. Patients were treated with either a KTP or PDL with 1-3 sessions at intervals of 6-8 weeks. A follow-up visit was scheduled on Week 6 post-treatment. Clinical outcome was assessed by computer-assisted analysis and by patients and two blinded dermatologists. Pain intensity during treatment and adverse events were documented. RESULTS: Forty-five patients (mean age 51 years) were allocated in a 2:1 ratio to either the KTP or PDL. Erythema in both treatment arms decreased significantly (p < 0.01). Clinical evaluation revealed high improvement. Mean pain intensity was significantly lower with the KTP (2.5/10) than with the PDL (4.1/10). Both lasers showed a good safety profile. Relevant purpura was only seen in the PDL group. CONCLUSIONS: Both the variable-sequenced, large-spot KTP and the PDL demonstrated comparable efficacy in treatment of rosacea. Regarding safety, the KTP exhibited fewer post-treatment reactions. The KTP might serve as a potential alternative to PDL in the treatment of rosacea.

Rosacea Core Domain Set for Clinical Trials and Practice: A Consensus Statement.

Importance: Inconsistent reporting of outcomes in clinical trials of rosacea is impeding and likely preventing accurate data pooling and meta-analyses. There is a need for standardization of outcomes assessed during intervention trials of rosacea. Objective: To develop a rosacea core outcome set (COS) based on key domains that are globally relevant and applicable to all demographic groups to be used as a minimum list of outcomes for reporting by rosacea clinical trials, and when appropriate, in clinical practice. Evidence Review: A systematic literature review of rosacea clinical trials was conducted. Discrete outcomes were extracted and augmented through discussions and focus groups with key stakeholders. The initial list of 192 outcomes was refined to identify 50 unique outcomes that were rated through the Delphi process Round 1 by 88 panelists (63 physicians from 17 countries and 25 patients with rosacea in the US) on 9-point Likert scale. Based on feedback, an additional 11 outcomes were added in Round 2. Outcomes deemed to be critical for inclusion (rated 7-9 by ≥70% of both groups) were discussed in consensus meetings. The outcomes deemed to be most important for inclusion by at least 85% of the participants were incorporated into the final core domain set. Findings: The Delphi process and consensus-building meetings identified a final core set of 8 domains for rosacea clinical trials: ocular signs and symptoms; skin signs of disease; skin symptoms; overall severity; patient satisfaction; quality of life; degree of improvement; and presence and severity of treatment-related adverse events. Recommendations were also made for application in the clinical setting. Conclusions and Relevance: This core domain set for rosacea research is now available; its adoption by researchers may improve the usefulness of future trials of rosacea therapies by enabling meta-analyses and other comparisons across studies. This core domain set may also be useful in clinical practice.

Rosacea: Pathogenesis and Therapeutic Correlates.

Rosacea is a chronic inflammatory condition of which there is no cure. The pathogenesis of rosacea is likely multifactorial, involving genetic and environmental contributions. Current understanding suggests that pro-inflammatory pathways involving cathelicidins and inflammasome complexes are central to rosacea pathogenesis. Common rosacea triggers modulate these pathways in a complex manner, which may contribute to the varying severity and clinical presentations of rosacea. Established and emerging rosacea treatments may owe their efficacy to their ability to target different players in these pro-inflammatory pathways. Improving our molecular understanding of rosacea will guide the development of new therapies and the use of combination therapies.

Patients' testimonies, feelings, complaints and emotional experiences with dermatoses on open social media: The French infodemiologic patient's free speech study.

BACKGROUND: Dermatoses represent a significant burden. Patients and their caregivers can turn to social media and digital communities to exchange with each other. These public exchanges constitute real-life data that can be analysed to better understand the patients' feelings and expectations, and the daily difficulties encountered. OBJECTIVE: An infodemiologic study of public testimonies of patients and caregivers related to five dermatoses: eczema, rosacea, vitiligo, acne and psoriasis, over a 3-year time frame (September 2018 to September 2021) in France. To identify main topics of discussion, encountered difficulties and unmet medical needs. METHODS: Data extraction was performed based on a list of pertinent keywords. Web-users' profiles were determined by a specifically trained machine learning algorithm. Encountered difficulties were identified by manual annotation based on a standardized search grid. Co-occurrence analysis of difficulties allowed contextualization of challenges and unmet needs for each dermatosis. RESULTS: A total of 20,282 messages coming from 16,800 web users was extracted. The main topics of discussion were 'Impact on self- image and self-confidence' (23.6%), 'Generic discussion about therapeutics' (23.3%) and 'Burden of others' gaze' (12.8%). The top three mentioned difficulties for the five targeted dermatoses were similar and focused on 'Fear of/and management of symptoms', 'Impact on/and mood management' and 'Damaged self-image'. CONCLUSION: This infodemiologic study highlighted the real-life management of five skin diseases by patients and their caregivers, who turned to social networks to openly express their suffering and seek solutions. The joined analysis of the five diseases enabled a common comprehension of what it is to live with a skin disease, from a patient-centric point of view. The specific analysis of each patient group objectified specific challenges, and main unmet medical needs.

Rosacea treatment with mussel adhesive protein delivered via microneedling: In vivo and clinical studies.

BACKGROUND: Rosacea is a prevalent chronic dermatological condition marked by facial inflammation and erythema, significantly compromising the quality of life for affected individuals. Current treatment methods for rosacea are not considered ideal because of the complex etiology of the disease. Mussel adhesive protein (MAP) is a glycoprotein derived from the foot gland of mussels. The protein exhibits anti-inflammatory properties, relieves skin itching, and promotes wound healing. AIMS: We aimed to explore the feasibility of using MAP administered via microneedle delivery for treating rosacea and the potential molecular mechanism involved. MATERIALS AND METHODS: The therapeutic effect and mechanism of MAP microneedle delivery in an LL-37-induced rosacea-like mouse model were observed using morphological and histological methods. Twenty-seven patients with erythematotelangiectatic rosacea (ETR) underwent treatment once every 1 month, with three treatments constituting one treatment course. The therapeutic effect was evaluated by comparing the clinical images taken at baseline, after the first treatment course, and after the second treatment course. The red value, CEA, and GFSS score were also calculated. RESULTS: In response to the microneedle delivery of MAP, innate immunity, inflammatory infiltration, and abnormal neurovascular regulation improved significantly in rosacea-like mice. In the clinical experiments, the microneedle delivery of MAP significantly improved the symptoms of erythema, flushing, and telangiectasia in patients with ETR, and no obvious adverse reactions were observed. CONCLUSIONS: MAP delivered by microneedling is effective and safe for treating ETR.

Diagnosis and Management of Common Inflammatory Skin Diseases in Older Adults.

Inflammatory skin conditions affect people of all ages, genders, and races. These common conditions are frequent causes of visits to the dermatologist. The geriatric population is often afflicted by these conditions because many are chronic and relapsing diseases. These inflammatory conditions include but are not limited to psoriasis, atopic dermatitis, contact dermatitis, seborrheic dermatitis, rosacea, and Grover disease. Chronic inflammatory skin conditions place a large burden on the health care system in the United States and have many associated comorbidities. This article discusses these inflammatory dermatoses that affect the geriatric population and common therapeutic options.

Narrow-Band Intense Pulsed Light as Treatment for Erythematotelangiectatic Rosacea: A Retrospective Study.

BACKGROUND: Erythematotelangiectatic rosacea can be successfully treated using various laser and light-based devices. However, the use of narrow-band intense pulsed light for the treatment of erythematotelangiectatic rosacea has not been investigated in detail. This retrospective study aimed to analyze the clinical efficacy of narrow-band intense pulsed light (500-600 nm) for the treatment of erythematotelangiectatic rosacea among Chinese individuals.  Methods: Patients with erythematotelangiectatic rosacea who had completed 3 sessions of treatment with narrow-band intense pulsed light and follow-up from July 2016 to December 2018 were retrospectively evaluated. Clinical improvement was assessed by 2 blinded dermatologists based on photographs obtained at each follow-up visit using the clinician erythema assessment scale and 5-grade scale. RESULTS: Forty-five patients with erythematotelangiectatic rosacea treated with narrow-band intense pulsed light were included in this study. The effectiveness and excellent rates after 3 treatment sessions were 68.9% and 35.6%, respectively. An average of 2 treatment sessions was required among patients who achieved good or excellent clearance of erythema and telangiectasia. Except for transient erythema and edema, no severe adverse effects were observed. CONCLUSIONS: Narrow-band intense pulsed light is a safe and effective treatment for erythematotelangiectatic rosacea. Even with a small number of treatment sessions, narrow-band intense pulsed light can deliver a significant therapeutic effect, which may be applicable in clinical practice.
