Rosacea is a common, incurable skin barrier disorder characterized by relapses and remissions.
To evaluate the efficacy of Farmaka Rosacea Cream (FRC), a novel topical formulation for rosacea.
This single-center, open-label pilot study comprised a single-dose substudy in 20 healthy subjects and a long-term, repeat-dose substudy in 22 subjects with rosacea. The 2-hour, controlled, single-dose substudy assessed the soothing and reepithelialization properties of FRC after stripping-induced erythema based on the erythema index, transepidermal water loss, skin hydration, and clinical assessments of erythema. In the long-term substudy, subjects applied FRC twice daily for 8 weeks. Clinical assessments included vascular and pigmentary homogeneity and erythema and hemoglobin indices. Subjects completed questionnaires to assess FRC efficacy and cosmetic acceptability.
Greater reductions were seen in FRC-treated areas compared with untreated areas for the erythema index (-16% versus -8%; P<0.001) and mean transepidermal water loss (-35.8% versus -10.1%; P<0.001) 30 minutes after stripping. Significant improvements over untreated areas were maintained 2 hours after stripping. Skin hydration and clinical erythema assessments also indicated that FRC soothed rosacea symptoms and promoted skin reepithelialization. Erythema and hemoglobin indices were significantly reduced from baseline after 4 and 8 weeks of treatment. Clinically assessed parameters were significantly improved following FRC application. Subjects assessed FRC positively.
Improvement of rosacea symptoms was noted with FRC application. The main film-forming ingredients of FRC (trehalose, cholesterol, ceramide, and fatty acids), combined with other soothing and calming ingredients and ultraviolet filters, could explain its efficacy.
酒渣鼻是一种常见的、无法治愈的皮肤屏障疾病,其特点是病情反复。
评估一种新型酒渣鼻外用制剂Farmaka酒渣鼻乳膏(FRC)的疗效。
这项单中心、开放标签的试点研究包括在20名健康受试者中进行的单剂量子研究,以及在22名酒渣鼻受试者中进行的长期重复剂量子研究。在2小时的对照单剂量子研究中,基于红斑指数、经表皮水分流失、皮肤水合作用和红斑的临床评估,评估了FRC在剥脱性红斑后舒缓和促进再上皮化的特性。在长期子研究中,受试者每天两次涂抹FRC,持续8周。临床评估包括血管和色素均匀性以及红斑和血红蛋白指数。受试者完成问卷以评估FRC的疗效和美容可接受性。
在剥脱后30分钟,FRC治疗区域的红斑指数(-16%对-8%;P<0.001)和平均经表皮水分流失(-35.8%对-10.1%;P<0.001)相比未治疗区域有更大程度的降低。剥脱后2小时,与未治疗区域相比仍保持显著改善。皮肤水合作用和临床红斑评估也表明,FRC可舒缓酒渣鼻症状并促进皮肤再上皮化。治疗4周和8周后,红斑和血红蛋白指数较基线显著降低。应用FRC后,临床评估参数有显著改善。受试者对FRC的评价积极。
应用FRC可改善酒渣鼻症状。FRC的主要成膜成分(海藻糖、胆固醇、神经酰胺和脂肪酸),与其他舒缓和镇定成分以及紫外线过滤剂相结合,可以解释其疗效。
