Photoaged skin results from various environmental factors, most importantly chronic sun exposure. Dyschromia and fine lines/wrinkles are common clinical manifestations of photodamaged skin.
This single-center clinical trial was conducted to assess the efficacy and tolerability of a new multifunctional facial primer (camouflage, broad-spectrum SPF 50, and a treatment for hyperpigmentation) when used by females with mild-to-moderate facial hyperpigmentation and fine lines due to photoaging over a course of 12 weeks.
Subjects were provided test material (Even Up-Clinical Pigment Perfector) and supporting products to use on their face and neck. Products were used according to specific application instructions. Clinical grading for efficacy and tolerability assessments were performed by an expert grader at baseline, baseline (post-application primer), week 4, week 8, week 12, and week 12 (post-application primer). Standardized digital photographs were taken, and self-assessment questionnaires were conducted.
Twenty-eight female subjects completed the 12-week trial. The facial primer improved scores for the appearance of hyperpigmentation and other photoaging parameters immediately after the first application. The treatment also showed a progressive improvement in the clinical assessment of hyperpigmentation and other photoaging parameters over the 12-week trial. These long-term benefits can be attributed to an improvement in the underlying skin condition. The facial primer was well tolerated. Subject questionnaires showed that the product was highly rated at all visits.
The facial primer was shown to be effective and well tolerated for immediate and long-term improvement in the appearance of mild-to-moderate hyperpigmentation and fine lines associated with photodamage when used over a 12-week period.
光老化皮肤是由多种环境因素导致的,其中最重要的是长期日晒。色素沉着异常和细纹/皱纹是光损伤皮肤的常见临床表现。
本单中心临床试验旨在评估一种新型多功能面部底霜(具有遮瑕、广谱防晒系数50以及治疗色素沉着过度功能)对因光老化导致面部有轻度至中度色素沉着过度和细纹的女性使用12周后的疗效和耐受性。
为受试者提供测试材料(Even Up临床色素完美修复霜)及配套产品用于面部和颈部。产品按照特定使用说明使用。由一名专业评分员在基线、涂抹底霜后基线、第4周、第8周、第12周以及第12周(涂抹底霜后)进行疗效和耐受性评估的临床分级。拍摄标准化数码照片,并进行自我评估问卷调查。
28名女性受试者完成了为期12周的试验。首次涂抹面部底霜后,色素沉着过度外观及其他光老化参数的评分即刻得到改善。在为期12周的试验中,该治疗方法在色素沉着过度及其他光老化参数的临床评估方面也呈现出逐步改善的趋势。这些长期益处可归因于潜在皮肤状况的改善。面部底霜耐受性良好。受试者问卷调查显示,在所有访视中该产品均获得高度评价。
研究表明,使用12周后,该面部底霜对于改善与光损伤相关的轻度至中度色素沉着过度和细纹的外观具有即时和长期效果,且耐受性良好。
