The development of topical cosmetic anti-aging products is becoming increasingly sophisticated. This is demonstrated by the benefit agents selected and the scientific approaches used to identify them, treatment protocols that increasingly incorporate multi-product regimens, and the level of rigor in the clinical testing used to demonstrate efficacy. Consistent with these principles, a new cosmetic anti-aging regimen was recently developed. The key product ingredients were identified based on an understanding of the key mechanistic themes associated with aging at the genomic level coupled with appropriate in vitro testing. The products were designed to provide optimum benefits when used in combination in a regimen format. This cosmetic regimen was then tested for efficacy against the appearance of facial wrinkles in a 24-week clinical trial compared with 0.02% tretinoin, a recognized benchmark prescription treatment for facial wrinkling. The cosmetic regimen significantly improved wrinkle appearance after 8 weeks relative to tretinoin and was better tolerated. Wrinkle appearance benefits from the two treatments in cohorts of subjects who continued treatment through 24 weeks were also comparable.
局部用化妆品抗老化产品的研发正变得越来越复杂。这体现在所选用的功效成分、用于识别这些成分的科学方法、越来越多地采用多产品方案的治疗方案,以及用于证明疗效的临床试验的严格程度上。基于这些原则,最近开发了一种新的化妆品抗老化方案。关键产品成分是在了解基因组水平上与衰老相关的关键机制主题并结合适当的体外测试的基础上确定的。这些产品设计为以方案形式联合使用时能提供最佳效果。然后,在一项为期24周的临床试验中,将这种化妆品方案与0.02%维甲酸(一种公认的用于治疗面部皱纹的基准处方药物)进行比较,测试其对改善面部皱纹外观的功效。与维甲酸相比,该化妆品方案在8周后显著改善了皱纹外观,且耐受性更好。在持续治疗24周的受试者群体中,两种治疗方法在改善皱纹外观方面的效果也相当。
