The aim of this study was to assess the effect of 2% bis-ethylhexyl hydroxydimethoxy benzylmalonate (HDBM; RonaCare(®) AP) as an active ingredient in the treatment of oily and blemished skin. This study was carried out as a randomized, placebo-controlled, single-blind study on 44 test subjects with blemished skin over a period of 8 weeks. Sebum measurement, skin inflammation/redness scoring by an expert, photographic documentation and a self-assessment with regard to skin improvement, and tests of skin compatibility and galenic characteristics were performed. Treatment with 2% HDBM resulted in a significant reduction of sebum excretion and showed efficacy against inflamed/red lesions also shown by photographic documentation. Efficacy and galenic performance of 2% HDBM were judged to be superior to the placebo emulsion. Additionally, 2% HDBM was well tolerated; approximately 80% of the test subjects rated the compatibility as good to very good.
本研究旨在评估 2%双乙基己基羟二甲氧苯甲酰基甲烷(HDBM;RonaCare(®)AP)作为一种活性成分在治疗油性和瑕疵皮肤方面的效果。该研究在 44 名有瑕疵皮肤的受试者中进行了为期 8 周的随机、安慰剂对照、单盲研究。通过皮脂测量、专家进行皮肤炎症/发红评分、摄影记录以及关于皮肤改善的自我评估,以及皮肤相容性和赋形剂特性测试进行了评估。使用 2% HDBM 治疗可显著减少皮脂分泌,并通过摄影记录显示出对发炎/发红病变的疗效。2% HDBM 的疗效和赋形剂性能被认为优于安慰剂乳液。此外,2% HDBM 的耐受性良好;大约 80%的受试者对其相容性评价为好到非常好。
