Abstract

The purpose of this study was to compare the effectiveness of 1% colloidal oatmeal with 100% petrolatum in improving the skin barrier in patients with psoriasis vulgaris. This research method is a randomized, single-blind, pre and posttest design controlled trial involving patients with mild/moderate/severe psoriasis vulgaris at DR. Kariadi Hospital Semarang, Indonesia. The subjects of the study were divided into 2 groups, namely 1% colloidal oatmeal and 100% petrolatum. Evaluation was carried out by comparing the TEWL values between day 0 and day 28. The analysis was carried out using independent T-tests, Mann Whitney, and Wilcoxon. The results were significant if p<0.05 Results Topical administration of 1% colloidal oatmeal or 100% petrolatum could lower the TEWL value in each study group (p<0.001; p=0.006 respectively). ΔTEWL evaluation showed a significantly greater decrease in TEWL in the 1% colloidal oatmeal group (p=0.003). No complaints during use were reported in the 1% colloidal oatmeal group. Conclusion: Topical application of 1% colloidal oatmeal is more effective than 100% petrolatum as a moisturizer in improving the skin barrier in patients with psoriasis vulgaris without complaints.
