OBJECTIVES: Batik dyes contain irritant chemicals that increase the risk of skin barrier disruption. This study aims to determine the effect of Centella asiatica and ceramide in transepidermal water loss (TEWL), hydration of the stratum corneum and skin acidity (pH).
METHODS: This was a double blind clinical trial of 30 Indonesian batik workers who suffered from skin dryness, but had no clinical manifestation of contact dermatitis. Subjects were given cream containing C. asiatica or ceramide that formulated and randomly labeled by manufacturer (PT Paragon Technology and Innovation). Both subjects and researchers were blinded to the type of the cream. Cream was applied to the hands and arms twice a day. Biological function of the skin (TEWL, stratum corneum hydration level, and skin acidity) was examined by Cutometer dual MP-580. Baseline was recorded in the first examination, followed by second and third examinations at two and four weeks after treatment.
RESULTS: After four weeks treatment, there were significant improvement of C. asiatica application in evaluation of corneometer palmar (p=0.007; CI 95%), corneometer dorsum (p=0.001; CI 95%), and skin acidity dorsum (p=0.017; CI 95%). Ceramide application also gave significant improvement of corneometer palmar (0.038; CI 95%), skin acidity palmar (p=0.001; CI 95%), TEWL dorsum (p=0.023; CI 95%), corneometer dorsum (p=0.002; CI 95%) and skin acidity dorsum (p=0.011; CI 95%). There were no significant differences of C. asiatica effectiveness compared to ceramide in skin barrier improvement.
CONCLUSIONS: C. asiatica and ceramide can improve skin barrier hydration in order to prevent the risk of contact dermatitis in batik workers.
