METHOD OF SCREENING MATERIAL FOR IMPROVING DRY SKIN USING BLEOMYCIN HYDROLASE

摘要

The present invention relates to a method of screening material for improving dry skin and provides a method of screening material for improving dry skin comprising screening on the basis of a change in gene expression of bleomycin hydrolase by a candidate material, and a material for improving dry skin found by screening. In addition, provided is a composition for a skin preparation for external use, containing a liver X receptor activator which increases the gene expression of bleomycin hydrolase as an active ingredient. The screening method of the present invention can find an effective material for improving dry skin, and the composition improves dry skin and prevents loss of skin moisture, thereby restoring the skin barrier of the stratum corneum.
