SCREENING METHOD FOR SUBSTANCE CAPABLE OF PROMOTING RECOVERY OF SKIN BARRIER FUNCTION TECHNICAL FIELD

摘要

The present invention provides a screening method for a substance capable of promoting recovery of skin barrier function, wherein the method comprises the steps of incubating caspase-14 and prosaposin in the presence of a candidate substance for the substance capable of promoting recovery of skin barrier function, and selecting the candidate substance as the substance capable of promoting recovery of skin barrier function when the degradation of prosaposin into saposin A is promoted significantly compared to a control substance.
