Abstract:
PURPOSE: A composition is provided to promote the migration of melanocytes in skin and hair, to relieve and treat a lesion in hypopigmentary diseases such as vitiligo and grey hair, and to quickly and simply screen the skin vitalizing substance. CONSTITUTION: A composition for promoting adult melanocyte migration contains chemokine which is selected from a group consisting of CTACK, I-TAC, Lptn, PARC, SDF1, and TARC. The composition is used for treating hypopigmentary diseases. A kit for detecting a skin vitalizing substance contains a chemokine-specific antibody, a secondary antibody, a chromogenic label, and skin cells. The kit is used for detecting the skin vitalizing substance by screening a material which regulates expression of chemokine in skin cells. A method for detecting skin vitalizing substance comprises: a step of treating the skin cells with a candidate material and identifying expression of chemokine; and a step of isolating and purifying a material which reduces expression of chemokine.

Abstract:
PURPOSE: A method for screening a material for treating dry skin is provided to prevent skin moisturizing and to recover skin barrier. CONSTITUTION: A method for screening a material for treating dry skin comprises a step of screening candidate materials based on expression change of bleomycin hydolase(BH) gene. The gene expression level is measured by PCR. An external use skin composition contains LXR activator which enhances BH gene expression level as an active ingredient. The composition is used for treating dry skin or moisturizing skin.
