Skin external composition for enhancing skin barrier or moisturizing skin containing 7,3',4'-trihydroxyisoflavone

摘要

The present invention is 7,3 ', 4'-trihydroxy containing an isoflavone as the active ingredient relates to an external composition for skin, or for enhanced moisture barrier, and more particularly ortho-dihydroxy isoflavone of 7,3 ', peroxisome proliferator-activated in vivo by body containing 4'-trihydroxy isoflavone as well as to activate the receptor alpha (PPAR [alpha]) to increase the expression of the pillar green gene, trans glue Tommy tyrosinase 1 gene and hyaluronan synthase 2 increases the expression of genes inducing the differentiation of skin keratinocytes, and the skin barrier . strengthening relates to a skin external composition, and increasing the skin moisture content ; ortho-dihydroxy isoflavone, 7,3 ', 4'-trihydroxy Isoflavones, skin barrier strengthening, moisturizing, peroxisome proliferator-activated receptor body, painted pillars, trans glue Tommy tyrosinase, hyaluronic acid synthase
