	At the high temperature（Summer） ○Enhancing of capillary・・・It flushes. ・Circulation of the blood is excellent. ○A secretion increase in sweat・・・・・Prickly heat・Make-up crumble At the low temperature（Winter） ○Shrinkage of capillary・・Poor circulation・Skin depression ○A secretion decrease in sweat・・・・・Dryness・Wrinkle
