CONSTITUTION:The objective cosmetic contains (a) a sphingoglycolipid and (B) a steroid glycoside and/or triterpenoid glycoside at a weight ratio (A/B) of 90/10-10/90 (preferably 70/30-30/70). The sum of A and B in the cosmetic is 0.05-90wt% (preferably 0.05-20wt). The cosmetic exhibits excellent moisture- retaining effect to skin.
