The present invention relates to cosmetic compositions comprising (A) at least one amide derivative having a specified formula; and (B) at least one ingredient selected from the group consisting of (B-1) polyhydric alcohols, (B-2) vegetable extracts and (B-3) organic acids or salts thereof. The compositions can enhance the water-retaining ability of the horny layer and have excellent effects for improving skin roughness and preventing the formation of wrinkles.
