The problem addressed by the present invention is to provide a composition for external application to the skin containing a salt-resistant polymer and an acidic polysaccharide. The composition does not cause balling up of a cosmetic on the skin when a cosmetic is applied on the composition after the composition is applied on the skin. The composition for external application to the skin contains (A) a salt-resistant polymer, (B) an acidic polysaccharide, and (C) an amphipathic compound represented by the general formula (1): Z—[O-{(EO)a(PO)b}-(AO)c—H]n (1) wherein n, a, b, and c each represent a specific number; and Z, EO, PO, and AO each represent a specific group.本發明之課題為以提供一種皮膚外用組成物,其係在包含耐鹽性高分子及酸性多醣類之皮膚外用組成物中,即使是將其適用後並重複塗布化妝料時,亦不會產生彩妝起皺之情形。本發明為一種皮膚外用組成物,其係包含:(A)耐鹽性高分子、(B)酸性多醣類、與(C)以下述一般式(1)所表示的兩親媒性化合物:Z-〔O-{(EO)a(PO)b}-(AO)c-H〕n (1)(式中,n、a、b及c係表示特定的數,Z、EO、PO及AO係表示特定的基)。
