Abstract: The present invention relates to cosmetic composition having an improved smearing property. The cosmetic composition according to the present invention is directed to a water-in-oil type cosmetic composition containing a film former in an external phase, the composition being characterized by further containing a thickener in an internal phase. The thickener serves to form a kind of a bridge between the skin and the film former in an external phase, of which the affinity with the skin may deteriorate. According to the present invention, the smearing of the cosmetic composition can be improved more pragmatically and effectively by a combination with an external-phase film application manner of the prior art.
