It is intended to provide an oily skin preparation for external use in which a powder is well dispersed in an oil and which has an excellent effect of improving/preventing skin roughness. Namely, an oily skin preparation for external use which comprises: a complex powder composed of a lipophilic powder having zinc oxide-coated surface; and an oily component in which the complex powder is dispersed; characterized in that the hydrophilic powder has a negative &zgr potential at the pH value on the skin. It is particularly favorable that the &zgr potential of the hydrophilic powder at the pH value on the skin is -10 mV or lower. It is also favorable that the lipophilic powder swells in the step of the dispersion in the oil. This skin preparation for external use is usable as an agent for improving skin roughness and an agent for caring sensitive skin.
