An oily external composition for skin of this invention is characterized in that comprising a complex powder (the surface of lipophilic base powder is covered with zinc oxide) and an oil component, wherein said complex powder is dispersed in said oil component, and wherein zeta-potential of said lipophilic base powder is negative value at pH on skin. It is preferable that zeta-potential of said lipophilic base powder is −10 mV or less at pH on skin. It is preferable that said lipophilic base powder is swelled in the condition of dispersing in oil.
