An aqueous pigment dispersion that can be prepared without using a powerful pulverizer, has high dispersibility, does not cause aggregation over time, has excellent dispersion stability, or has good redispersibility even when settled; Provided is a skin external preparation excellent in dispersibility and dispersion stability. An aqueous pigment dispersion contains 1) an inorganic pigment, 2) a nonionic surfactant, 3) an acid and 4) an alkali, and either one of the acid and the alkali is added. Then, after dispersing the inorganic pigment, the other of acid and alkali is added, and the skin external preparation contains this aqueous pigment dispersion. |
