A magnetic powder to be included in a cosmetic agent being removable by a magnetic attraction force from the cosmetic agent applied to the skin. The magnetic powder comprises a ferromagnetic ferrite, a mean volume particle diameter of 50 to 75 µm when determined from a particle size distribution obtained by a laser diffraction scattering method, a content of particles with a particle diameter of less than 37 µm of 15% by mass or less, and a content of particles with a particle diameter of 105 µm or more of 5% by mass or less. The magnetic powder preferably has a saturation magnetization of 80 Am2/kg or more.
