Abstract: Disclosed herein is an electric puff, intended to rapidly and easily apply various types of cosmetics to a desired body part. A conventional puff is problematic in that a user must dab a surface covered with a cosmetic on a desired body part by hand, so that it is very complicated to do a user's makeup, and besides, it is difficult to keep a user's force constant, so that the cosmetic may not be evenly applied to the desired body part. The electric puff of this invention is constructed so that an actuating shaft is swingably coupled to an electric motor installed in a handle-shaped casing via a drive gear and a conversion gear and a puff head is coupled to an upper end of the actuating shaft, thus allowing a cosmetic to be evenly applied to a desired body part with a constant force although a user does not reciprocate the puff by hand, therefore allowing the user to rapidly and easily put on makeup, and allowing the cosmetic to be effectively applied to the desired body part.
