Abstract: A leakproof makeup applicator includes a main body, a rod, a collar and a bottle. The main body defines a receiving space therein. A power supply, a motor and a connector are disposed in the receiving space. The power supply electrically connects to the motor, and the connector is driven by the motor to be rotatable with respect to the main body. The rod connects to the connector concentrically and has a sealing sleeve disposed thereon. The bottle defines a liquid chamber and an opening formed at one end thereof. The opening has a plastic ring disposed on its inner periphery, in which the plastic ring defines a through hole. The rod inserts into the liquid chamber via the through hole. The sealing sleeve seals the through hole as the bottle and the collar are threadedly combined with each other.
