A method of treating a person's skin with a serum using an ultrasonic serum application device. The ultrasonic serum application device includes a handle, a paddle that is adapted to removably engage a proximal end of the handle, and an application surface. An ultrasonic vibrator positioned within the handle is operably associated with the application surface for transmitting ultrasonic vibrations to the application surface. The person's skin is coated with the serum and rubbed with the application surface such that the ultrasonic vibrations are transmitted to increase the effectiveness of the serum on the person's skin.
