The invention relates to a method, a system and a product for determining an ultrasonic energy focusing area, and belongs to the field of ultrasonic cosmetology. Determining energy density I; acquiring the output power P of the ultrasonic transducer; calculating an ultrasonic energy focusing area S and an ultrasonic energy focusing area radius r; acquiring the radius R of an acoustic beam emitting surface; calculating an ultrasonic beam rotation angle theta; acquiring a space coordinate of an acoustic beam emission point; calculating a space coordinate of a sound beam target point; acquiring a pulse repetition frequency fPRF of the ultrasonic transducer and an energy accumulation value W required by heating denaturation of the collagen; the number N of acoustic beams needing to be emitted to the acoustic beam target point T by each acoustic beam emission point is calculated; calculating the delay excitation time of each array element; and the array element matrix is sequentially activated according to the del
