Abstract: A lipolysis radiation paddle (2) comprises a plurality of lipolysis radiation transducers (14) mounted in a base (20). The base (20) has a lower portion (21), and a pair of side portions (26) extending upwardly from respective sides of the lower portion (21). The lower portion (21) is shaped to fit under the jaw (51) of a user (50) of the paddle (2), and has a front end (22) shaped to receive the chin (52) of the user (50). The side portions (26) are each shaped to extend to and along respective sides of the jawline (53) of the user (50). The transducers (14) are directed inwardly towards the skin in proximity to the paddle (2).
