Abstract: Proposed is an RF electrode cartridge for skin beauty care treatment and a handpiece for skin beauty care treatment provided with the same. While being freely tilted for all ranges of 360 angle degrees around a ball joint part 140 within a radius thereof, the RF electrode body 120 moves in a state of being brought into close contact with the skin during the procedure, thereby preventing an accident that may occur while the RF electrode body 120 is spaced apart from the skin and in which damage to the skin tissue or burns to the skin may be caused. Accordingly, the present disclosure may greatly improve safety during a procedure.
