Abstract: The device is used for cosmetic and relaxation treatment involving physical factors acting synergistically, including magnetic field, electrostimulation and photostimulation. The device has a plurality of magnets mounted on a rotor, which is mounted on a shaft driven by a motor. The motor and the rotor are within a housing. The rotor and the magnets extend close to an aperture in the housing and preferably closed by a device head. In use, when the motor is off, the magnets generate a static magnetic field. When the motor is on, the magnets generate a dynamic magnetic field. Such magnetic fields have benefic relaxing effects over the body by improving microcirculation of blood vessel. The device may also comprise electrodes and light emitting diodes mounted on its head and connected to a generator of electrical impulses for electrostimulating and photostimulating the body. This device, preferably made of plastic material, is of light weight and has the advantage of being portable.
