Abstract: A muscle electrostimulation device is configured to apply electrostimulation to a muscle. The electrostimulation includes burst waves each including a pulse group output period and any of pulse group output suspension periods in an alternately repeated manner. In the pulse group output period, rectangular wave pulse signals are output, with output stop times being inserted between the rectangular wave pulse signals. In the pulse group output suspension periods, output of pulse signals stops for a time longer than the output stop times. The repeated burst waves each include rectangular wave pulse signals having positive polarity, and rectangular wave pulse signals having negative polarity.

Abstract: The facial muscle exercising device (20) is provided with an elastically deformable bending portion (21) and a mouth-held portion (24), which is installed at the center of the bending portion (21) and held by the lips. The mouth-held portion (24) is located outside an edge portion of the bending portion (21).

Abstract: A magnetic powder to be included in a cosmetic agent being removable by a magnetic attraction force from the cosmetic agent applied to the skin. The magnetic powder comprises a ferromagnetic ferrite, a mean volume particle diameter of 50 to 75 ?m when determined from a particle size distribution obtained by a laser diffraction scattering method, a content of particles with a particle diameter of less than 37 ?m of 15% by mass or less, and a content of particles with a particle diameter of 105 ?m or more of 5% by mass or less. The magnetic powder preferably has a saturation magnetization of 80 Am2/kg or more.

Abstract: A remover cover is detachably attached to an attraction head equipped at one end of a substantially rod-shaped remover. The attraction head includes a magnetic force generating surface adapted to generate a magnetic force. The cover includes a cover body shaped like a bag and adapted to cover the remover from a tip of the attraction head to at least the magnetic force generating surface, and a holding portion installed by extending from an open end of the cover body. The cover body is configured to allow itself to be turned inside out.

Abstract: A beauty tool (1) includes: a substantially rod-shaped main body (10); an attraction head (2) provided in the main body (10); and a beauty effect imparting part for imparting a beauty effect to human skin in a state where it is in contact with or close to the human skin. The attraction head (2) is provided at one end of the main body (10) and includes a magnetic force generating surface (20) for attracting and removing, by means of a magnetic force, a cosmetic agent applied to the human skin.

Abstract: A beauty instrument capable of imparting a massaging effect to skin. A beauty instrument is configured such that a pair of balls is supported at the tip of a handle. The balls are positioned at a distance from each another, and are capable of rotating around respective axes thereof.
