The invention relates to the field of cosmetic apparatuses, and provides a micro-current cosmetic instrument and a skin care apparatus. The micro-current cosmetic instrument comprises a switch body, amask mold, wires and a plurality of metal particles, the plurality of metal particles are separately embedded in the mask mold, one ends of the wires are connected with the switch body, and the otherends of the wires are connected with the plurality of metal particles in sequence. According to the micro-current cosmetic instrument and the skin care apparatus, the plurality of metal particles areconnected through the wires, when the metal particles and the user skin are in contact, a channel is formed, micro-current is further formed, the micro-current can promote the absorption capability of the skin, the absorption of various skin care products for the skin is improved, the functions of the skin care products can reach the optimal, the metabolism of cells can be promoted, the blood circulation is improved, and the cell aging is delayed; a certain temperature is generated by electrification of the metal particles so that the user skin is massaged, and the absorption capability of the skin is further improved; besides, the skin care apparatus can be used with the cooperation of other devices or other skin care products so that the skin care effect is better.
