This skin aesthetic device allows for precise adjustment of the degree to which multiple needles are inserted, ensuring sufficient skin aesthetic effects, and enables easy correction of errors in needle insertion during use. [Solution] The skin beauty device 100 has a transfer mechanism that screws onto the ball screw rotating shaft of a stepping motor (SM) and moves forward from the origin position, then moves backward to return to the origin position. The transfer mechanism moves forward by a distance corresponding to the forward signal of the SM, pushing the needle bundle, so that multiple needles fixed to the needle bundle are precisely inserted into the skin to an extent corresponding to the forward signal, and alternating current supplied via the transfer mechanism is passed through the multiple needles for a predetermined time inside the skin to promote skin regeneration by forming tiny wounds. When it senses that the transfer mechanism has moved backward by a distance corresponding to the backward signal of the SM and returned to the origin position, the transfer mechanism is moved forward again by a distance corresponding to the origin correction drive signal of the SM to correct the origin position.
