Abstract: A skin care device using an RF needle is disclosed. According to an embodiment, a skin contact part having a plurality of needles and a vacuum pressure formation unit for applying a suction force to the skin contact part are included, and thus a needle can be inserted into the skin by pulling the skin with vacuum pressure. Therefore, the skin is pulled with suction so that an equipment contact surface accurately comes into contact with the skin, and thus a needle can be correctly inserted into the inner layer of the skin.
