Disclosed herein is a device for skin treatment, which precisely transmits high-frequency energy to a target portion of skin tissue without causing a burn on the outer layer of the skin, thus artificially damaging the portion and inducing a wound curing reaction, therefore leading to the regeneration of skin and the propagation of collagen. The device prevents the surface of skin from suffering an injury during insertion, alleviates pain, and keeps the depth to which the needle is inserted into the skin uniform. The device includes a plurality of needles coated with an insulator except for sharp ends. A needle holding unit holds the needles. A drive unit directly or indirectly transmits a force to the needle holding unit, thus allowing the needles to be inserted into the skin. An electromagnetic wave transmitting unit is electrically connected to the needles and transmits electromagnetic waves to the needles.
