Electrosurgical systems, apparatus, and methods for the controlled ablation, cutting, forming voids, or otherwise treating skin tissue. An electrosurgical apparatus of the invention includes a treatment assembly including a plurality of treatment units, each treatment unit having an active electrode terminal adapted for the controlled, localized ablation of skin tissue. A method of performing an autologous hair transplant procedure includes electrosurgically forming a plurality of graft sockets in a recipient region of skin tissue. Each of the plurality of graft sockets comprises a void in the skin tissue, formed by positioning a treatment unit in at least close proximity to the skin surface in the recipient region, and thereafter applying a high frequency voltage between the active electrode terminal and a return electrode. Apparatus and methods for epilating the skin are also disclosed.
