Esthetic apparatus useful for increasing skin rejuvenation and methods thereof

An apparatus of fractional coring for directional skin tightening, comprising:

• (i) an excisor configured to produce a plurality of excised tissue portions in a region of skin tissue;
• and
• (ii) a fastener configured to secure to the skin region a stretching/compression device, the stretching/compression device having at least two portions and adapted to provide contraction or expansion of said skin region in at least one predetermined direction, thereby promoting collagen growth and providing directional skin tightening in said skin tissue;
• wherein said excisor is in communication with at least one RF generator adapted to provide RF energy, such that said excisor is adapted to provide RF energy to said region of skin tissue;
• wherein said producing a plurality of excised tissue portions in a region of skin tissue is performed by a system comprising at least one robotic arm, said at least one robotic arm
• comprising at least one skin coring instrument;
• and
• wherein at least one skin coring instrument comprises:
• a micro-coring punch including a plurality of punches arranged in a predetermined pattern, the plurality of punches comprising at least six punches;
• a motor configured to rotate each punches of the plurality of micro-coring punches around at least one axis of symmetry of each punch and wherein rotation of each punch of the plurality of punches is synchronized with the rotation of a remainder of the plurality of punches;
• a conveyor configured to advance the micro-coring punch towards skin and to position the micro-coring punch to penetrate the skin to a depth of at least two millimeters;
• and
• a stepper configured to step a micro-coring punch and locate the micro-coring punch such that at least one element selected from a group consisting of vertex, facet and any combination thereof of a stepped micro-coring punch hexagon is overlapped with at least one element selected from a group consisting of vertex, facet and any combination thereof of a previous micro-coring punch hexagon.
