Abstract
Exemplary methods and systems can be provided for resurfacing of skin that include formation of a plurality of small holes, e.g., having widths greater than about 0.2 mm and less than about 0.7 mm or 0.5 mm, using a mechanical apparatus. Compressive and/or tensile forces can then be applied to the treated region of skin as the damage heals to facilitate hole closure, and provide enhanced and/or directional shrinkage of the treated skin area.
Claims21
A cosmetic method for producing an effect in skin, tissue, comprising:
- forming a plurality of holes in a region of the skin tissue using at least one coring needle;
- and
- providing a stress that is at least one of a compressive stress or a tensile stress in the region of skin tissue after forming the holes,
- wherein a diameter of the holes is between 0.2 mm and 0.7 mm,
- wherein the holes extend from the skin surface into the dermal layer of the skin, wherein the holes extend over an areal fraction of a surface of the region that is between 5% and 50%,
- wherein the stress provides a force in the region, along a direction that is parallel, to the surface of the region, and
- wherein the stress is maintained on the surface of the region until the holes have closed.
