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
1-25. (canceled)
A system for producing a cosmetic effect in skin tissue, the system comprising:
- a plurality of round hollow coring needles configured to form a plurality of holes in a treatment region of the skin tissue, and
- a skin compression arrangement configured to produce and maintain a compressive stress over at least one portion of the treatment region after the plurality of holes are formed, and
- wherein at least one round hollow coring needle of the plurality of round hollow coring needles has an inner diameter between about 0.2 mm and about 0.5 mm.
The system of claim of 34, wherein the actuator handle is configured to withdraw the plurality of round hollow coring needles from the skin tissue when activated.
A system for producing a cosmetic effect in skin tissue, the system comprising:
- a handpiece, and
- a plurality of single units, each single unit including a plurality of round hollow coring needles affixed to a substrate and configured to be removably coupled to the handpiece and form a plurality of holes in a treatment region of the skin tissue, and
- wherein at least one round hollow coring needle of the plurality of round hollow coring needles has an inner diameter between about 0.2 mm and about 0.5 mm.
A system for producing a cosmetic effect in skin tissue, the system comprising:
- a handpiece, and
- a plurality of round hollow coring needles affixed to a substrate and configured to be removably coupled to the handpiece and form a plurality of holes in a treatment region of the skin tissue, and
- an actuator handle configured to move the plurality of round hole coring needles and the substrate relative to the handpiece, and
- wherein at least one round hollow coring needle of the plurality of round hollow coring needles has an inner diameter between about 0.2 mm and about 0.5 mm.
