Patent ID: 11331116

Abstract:
Exemplary embodiments of method and apparatus are provided for resurfacing of skin that includes formation of a plurality of small holes, e.g., having widths less than about 1 mm or 0.5 mm. For example, such small holes can be produced using a mechanical apparatus that includes one or more abrading elements provided at the end of one or more rotating shafts, thus avoiding generation of thermal damage as occurs with conventional laser resurfacing procedures and devices. The holes thus formed can be well-tolerated by the skin, and may exhibit shorter healing times and less swelling than conventional resurfacing procedures. The fractional surface coverage of the holes can be between about 0.1 and 0.7, or between about 0.2 and 0.5. The method and apparatus can produce cosmetic improvements in the skin appearance by eliciting a healing response.
