1. A method of skin tightening comprising:
- (i) affixing a tunable dressing to a skin region, wherein said dressing is configured, when applied to said skin region from which a plurality of incised tissue portions and/or excised tissue portions has been excised by an apparatus comprising one or more hollow needles for making incisions and/or excisions in a skin region to provide contraction or expansion of said skin region in one or more directions; and
(ii) adjusting said contraction or expansion by exposing said dressing to one or more external stimuli that result an increase in tension of said dressing, a decrease in tension of said dressing, an increase in compressive force exerted by said dressing, a decrease in compressive force exerted by said dressing, compression in one or more directions of said dressing, and/or expansion in one or more directions of said dressing,wherein said dressing comprises (i) an adhesive layer and (ii) an unstretched layer that comprises one or more materials that are naï
ve materials in that they can be stretched in subsequent use, andwherein an areal fraction of the skin region that has been excised is between 5% and 10%.
