Abstract
Disclosed herein are devices (e.g., needles (e.g., hollow needles), hollow staples, articles, apparatuses, and systems), kits, and methods for treating skin and skin conditions, for example, by promoting skin tightening, such as by reducing skin laxity and reducing tissue area or volume.
Claims16
An article for producing a cosmetic effect in a skin tissue, comprising:
- a first layer and a second layer;
- a plurality of hollow needles affixed between the first and second layers, wherein the article is constructed and arranged so that the needles can adopt at least two positions relative to the layers, wherein the at least two positions include a retracted position and a protracted position;
- an applicator configured to contact at least one of the plurality of needles;
- and
- a z-actuator at the applicator, whereby pressure from the applicator applied to the at least one of the plurality of needles extends the at least one of the plurality of needles to the protracted position,
- wherein the at least one of the plurality of needles is in contact with a tensioner that is configured to restore the at least one of the plurality of needles to the retracted position after the at least one of the plurality of needles are extended to the protracted position, and
- wherein at least a portion of the first layer further comprises a texture configured to reduce movement along the skin tissue.
