Abstract
Disclosed herein are methods, apparatuses, and devices for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, or skin repositioning. Such methods and devices include an ablative apparatus, a removal apparatus, and/or a positioning apparatus.
Claims18
A method for treating skin comprising:
- lifting an epidermal and a dermal layer of skin away from underlying tissue prior to microcoring;
- excising, by the microcoring with a device comprising at least one hollow needle, a plurality of microcores from a treatment region on a skin surface of a human subject,
- the device configured to actuate the at least one hollow needle with a single actuation time of no more than 100 ms;
- the at least one hollow needle having a gauge of 21G or 22G;
- the treatment region having a length of about 10 mm and a width of about 10 mm;
- and
- removing an areal fraction of tissue of between 5% and 10% of the treatment region.
