Abstract: In one aspect, a method of tightening skin and/or reducing scar tissue is described herein. The method comprises performing a fractional laser ablation in a treatment area of the skin, thereby removing a column of the skin and forming a columnar vacancy in the skin, the columnar vacancy having a perimeter defined by a first side and a second side opposite the first side, the first side and the second side each comprising an epidermal layer, a dermal layer, and a subcutaneous layer of skin. The first side of the columnar vacancy is contacted to the second side of the columnar vacancy, thereby closing the columnar vacancy.

Abstract: In one aspect, devices for light treatment of skin are described herein. A device described herein, in some embodiments, comprises an interior compartment having a proximal end and a distal end, and an optical aperture disposed at the distal end. The device also comprises a laser or BBL source that produces a laser or BBL beam. The laser or BBL beam has a first optical path within the interior compartment, between the proximal end and the distal end. Additionally, the first optical path exits the interior compartment through the optical aperture. The device further comprises an imaging system that receives a return signal from the aperture. The return signal received from the aperture has a second path within the interior compartment. Further, a selectively reflective optical element is disposed in the first and second optical paths. The selectively reflective optical element generally transmits the laser or BBL beam.

Abstract: In one aspect, methods of laser treatment of skin are described herein. In some embodiments, such a method comprises forming at least one fractional column or region of tissue in skin of a patient, wherein the fractional column has a structure along a z-direction orthogonal to an exterior surface of the skin, and wherein the structure of the fractional column varies along the z-direction in one or more ways. For instance, the structure of the fractional column can vary along the z-direction in one or more of the following ways: angular orientation relative to the exterior surface of the skin; ablated channel width or diameter; coagulation zone thickness; coagulation zone offset in an x-direction or a y-direction perpendicular to the z-direction; coagulation zone intensity; and thermal insult. Moreover, in some cases, the fractional column is defined by a plurality of segments that differ in a manner described above.
