|Title:||SYSTEMS AND METHODS FOR FORMING COMPLEX TREATMENT PROFILES IN SKIN|
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.
