"In certain embodiments, a treatment can cause sufficient thermal injury in the dermal region of the skin to elicit a healing response to cause the skin to remodel itself. This can result in more youthful looking skin and an improvement in the appearance of cellulite. In one embodiment, sufficient thermal injury induces fibrosis of the dermal layer, fibrosis on a subcutaneous fat region, or fibrosis in or proximate to the dermal interface. In one embodiment, the treatment radiation can partially denature collagen fibers in the target region. Partially denaturing collagen in the dermis can induce and/or accelerate collagen synthesis by fibroblasts. For example, causing selective thermal injury to the dermis can activate fibroblasts, which can deposit increased amounts of extracellular matrix constituents (e.g., collagen and glycosaminoglycans) that can, at least partially, rejuvenate the skin. The thermal injury caused by the radiation can be mild and only sufficient to elicit a healing response and cause the fibroblasts to produce new collagen. Excessive denaturation of collagen in the dermis causes prolonged edema, erythema, and potentially scarring. Inducing collagen formation in the target region can change and/or improve the appearance of the skin of the target region, as well as thicken the skin, tighten the skin, improve skin laxity, and/or reduce discoloration of the skin.
