Systems and methods that enable delivery of radiofrequency energy and cryotherapy applications to adipose tissue for reduction and contouring of body fat are described herein. Aspects of the disclosure are directed to methods for reducing surface irregularities in a surface of a subject's skin resulting from an uneven distribution of adipose tissue in the subcutaneous layer. The method can include delivering capacitively coupled or conductively coupled radiofrequency energy to a target region of the subject at a frequency which selectively heats fibrous septae in a subcutaneous layer of the target region to a maximum temperature less than a fibrous septae denaturation temperature. Furthermore, the method can include removing heat such that lipid-rich lobules in the subcutaneous layer are affected while non-lipid-rich cells and lipid-rich regions adjacent to the fibrous septae are not substantially affected.
1. A method for reducing cellulite, the method comprising: transcutaneously delivering energy to a target region of a subject such that fibrous septae in a subcutaneous layer of the target region is selectively heated; andnon-invasively cooling the surface of the subject's skin such that subcutaneou
1. A method for reducing cellulite, the method comprising: transcutaneously delivering energy to a target region of a subject such that fibrous septae in a subcutaneous layer of the target region is selectively heated; andnon-invasively cooling the surface of the subject's skin such that subcutaneous lipid-rich lobules, which protrude into the subject's dermal layer to create an appearance of cellulite at the target region, are reduced in number and/or size to an extent while subcutaneous non-lipid-rich cells and lipid-rich regions adjacent to the heated fibrous septae and protected by the delivered energy are not reduced in number or size to the extent, thereby reducing surface irregularities in the surface of skin of the subject for reducing the appearance of cellulite. 2. The method of claim 1 wherein non-invasively cooling the surface of the subject's skin includes cooling the lipid-rich lobules to a temperature below 10° C. 3. The method of claim 1 wherein transcutaneously delivering the energy to the target region includes delivering radiofrequency energy, optical energy, acoustic energy, infrared energy, and/or microwaves to the target region. 4. The method of claim 1 wherein transcutaneously delivering the energy to the target region includes delivering radiofrequency (RF) energy at a frequency which selectively heats the fibrous septae. 5. The method of claim 4 wherein transcutaneously delivering the RF energy is accomplished such that a total duration of a period of delivery of the RF energy is between either about 1 minute and about 2 hours, about 1 minute and about 1 hour, about 1 minute and about 50 minutes, about 1 minute and about 40 minutes, or about 1 minute and about 20 minutes. 6. The method of claim 1, wherein non-invasively cooling the surface of the subject's skin includes cooling the target region using a treatment device that is in thermal communication with the skin and in communication with a controller, andtranscutaneously delivering the energy includes delivering the energy using the treatment device being controlled by the controller. 7. The method of claim 1 wherein non-invasively cooling the surface of the subject's skin includes cooling subcutaneous cells of the targeted tissue to a temperature below 10° C., andtranscutaneously delivering the energy includes transdermally delivering the energy to subcutaneous cells of non-targeted tissue. 8. The method of claim 1 wherein transcutaneously delivering the energy includes transdermally delivering the energy to inhibit thermal damage to subcutaneous lipid-rich cells while heat is removed from the target region. 9. The method of claim 1 wherein non-invasively cooling the surface of the subject's skin includes cooling the target region such that the subject's skin is flattened. 10. The method of claim 1 wherein non-invasively cooling the surface of the subject's skin includes applying cooling temperatures to the skin in a range from about −20° C. to about 10° C. 11. The method of claim 1, further comprising localizing cooling in the lipid-rich lobules via the transcutaneous delivery of the energy such that tissue of the fibrous septae is kept warm enough to inhibit thermal injury to the fibrous septae during the removal of the heat. 12. The method of claim 1, wherein transcutaneously delivering the energy includes periodically delivering the energy to non-targeted tissue while removing the heat from targeted tissue. 13. The method of claim 1, wherein transcutaneously delivering the energy to the target region includes delivering a sufficient amount of the energy to inhibit thermal damage to non-targeted tissue during cooling of the subject's skin.
