Abstract: A method and system in accordance with a particular embodiments of the technology includes applying a substance onto skin of a human subject. The applied substance can include a freezing point depressant and a liposome, an oil-in-water emulsion, a water-in-oil emulsion, or an oil-in-oil emulsion and can be configured to protect or target tissue. The substance and a surface of the skin can be cooled using the applicator to treat acne and other skin conditions.

Abstract: Exemplary methods and devices can be provided for harvesting a plurality of small tissue pieces, e.g., having widths less than about 1 mm or 0.5 mm, using one or more hollow needles. A fluid can be flowed through a conduit past the proximal ends of the needles to facilitate removal of the tissue pieces from the needle lumens, and can maintain the tissue pieces in a controlled and protective liquid environment. A filter can be used to extract and collect the tissue pieces from the liquid, or the tissue pieces can be deposited directly onto a porous dressing. Such tissue pieces can be used as microscopic grafts, which can be applied directly to a wound site or provided on a substrate or dressing, or stored for later use. Such microscopic grafts can promote tissue regrowth and wound healing, or can be applied to a scaffold to grow new tissue.

Abstract: A method in accordance with a particular embodiment of the present invention includes increasing a concentration of a modified or unmodified saccharide within a subject's skin, applying an applicator to the subject's skin, and cooling the subject's skin via a heat-transfer surface of the applicator. The saccharide within the subject's skin can enhance a resistance of at least some cells within the subject's skin to damage associated with the cooling. A corresponding system includes the applicator, the saccharide, and an energy-delivery device. The energy-delivery device can be configured to apply ultrasound, optical, thermal, or another type of energy to the subject's skin to drive the saccharide into the subject's skin. The system can also include a penetration enhancer configured to enhance penetration of the saccharide into the subject's skin. The penetration enhancer can be applied with the saccharide or separately.

Abstract: Provided herein are systems, compositions, and methods for improving one or more skin characteristics in a subject. These systems, compositions, and methods are configured to cool the subject's skin at a target site to a degree that alters adipocyte signaling but does not produce significant destruction of subcutaneous lipid-rich cells. In some embodiments, alteration of adipocyte signaling produces an improvement in one or more skin characteristics.

Abstract: A method and system in accordance with a particular embodiments of the technology includes applying a substance onto skin of a human subject. An applicator is then applied to the subject to cool a region of the subject. After cooling the tissue, a nucleation initiator is used to initiate a freeze event in the tissue. The nucleation initiator can be an ice crystal that inoculates the skin upon contact to create a predictable freeze event therein. The time of contact between the ice crystal and the skin can be controlled to achieve desired effects.

Abstract: Systems and methods can be implemented in which an electromagnetic charge is used to strengthen, tone, and firm muscle tissues. For example, the method may include receiving parameters for operation of a magnetic muscle stimulation device. The method may also include causing, based on the received parameters, a first alternating current having a first phase to flow through a first coil and generate a first time-varying magnetic field that induces a first electric charge in muscle tissue under a skin surface of a patient when the first applicator surface is positioned substantially on and parallel to the skin surface of the patient. The method may also include causing a second alternating current having a second phase to flow through a second coil in a similar manner. Optionally, a phase offset between the first and second phases may be adjusted to limit to a predetermined maximum electric charge.

Abstract: Systems and methods can be implemented in which an electromagnetic charge is used to strengthen, tone, and firm muscle tissues. For example, a magnetic muscle stimulation device may be provided that includes a processor and a device applicator having a housing and a coil positioned within in the housing. The processor may be configured to receive parameters for operation of the device applicator, and to cause, based on the received parameters, an alternating current to flow through the coil to generate a time-varying magnetic field that induces an integrated electric charge or electrical conductivity in a portion of tissue under a skin surface of a patient.

Abstract: A method and apparatus in accordance with a particular embodiment of the present invention includes applying adhesive onto skin of a human subject. An applicator is then brought into contact with the adhesive such the adhesive is disposed between the applicator and the subject's skin. The applicator is activated to cool a tissue region via the subject's skin, via the heat-transfer surface of the applicator, and via the adhesive. While the tissue region cools, the adhesive also cools, thereby reversibly strengthening adhesion between the subject's skin and the heat-transfer surface and forming a strong bond therebetween. The strengthened adhesion inhibits any movement of the applicator relative to the skin. After cooling the tissue region, the adhesive is warmed, thereby weakening the adhesion which allows the heat-transfer surface of the applicator to be easily separated from the skin.

A method for treating a subject's skin includes applying a hydrogel to the skin which contains the substance. The hydrogel and the skin are cooled using a cooling applicator to treat tissue via the cooling treatment by either freezing or not freezing tissue.
