A transparent cover member for a skin treatment device passes light and heat to a user's skin. The transparent cover member presents a comfortable flat surface at its exterior, and includes features that couple to a heating element that surrounds a plurality of visible light LEDs. The transparent cover member can include retaining features to assist in assembling the head assembly of the skin treatment device.

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.

A soft thermoformable elastomer with a phase change material exhibiting high latent heat of fusion. The compound provides elasticity, softness, formability, and heat over an extended duration and to facilitate prolonged skin contact at elevated temperatures. Used in combination with active ingredients the increased temperature and formability provides enhanced transdermal delivery through the skin. Thermoplastic elastomers may be manufactured by mixing together plasticizing oil, a triblock copolymer, a paraffinic substance and one or more additives, e.g., an antioxidant, an antimicrobial agent, and/or other additives to form a mixture which melted then cooled into the thermoplastic elastomer. During cooling, the thermoplastic elastomer may be molded or otherwise formed into any number of articles including, but not limited to, prosthetic liners, prosthetic sleeves, external breast prostheses, breast enhancement bladders, masks, wound dressing sheets, wound dressing pads, socks, gloves, malleolus pads, metatarsal pads, shoe insoles, urinary catheters, vascular catheters, and balloons for medical catheters both vascular as well as urinary. Active ingredients are preferably added to the cooling thermoplastic elastomer when the temperature is below 100° F. to prevent heat degradation and/or breakdown of vital proteins.

The present invention provides a skin care device which performs optical care and thermal care in one device and minimizes noise that may occur in the skin measurement sensor, the device comprising: a housing for forming an outer appearance; a heat transfer bracket disposed at one end of the housing; a light source unit mounted on one end of the housing; a light transfer bracket including a light permeable material and fixed to the housing to cover the light source unit; a skin measurement sensor extending through a first hole formed in the light transfer bracket to protrude outward; and a first substrate mounted with the light source unit and spaced from the skin measurement sensor.

A heating patch for skin care including a substrate unit; an application electrode unit formed on the substrate unit in a predetermined pattern, and which includes a first electrode and a second electrode to which power supplied from the outside is applied; a heating unit including first and second heating electrodes, which respectively extend a predetermined length from the first and second electrodes so as to face each other at a certain length without being electrically connected, and a plurality of conductive heating materials formed to have predetermined areas in an overlapping part in which the first and second heating electrodes face each other and generate heat while allowing the first and second heating electrodes to communicate with each other during application of power; and a pair of cover members arranged on both surfaces of the substrate unit to prevent external exposure of the applied electrode unit and heating unit.

Localized heating can use a fixed-frequency planar transmission line resonators arranged along a main-line, selected by tuning an electromagnetic input signal frequency applied to the main line for depositing heat in an adjacent active substrate. More generally, adjusting input signal frequency can be used to selectively address and energize an electromagnetic-to-heat, an electromagnetic-to-vibration, or other transducer to controllably direct energy toward a desired transducer load. Resonators or other electromagnetically energized transducers can be arranged to electromagnetically interfere, such that specifying or adjusting a relative phase of applied electrical signals can be used to specify or adjust the energy directed toward a desired transducer load. Temperature sensing can characterize a material in a target region near the transducer. A cold-hot-cold temperature profile can better manage temperature and avoid overheating a dielectric material such as the active substrate material.

A modular stimulus applicator system and method are disclosed. The system includes a plurality of wirelessly controlled stimulus pods configured to be anchored to a patients body, and configured to deliver stimulus to the patients body. The stimulus can be heat, vibration, or electrical stimulus, or any combination thereof. The stimulus pods can be charged by a charging station that prevents the stimulus pods from being in contact with the patients body during charging.
