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 cryogenic device with a housing having a cryogen pathway for conducting a cryogen from a cryogen cartridge toward a needle probe, wherein the cryogen is configured to deliver cryotherapy to a target tissue via the one or more needles; an auxiliary pathway coupled to the cryogen pathway and exposed to a relatively low-pressure environment; and a movable sealing element configured to seal the cryogen pathway from the auxiliary pathway when the movable sealing element is in a closed position, and further configured to open the cryogen pathway to the auxiliary pathway so as to vent an amount of the cryogen to the relatively low-pressure environment when the movable sealing element is in an open position, wherein the movable sealing element is configured to be moved by a user-actuatable element coupled to the movable sealing element and separately configured to be moved by an automatic pressure relief mechanism.

Disclosed is a thermal contact sensor for use in aesthetic skin by heat treatment for altering the aesthetic appearance of a subject. The thermal contact sensor measures the difference in sensor temperature when in contact or absence of contact with the skin and automatically operates a source of optical radiation to heat the skin.

A wound or incision closure apparatus comprises a first and second panel. Each of the panels comprises a bottom adhesive layer, a medial substrate layer, and an upper load distribution layer which connect the two panels. A sensory or therapeutic element is disposed adjacent, within, or between two or more of the layers. The sensory or therapeutic element can provide sensing and/or therapy for the incision and/or monitor the incision so that the therapy can be customized and updated.

Disclosed is a temperature providing device including a housing body, a plurality of temperature transmitters transmitting different temperatures to an outside of the housing body, and a temperature adjusting unit adjusting a temperature of each of the plurality of temperature transmitters.

A method for using beauty instrument with mask includes steps of: providing a beauty instrument with mask; applying the flexible mask of the beauty instrument with mask on a user's face; and turning on the controller and selecting a function button from the plurality of function buttons on the controller, inputting a current to the at least one heating layer in the flexible mask, and heating the at least one heating layer. The beauty instrument with mask includes a flexible mask and a controller. The controller is electrically coupled with the flexible mask.

A head assembly for a skin treatment device includes a cover member for a skin treatment device passes light and heat to a user's skin. The 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 cover member can include retaining features to assist in assembling the head assembly of the skin treatment device.

A dressing system for cooling skin or a wound site on a subject comprises a dressing having a reservoir for holding a liquid. The dressing may be configured for placement proximate to a postoperative surgical wound site of the subject or on the facial area of the subject. The dressing system includes a cooling chamber external to the dressing configured to cool the liquid. The dressing system includes a pump configured to circulate the liquid between the cooling chamber and the reservoir. The dressing system may include a suction element for applying suction at, or proximate to, the dressing for removing sweat or wound drainage.

Systems and methods for generating user-specific recommendations of products or services by collaborative filtering executed and/or performed by one or more trained or untrained predictive models configured to ingest product attribute(s), product purpose(s), user location data, and/or user demographics. The predictive model(s) are leveraged to detect and determine user-specific preferences for, and preferences against, particular attributes, features, ingredients, aesthetic styles, and so on.
