A method for applying cannabidiol onto and into the skin is provided. The method includes applying cannabidiol onto skin and irradiating the skin and the cannabidiol with a laser light. The laser light has a wavelength ranging from 800 nm to 870 nm. The irradiating of the skin with the laser light results in at least some of the cannabidiol penetrating into the skin. The cannabidiol can be provided in a kit with a laser emitting tool.

A system configured for facilitating LLLT on a head of a user includes an LLLT system and a head-mounting device. The LLLT system includes a laser diode lead configured to output laser light suitable for LLLT and a laser controller configured to provide power to and control operation of the laser diode lead. The head-mounting device is wearable on a head of a user, and the head-mounting device comprising an attachment point. The attachment point is configured to secure the laser diode lead to direct laser light output by the laser diode lead toward a treatment area on a head of a user.

Devices and methods for impinging light on tissue to induce one or more biological effects, and more particularly enhanced testing and characterization techniques for phototherapeutic light treatments are disclosed. Such testing and characterization techniques may be particularly useful in the evaluation and development of light-based treatments for various infectious diseases, including multiple variants of SARS-CoV-2. In particular aspects, testing and characterization techniques are related to the direct testing of differentiated tissue models of human airway epithelia that have been exposed to various pathogens. Phototherapeutic light treatments and corresponding treatment protocols for light are also described that not only inactivate SARS-COV-2 variants in cell-free suspensions, but also inhibit SARS-CoV-2 infections at multiple stages of infection in tissue models of human airway epithelia in a variant-agnostic manner.

An osseointegrated fixture of a percutaneous osseointegrated prosthesis (POPs) anchors directly into a bone of a residual limb within an amputation stump. By anchoring directly into the bone, the POPs provides improved mobility, comfort, and function for an amputee, but an interface between an opening in the skin and the osseointegrated fixture, which allows the anchoring directly into the bone, is prone to infection by microbes. An anti-microbial device can be attached to and/or embedded within an extracorporeal portion of the osseointegrated fixture to irradiate at least a portion on the interface with at least one wavelength of light selected for its antimicrobial effects.

A method is presented to prevent formation of a scar or keloid following an insult to an area of a mammalian skin creating a lesion defining an outer surface, where the lesion reaches at least the dermis of the skin. The method includes irradiating the lesion with electromagnetic radiation having a wavelength between 410 nm and 430 nm for an exposure time long enough that the energy density received by the outer surface of the lesion is comprised between 15 J/cm.sup.2 and 120 J/cm.sup.2.

The present disclosure provides topical biophotonic materials and methods useful in phototherapy. In particular, the topical biophotonic materials of the present disclosure include a cohesive matrix, and at least one chromophore which can absorb and emit light from within the topical biophotonic material, wherein the topical biophotonic material is elastic. The topical bio-photonic materials and the methods of the present disclosure are useful for promoting wound healing and skin rejuvenation, as well as treating acne and various other skin disorders.

A handheld millimeter wave irradiation device including: a housing having a holding part, an irradiation part, and an operation control part; and at least one circuit board and a battery unit disposed inside the housing, the battery unit being used for supplying power to the at least one circuit board; where the holding part is used to facilitate hand holding for a user, the irradiation part is used to aim at a selected area of a human body for a millimeter wave irradiation operation, and the operation control part is used for the user to input commands to turn on/off the handheld millimeter wave irradiation device and select an operation mode of the millimeter wave irradiation operation.

Provided is a light irradiation type cosmetic apparatus including a light emitting device including: a light source that emits primary light; and a first phosphor that absorbs the primary light and converts the primary light into first wavelength-converted light having a wavelength longer than that of the primary light, wherein the light source is a solid-state light source having a rated output of 1 W or more, the primary light is light emitted from the solid-state light source, the first wavelength-converted light contains fluorescence based on an electron energy transition of Cr.sup.3+, and the first wavelength-converted light has a fluorescence spectrum having a fluorescence intensity maximum value in a wavelength range exceeding 710 nm.

A wearable optoelectronic sensing device includes a textile layer, a substrate layer, a light emitter, a plurality of light receivers, and a cover layer. The substrate layer is disposed on the textile layer. The plurality of light receivers is disposed on the surface of the substrate layer, formed as an array, and includes a first light receiver and a second light receiver. The light emitter is disposed at a geometric center of the array. A sensing wavelength of the second light receiver is greater than that of the first light receiver. A distance between the second light receiver and the light emitter is greater than a distance between the first light receiver and the light emitter. The cover layer is disposed on the substrate layer and includes a plurality of openings; the position of each corresponds to position of the light emitter and the position of each light receiver.

A bone implant includes a bore extending entirely through the bone implant. The bone implant also includes a light source to emit light onto bone adjacent the bone implant to stimulate bone growth and/or reduce bone loss.
