A method of enhancing penetration of a topical composition of 5-aminolevulinic acid (ALA) into tissue for photodynamic therapy includes topically applying ALA to a treatment area to be treated with photodynamic therapy. The method further includes, after the ALA is applied to the treatment area, covering the treatment area with a low density polyethylene barrier. The treatment area is covered with the low density polyethylene barrier prior to light treatment to minimize transepidermal water loss from the treatment area.

A phototherapy system for treating a user can include an applicator, a controller, and a communication cable configured to couple the applicator and the controller. The applicator can include a light source, a thermal sensor, and a fan. The controller can be in communication with the applicator. The controller can be configured to receive a predetermined treatment regimen to be applied to the user via the applicator. A method for treating skin presenting psoriasis includes providing a phototherapy system. The user can select a skin type on the controller. The use can place the applicator adjacent to the skin presenting psoriasis, eczema, or vitiligo. The user can receive a light therapy treatment from the applicator, whereby the psoriasis, eczema, or vitiligo has been treated.

Provided is a skin care device including a head part brought into contact with skin of a user, a battery configured to supply power for operation of the head part, a body part having a fastening portion provided at one end to which the head part is fastened and provided with the battery therein, and a cap assembly detachably attached to one end of the body part and forming an accommodation space configured to accommodate the head part, wherein the cap assembly includes a sterilization module disposed to irradiate ultraviolet light toward the head part when the cap assembly accommodates the head part.

Provided herein are methods and systems for modulating temporal patterns of neuronal activity in the brain. A method of the present disclosure may include using optogenetics to stimulate a one or more of thalamocortical projections, thalamic relay neurons, cortical projection neurons, cell bodies in a thalamic submedial nucleus, and cell bodies in the VLO in the brain, in conjunction with fMRI of different regions of the brain to directly visualize the global influence of the VLO's afferent and efferent connections, and characterize how different temporal patterns of activity in the VLO circuit affect brain dynamics by driving its input and output at distinct frequencies.

A device and method for disinfecting and/or enhancing healing of a wound or surgical site facilitates placing a light-emitting device with a frame having a central void, the central void adapted to surround the wound or surgical site; an illumination source disposed on the frame for directing safe, therapeutic light centrally towards the underlying wound or surgical site; and the transparent central void enabling visualization and clinical monitoring of the underlying wound or surgical site.

A method of reducing the risk of ventilator-associated pneumonia by decontaminating the oropharynx using a safe, antimicrobial light-emitting device.

Systems and methods for phototherapeutic modulation of nitric oxide in mammalian tissue include use of a first wavelength and first radiant flux of light to stimulate enzymatic generation of nitric oxide, and use of a second wavelength and second radiant flux of light to stimulate release of nitric oxide from endogenous stores of nitric oxide. Pulsed light and/or partially non-overlapping light impingement windows may be used. Non-coherent light impinged on tissue may include a peak wavelength in a range of from 410 nm to 440 nm in the absence of light emissions having a peak wavelength of from 600 nm to 900 nm.

Systems and methods are described for treatment of neurological conditions in which transcranial illumination using infrared, near-infrared and/or red wavelengths of light are delivered into the brain of a patient using a portable head wearable device. Arrays of light emitters are simultaneously controlled to provide a selected power density and distribution during a therapeutic session to treat a condition of the patient. An external controller such as a touchscreen tablet or laptop computer can be used to select illumination parameters for each patient. The system can be used to provide treatment to children such as those having autism spectrum disorder (ASD).

A device, for vision training and therapy, comprises a spectacle frame including a left rim, a right rim, and a bridge connecting the left rim and the right rim, wherein the left rim and the right rim include a plurality of therapeutic light sources located along the left rim and the right rim, for providing light therapy to the eyes of a user, a longitudinal member connected with the spectacle frame, and extending away from the spectacle frame, along the line of sight of the user, wherein the longitudinal member includes a plurality of colored light sources connected by a white stripe arranged to be viewable by both eyes of the user and a controller connected with the plurality of therapeutic light sources and the plurality of colored light sources. Further, the longitudinal member is extendible through an extension mechanism attached to the spectacle frame.

A device for eradicating at least one pathogen in a nasal passage of a human or animal may include a housing configured to be inserted into the nasal passage, at least one radiation source, configured to emit radiation, coupled to the housing such that at least a portion of a radiation emitting surface, upon insertion of the housing into the nasal passage, faces at least a portion of nasal lining of the nasal passage, and an electrical circuit carried by the housing and electrically connected to the at least one radiation source, the electrical circuit including at least one circuit component for controlling the at least one radiation source to emit the radiation to irradiate the nasal passage, the emitted radiation having a frequency or range of frequencies at which the at least one pathogen in the nasal passage, when irradiated by the emitted radiation, is eradicated.
