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.

An apparatus and method for treating a skin lesion on a user includes obtaining images of the user from a camera, determining an area of the user's body for treating the skin lesion, positioning an LED assembly comprising an LED array, and activating one or more LEDs in the LED array to treat the skin lesion.

Devices utilizing holographic 4D plenoptic capture and display technologies to generate a light field function to provide glasses-less vision correction for observers with imperfect vision, and to project an image according to the generated light field function, and methods for calibrating a four-dimensional light field for a user with an uncorrected visual acuity.

Light-based systems and methods are provided with targeted antibacterial action for mouth care in animals such as dogs. In various embodiments, the device includes a substantially impermeable shell. The shell has an outer surface. The outer surface has at least one substantially transparent region. The device further includes at least one light-emitting diode disposed within the shell. The at least one light-emitting diode is adapted to emit light having a wavelength between about 400 nm and about 1,000 nm when powered. The at least one light-emitting diode is configured to provide an average light intensity of between about 10 and about 50 mW/cm.sup.2 across the at least one substantially transparent region of the outer surface. The device further includes a power source disposed within the shell. The device further includes a switch at least partially disposed within the shell and adapted to control current flow from the power source to the at least one light-emitting diode.

Disclosed is a non-contact ultrasonic skincare device having LED light irradiation and mist spraying functions. The device includes a dome mask in a form of a hemisphere, wherein one side thereof is partially open, and an inner space is defined by the dome mask; an LED power source installed on an inner ceiling face of the dome mask so as to emit light into the inner space; an ultrasonic oscillator installed on the inner ceiling face of the dome mask so as to generate ultrasonic waves and apply the generated ultrasonic waves into the inner space; a spray nozzle installed on the inner ceiling face of the dome mask so as to spray a cosmetic stored in a storage tank into the inner space in a form of mists as fine particles; and a power supply for supplying power to each of the LED power source, the ultrasonic oscillator, and the spray nozzle; and a controller configured to control an operation of each of the LED power source, the ultrasonic oscillator, and the spray nozzle.

An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

A system and method to selectively illuminate (part of) an infant during phototherapy uses an array of collimators and a set of light sources to control impingement of electromagnetic radiation on the infant.

A therapeutic light emitting diode lighting system to treat seasonal affective disorder, to be provided at an upper portion of a hot tub basin above an indicated maximum water level, the hot tub basin defining at least one seat portion and corresponding headrest defined by the hot tub basin such that a facial region corresponds to the headrest, the facial region corresponding to a facial area of a person seated in the seat portion and supported by the headrest, the therapeutic light emitting diode lighting system including at least one array of light emitting diode (LED) bulbs provided on the upper area, the LED bulbs configured to illuminate colors and wavelengths selected to treat seasonal affective disorder, the LED bulbs being angled to direct light at the facial region of the hot tub body.
