Abstract: An edge-lit device for providing light-based dermatological treatment is provided. The device may include a panel having internally reflective properties for reflecting light, the panel defining a front surface, a rear surface, a perimeter, and one or more edges extending along one or more portions of the perimeter. A rear reflector may be disposed adjacent the rear surface. The device may include one or more light emitting diodes (LEDs) positioned along at least one of the panel edges and configured to emit light into the panel such that at least a portion of the LED-emitted light reflects off the rear reflector and projects out of the panel through the panel front surface.

Abstract: Disclosed is an apparatus and method which employs an energy source, one or more switches, electronic control circuitry, and a surface that can be placed in contact with a region of a person's skin containing a benign pigmented lesion. Within the apparatus, electrical current is passed through a heating element that is thermally coupled to the surface so that this surface is heated rapidly and then is subsequently cooled rapidly. By judicious choice of the rate of heating, maximum temperatures achieved, and rate of cooling, thermal injury to the skin can be confined primarily to the epidermal region of the skin in contact with the surface.

Abstract: Apparatus and methods are provided to control a device, such as a light emitting dermatologic or cosmetic treatment device, and ensure that the device is in contact with skin while also determining the pigmentation level of skin. One or more light sources contact the skin and one or more detectors measure spectral remission from the skin. The obtained remission measurements are compared with known skin spectral remission values, and calibration allows measurements of absolute remission to be converted to fractional remission values. Skin pigmentation levels are compared to known base-line levels to determine and control appropriate treatment parameters. A temperature sensor allows correction for temperature variations. The apparatus may or may not be incorporated into the treatment device.
