Abstract
Abstract The present invention relates to a device for treating of superficial afflictions of the type telangiectasis by means of a directed light beam. The device can be produced at a very low cost compared with known devices due to the fact that a source of light (2) that produces non-coherent light is used, that means due to a non-use of laser.
