Abstract: The present invention relates inter alia to a cosmetic method for providing skin care comprising illuminating the skin of a subject with one or more light beams, said beams together providing light to the skin having a discontinuous spectrum. The invention also relates to a method for treating a skin-related disorder and relates to a light-emitting device for use in these methods.

Abstract: An adaptation device is provided for adapting an UV-Vis cuvette to perform in-situ spectroanalytical characterization of redox processes using gas species or solutes in a controlled atmosphere, the device configured to fit the open end of a UV-Vis cuvette intended to contain products to be measured during achievement of spectroanalytical measurements. The device comprises a main body configured to form a lid covering the opened end of the cuvette, the main body having a first part and a second part; a working, a counter and a reference electrode with removable parts at the respective ends of three conductors coming from outside and passing through the main body; a gas inlet to allow introduction of a gas the gas inlet having one aperture directed to the working electrode and second aperture directed to the bottom of the cuvette, a gas outlet intended to let the reactive gas in excess to flow out of the cuvette and an solution inlet tube for titration measurements.
