Un dispositivo (80) para la eliminación temporal de vello, que comprende: una unidad (10) de emisión de luz que comprende un sustrato (100) y una pluralidad de dados (101) de LED montados sobre el sustrato (100) en un área de al menos 0,2 cm2, en particular de al menos 1,0 cm2, donde al menos una primera subpluralidad de primeros dados (102) de LED de la pluralidad de dados (101) de LED se dispone para emitir luz a una primera longitud de onda de emisión pico y al menos un segundo dado (103) de LED de la pluralidad de dados (101) de LED se dispone para emitir luz a una segunda longitud de onda de emisión pico diferente a la primera longitud de onda de emisión pico, en donde el dispositivo (80) para la eliminación temporal de vello se dispone para emitir un pulso de luz de tratamiento que tiene una duración de pulso en el intervalo de entre 80 ms y 120 ms, y al menos la primera subpluralidad de primeros dados de LED tiene un flujo radiante de tal manera que se logra una fluencia radiante sobre la piel de un usuario de al menos 4 J/cm2 y menor de 8 J/cm2 mediante la aplicación del pulso de luz de tratamiento. The present invention is concerned with a skin treatment device, in particular a temporal hair removal device, having a light emission unit having a substrate and a plurality of LED dies mounted on the substrate on an area of at least 0.2 cm 2 , in particular of at least 1.0 cm 2 , where at least a first sub-plurality of first LED dies of the plurality of LED dies is arranged for emitting light at a first peak emission wavelength and at least a second LED die of the plurality of LED dies is arranged for emitting light at a second peak emission wavelength different to the first peak emission wavelength, wherein the skin treatment device is arranged to emit a treatment light pulse having a pulse length of between 10 ms and 300 ms, in particular of between 20 ms and 200 ms, optionally in the range of between 80 ms and 120 ms, and at least the first sub-plurality of first LED dies has a radiant flux such that a radiant fluence on the skin of a user of at least 1 J/cm 2 , in particular of at least 2 J/cm 2 , and optionally of at least 4 J/cm 2 and below 8 J/cm 2 is achieved by application of the treatment light pulse.
