Abstract
The invention relates to a device () for treating human skin by means of radiation. The device comprises a housing () with a radiation exit opening (). A radiation source () is accommodated in the housing. Radiation generated by the radiation source propagates from the radiation source towards the radiation exit opening via a radiation path () comprising a radiation filter having a predetermined transmission spectrum. According to the invention the radiation filter comprises a reflecting surface () via which the radiation propagating along the radiation path () is reflected. The reflecting surface has a coating which provides the reflecting surface with a reflection spectrum substantially matching the predetermined transmission spectrum. An advantage is that the reflection surface can be optimally and uniformly cooled, so that the heat generated as a result of the absorption of part of the radiation by the radiation filter can be effectively transmitted to a cooling system () of the device (). In a particular embodiment the device () is an epilator for removing hairs from the human skin and the radiation source () is a flash lamp. The radiation path () is enclosed by a channel () having a bend () and having an inner wall () on which the reflecting surface () is provided.
