Light based skin care device with controllable fluency level

摘要

A light based skin care device (10) is provided comprising a light source (11), user interface means (12), a control unit (13) and a skin sensor (14). The light source (11) is provided for providing light doses with a certain fluency level. The user interface (12) enables a user to set the fluency level to a value between a lower limit and an upper limit. The control unit (13) is coupled to the light source (11) and the user interface means (12) for controlling the light source (11) to provide the light doses with the light intensity set by the user. The skin sensor (14) can measure a value of a physical parameter of the user's skin and is coupled to the control unit (13) for setting the lower limit and the upper limit in dependence of the measured value of the physical parameter.
