A hair-removing device () includes a laser source (), an adjustable laser beam manipulator () for positioning a laser beam () of the laser source () in a target position () on a skin () to be treated, and an image sensor () for detecting an image () of the skin. The hair-removing device further comprises a control unit () which determines a position and orientation on the skin of a hair () to be removed, and which determines the target position of the laser beam as a function of said position and orientation of the hair. The control unit brings the laser beam manipulator in a state corresponding to the target position of the laser beam, and activates the laser source when the laser beam manipulator has reached said state. Thus, the hair-removing device is suitable for use by inexperienced users, and is particularly suitable for the consumer market. In a particular embodiment, the control unit determines the target position of the laser beam in a position () on the skin under which a root () of the hair is present, so that the root of the hair is destroyed and the hair-removing device () is an epilating device by means of which the hair is removed for a relatively long time or even permanently. In another embodiment, the control unit determines the target position of the laser beam in a position () on the hair where the hair comes out of the skin, so that the hair is burnt through near the skin surface and the hair-removing device (&#x2033;) is a shaving device by means of which a high skin smoothness is obtained.

Hair-removing device with a controllable laser source

A device for the treatment of skin by radiation. The device has a housing with a radiation source, a control unit, and a detector for detecting an image of the skin. The control unit has a processor which determines from the image a dimension and color of a target object to be treated, and determines from the dimension and color a pulse dose of the radiation source necessary for treating the target object. The device may be a laser epilator used to destroy a root of a hair based on the thickness of the hair root and the color of the hair. The device can also be configured as a laser shaver, delivering a pulse dose necessary to cut a hair based on the thickness and color of the hair.
