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 treats skin by radiation. The device has a housing accommodating a radiation source and having an exit opening for the radiation. The device activates the radiation source only if the presence of skin immediately in front of the exit opening is detected. The radiation source cannot be activated if the exit opening is not covered.

Skin treating device comprising a protected radiation exit opening

A device for the treatment of skin by radiation pulses. The device has a detector measuring a biophysical property of skin, such as temperature increase, dispersion or absorption coefficient, or reflection coefficient for light having a predetermined wavelength, and also has a control unit which determines, from the biophysical property, a safe dose of radiation. The device automatically protects against an overdose from the radiation source. The invention can be used, not only in a hair removing device such as a laser epilator, a laser shaver or a flashlight epilator, but also in devices for the medical treatment of skin by means of radiation, such as photodermatology systems.

Skin treating device with protection against radiation pulse overdose

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.
