Abstract
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.
