Abstract
The invention relates to a dermatological treatment device (1) including a laser head (2) capable of shooting a laser beam (3) towards a target region (4) of the skin (5) of a patient, a pyrometer (6) capable of measuring the temperature (T) of the skin (5) in said target region (4), a timer (7) capable of measuring the duration (D) of the laser shot, and a control means (8) capable of selectively activating or deactivating a laser shot, the control means (8) being configured to deactivate the laser shot when the duration (D) of the shot reaches a duration threshold in seconds (Sd) as determined by a linear function in the form Sd=(To−T)/C, where T is the measured temperature (T) of the skin, To is a target temperature, and C is an average heating coefficient of the skin.
