PERSONAL CARE DEVICE

The present invention relates to a personal care device, in particular skin treatment device such as electric shaver, comprising an elongated handle for manually moving the personal care device along a body surface, a working head attached to said handle for effecting a personal care treatment to said body surface, at least one detector for detecting at least one behavioural parameter indicative of a user's behaviour when handling the personal care device, and and an adjusting mechanism for adjusting at least one working parameter of the working head in response to the detected behavioural parameter, said adjustment device including an adjustment actuator controlled by an electronic control unit provided with a control algorithm for calculating an output control signal for the adjustment actuator in response to at least one behavioural input signal indicative of the detected behavioural parameter. Said electronic control unit is provided with a modification algorithm for modifying the control algorithm on the basis of at least one modification input signal different from said behavioural input signal.
