A personal care device has an electrically powered driving unit for driving a working implement of the personal care device at a desired speed and/or amplitude and/or frequency, and a control unit for controlling the driving unit in response to load onto the working implement to change speed and/or amplitude and/or frequency of the working implement upon a change in load applied thereto. The control unit includes a detector for detecting changes of an operating parameter of the driving unit, which operating value is responsive to load onto the working implement, and a powering unit for varying the electrical powering of the driving unit in response to a detected value of the operating parameter such that speed and/or amplitude and/or frequency of the working implement is changed from an idling value to an increased operation value.
