Personal care device

A personal care device comprising a working head attached to a handle for moving the working head along a skin surface, said working head including at least one working tool defining a skin contact contour of the working head, wherein said at least one working tool is moveable relative to said handle via a support structure to allow for pivoting of the working head relative to the handle, wherein a biasing device is provided for biasing and for increasing pivotal movement resistance of said working head relative to the handle, wherein an adjustment device including an adjustment actuator is provided to adjust the biasing device to adjust a pivoting stiffness of at least part of the working head relative to the handle, wherein the adjustment actuator is controlled by an electronic control unit to adjust the pivoting stiffness of the at least part of the working head in response to at least one characteristic treatment parameter detected by at least one detector during handling of the personal care device when effecting a personal care treatment, wherein said at least one detector includes a skin contact pressure sensor for detecting a skin contact pressure of the working head against the skin surface, wherein the control unit is configured to control the adjustment actuator in response to a signal of said skin contact pressure sensor indicative of the skin contact pressure of the working head against the skin surface, wherein the control unit is configured to actuate the adjustment actuator such that the pivoting stiffness of the at least part of the working head is increased in response to the signal of the skin contact pressure sensor indicating that the skin contact pressure is increasing, and the pivoting stiffness of the at least part of the working head is decreased in response to the signal of the skin contact pressure sensor indicating that the skin contact pressure is decreasing.
