A skin treatment apparatus (1) for treating a skin surface, comprising: a hand held base body (10); a rotor head (20), movably connected to the base body (10), and including at least one skin contacting element (22); a motor (30), operably connected to both the base body (10) and the rotor head (20) to rotatably drive the rotor head (20) relative to the base body (10) around a rotation axis (L); at least one motion sensor (40) to generate a movement signal reflecting a path of relative movement between the motion sensor and the skin surface; and a control unit (50), operably connected to the at least one motion sensor (40) and the motor (30) to control the motor (30) to rotatably drive the rotor head (20) in dependence of the movement signal of the at least one motion sensor (40).
