1. A device removably connectable to an apparatus with a rotational driving element, the device comprising:
a connector element configured to be detachably attached to the apparatus;
a receiving element configured to functionally couple to the rotational driving element, enabling the receiving element to rotate around an axis of rotation in response to mechanical energy transferred from the apparatus;
a base configured to connect to a skin treatment element,
a rotational coupling mechanism configured to rotationally couple the base with the receiving element; and
an oscillation generator comprising a first permanent magnet and a second permanent magnet, and configured to introduce an oscillation movement to the base in an axial direction, parallel to the axis of rotation during rotation of the base with a base rotation frequency, based on a periodical repulsion or attraction of the first permanent magnet and the second permanent induced by rotation of the receiving element,
wherein the first permanent magnet is arranged at a first circular plane and the second permanent magnet is arranged at a second circular plane offset from the first circular plane in the axial direction, such that the first permanent magnet is entirely offset from the second permanent magnet in the axial direction.
