1. A unit of a body care device for operating a skin treatment head coupled to or integrated with the unit, wherein the unit comprises:
a first connector for detachably coupling to a corresponding second connector of a housing of the body care device to provide functional coupling of the housing and the unit, wherein the functional coupling enables at least partial rotation of the unit about an axis;
a chamber with a chamber volume for hosting a material selected from the group consisting of a liquid and a semi-liquid, wherein the chamber comprises at least one first chamber opening, wherein the at least one first chamber opening comprises a check valve;
a mechanical actuator movable relative to the first connector, wherein the mechanical actuator is configured to transfer a force on the skin treatment head in a direction of the first connector onto the material to expel at least part of the material via the at least one first chamber opening out of the chamber, wherein the mechanical actuator is configurable in a plurality of positions relative to the first connector including a neutral position wherein the mechanical actuator does not transfer a force onto the material;
a channel system for providing a fluid connection between the chamber and the at least one first chamber opening; and
a first valve for controlling the fluid connection between the chamber and the at least one first chamber opening, wherein the first connector is configured to control the first valve, wherein the first valve is closed when the housing and the unit are not functionally coupled, and wherein the first valve is open when the housing and the unit are functionally coupled.
