Cosmetic product for applying a cosmetic preparation to the skin, having - a discoid, dimensionally stable preparation in a position P, - wherein, in its centre, the preparation carries a wheel-shaped and/or disc-shaped core, that is to say a preparation carrier, - an at least two-part housing having - a first, outer housing part and a second, inner housing part of cylindrical basic structure, each having two cylinder bases, which are arranged parallel to one another and are connected via a cylinder wall, a laterally open cylinder, that is to say a cylinder segment, being formed as a result, - wherein the preparation carrier and the first and second housing parts are connected in a rotatable manner by an axis body in one or more parts, - the first, outer housing part encloses the preparation over up to at least 40% of the circumference thereof, and - the second housing part is arranged in a pivotable manner within the first housing part and can be pivoted out of the first housing part, a closed cylindrical housing, which fully encloses the preparation, being formed as a result, - the preparation has no contact with the first and second housing parts, wherein the inner housing part and the axis body or the preparation carrier each have means which can interact with one another when the inner housing part is pivoted into the open position in relation to the outer housing part, wherein the interaction results in the preparation following the rotary movement of the inner housing part, that is to say it results in forced rotation, characterized in that - the second housing part and the preparation carrier have means which connect when the second housing part is pivoted into the first housing part, and therefore the preparation carrier is carried along at least over part of the rotation of the second housing part, - and therefore, when the second housing part is pivoted into the first housing part, the discoid preparation is pivoted away from the position P by an angle A, wherein, following a number of B closing and opening operations, the preparation is located back in position P, where the number B is equal to the product of A -1 times 360°. - a discoid, dimensionally stable preparation in a position P, - wherein, in its centre, the preparation carries a wheel-shaped and/or disc-shaped core, that is to say a preparation carrier, - an at least two-part housing having - a first, outer housing part and a second, inner housing part of cylindrical basic structure, each having two cylinder bases, which are arranged parallel to one another and are connected via a cylinder wall, a laterally open cylinder, that is to say a cylinder segment, being formed as a result, - wherein the preparation carrier and the first and second housing parts are connected in a rotatable manner by an axis body in one or more parts, - the first, outer housing part encloses the preparation over up to at least 40% of the circumference thereof, and - the second housing part is arranged in a pivotable manner within the first housing part and can be pivoted out of the first housing part, a closed cylindrical housing, which fully encloses the preparation, being formed as a result, - the preparation has no contact with the first and second housing parts, - the second housing part and the preparation carrier have means which connect when the second housing part is pivoted into the first housing part, and therefore the preparation carrier is carried along at least over part of the rotation of the second housing part, - and therefore, when the second housing part is pivoted into the first housing part, the discoid preparation is pivoted away from the position P by an angle A, wherein, following a number of B closing and opening operations, the preparation is located back in position P, where the number B is equal to the product of A -1 times 360°.
