1 . A assembly for dispensing a cosmetic product, the assembly comprising:
 at least one disposable capsule comprising a casing containing the cosmetic product, the casing comprising a first part forming a cavity and a second part to be pierced containing the cavity; and   a dispenser comprising a housing to receive the capsule, a hollow needle with a tip having a suction opening, a suction device and a dispensing circuit coupled to the hollow needle, and a drive for driving the hollow needle between a position in which the capsule is not pierced and a position of suction of the cosmetic product,   wherein the casing has a recess projecting onto the outside of the first part of the casing, the recess defining a zone for collecting the cosmetic product,   the dispenser comprises a positioning element to position the capsule in a receiving position inside the housing so that the collection zone forms a low point of the cavity,   in the suction position of the hollow needle, the tip is located in the collection zone,   the drive is configured to drive the needle from top to bottom and vice-versa between the position in which the capsule is not pierced and the suction position, passing through the second part to be pierced of the capsule in the receiving position thereof inside the housing.   
     
     
         2 . The assembly according to  claim 1 , wherein the first part of the casing is formed by a shell, and the second part ( 12 ) to be pierced of the casing is formed by a cap ( 120 ). 
     
     
         3 . The assembly according to  claim 1  wherein, in the suction position of the hollow needle, the suction opening presented by the tip extends in height in the recess, and the tip of the hollow needle forms a space for the cosmetic product to pass between the tip and the casing of the capsule. 
     
     
         4 . The assembly according to  claim 1 , wherein the positioning element comprises guide runners complementary to a shape of the casing. 
     
     
         5 . The assembly according to  claim 4 , wherein the dispenser comprises a passage for inserting the capsule in the housing, the insertion passage being delimited by a wall having the guide runners, the insertion passage narrowing from an entrance of the insertion as far as the housing. 
     
     
         6 . The assembly according to  claim 1 , wherein the casing has a shape at least partially asymmetric along a vertical central plane parallel to an axis of insertion of the capsule in the housing. 
     
     
         7 . The assembly according to  claim 1 , wherein the capsule has an essentially flattened shape, the first part of the casing having a plane portion, 
       and wherein the dispenser comprises a heater for heating the cosmetic product and comprising a heating member in the immediate vicinity of the housing, the heating member being positioned so as to be in contact with the plane portion of the casing when the capsule is received in the housing. 
     
     
         8 . The assembly according to  claim 7 , wherein in a view from below of the capsule received in the housing, the recess is off-centre and the plane portion is centred on the casing, the plane portion being inclined in the direction of the recess. 
     
     
         9 . A cosmetic product dispenser, the dispenser comprising:
 a housing to receive a capsule containing a cosmetic product;   a hollow needle with a tip having a suction opening;   a suction device and a dispensing circuit both coupled to the hollow needle;   a drive for driving the hollow needle between a position in which the capsule is not pierced and a position of suction of the cosmetic product, the capsule comprising a casing containing the cosmetic product, the casing comprising a first part forming a cavity and a second part to be pierced enclosing the cavity; and   a positioning element, which is configured to position the capsule in a receiving position inside the housing wherein the second part to be pierced is oriented upwards, the drive being designed to drive the needle from top to bottom and vice-versa between the position in which the capsule is not pierced and the suction position.   
     
     
         10 . A disposable capsule, the capsule comprising
 a casing containing the cosmetic product, the casing comprising a first part forming a cavity and a second part to be pierced enclosing the cavity, the second part to be pierced being formed by a cap and being the only part designed to be pierced when the cosmetic product is extracted, the first part of casing being formed by a shell, the shell comprising:   a peripheral rim;   a floor;   a wall extending over a height from the peripheral rim as far as the floor;   wherein the floor comprises a flat portion and a recess, the recess projecting onto the outside of the floor of the shell of the casing, the recess defining a zone for collecting the cosmetic product, in a suction position wherein the connection zone forms a low point of the cavity, the plane portion being inclined in the direction of the recess.
