1. A device for dispensing a fluid product, comprising a body, a reservoir containing one or two doses of a fluid product, the reservoir comprising a stopper that closes off the reservoir in a sealed manner before actuation, a dispensing head provided with a dispensing orifice, and actuating means for dispensing at least a portion of the fluid product through the dispensing orifice during actuation, the dispensing head receiving an insert comprising a channel that connects, during actuation, the reservoir to the dispensing orifice,
wherein:
said stopper comprises a hollow axial sleeve suitable for sliding within said reservoir during actuation, said hollow axial sleeve being closed off before actuation by a deformable radial membrane,
said insert comprises a point configured to pierce said membrane of said stopper at the time of actuation, and a piston configured to slide in a sealed manner within the reservoir during actuation, and
wherein:
said point and said piston form an integral one-piece construction with said insert,
said piston surrounds said point, and
said membrane deforms by bulging upwards when pressure in said reservoir increases during actuation.
