1. A dispenser and replaceable cartridge system comprising a dispenser adapted to removably receive a replaceable air-less cartridge and dispense a fluid cosmetic product contained in a replaceable cartridge, the dispenser and replaceable air-less cartridge system comprising:
a depressible pump head having an opening for dispensing cosmetic product;
a pump housing adapted to support the depressible pump head and having a first connector portion configured to connect the pump housing with a replaceable air-less cartridge;
a pump engine supported by the pump housing, operable by the depressible pump head, and having defined therein a fluid path adapted to be at least partially disposed within a replaceable air-less cartridge, the fluid path allowing flow of cosmetic product contained in the replaceable air-less cartridge to the depressible pump head opening;
a retaining cover comprising a body having a pump opening adapted to receive therethrough at least a portion of the pump engine and a first fixation portion adapted to connect the retaining cover to a dispenser body;
a replaceable air-less cartridge being sealed and self-contained prior to installation in the pump housing and defining a cosmetic product reservoir, the replaceable air-less cartridge having a second connector portion adapted to matingly connect the replaceable air-less cartridge to the pump housing at the first connector portion, and having an opening through which the pump engine is at least partially received into the reservoir;
the replaceable airless cartridge further comprising:
a cover disposed over the opening and adapted to prevent spillage of fluid cosmetic product contained in the reservoir prior to installation of the replaceable air-less cartridge in a dispenser, the cover being displaceable to permit a portion of the dispenser pump to be disposed within the reservoir upon installation of the replaceable air-less cartridge in a dispenser;
a seal cover disposed over the replaceable air-less cartridge opening and configured to be removed or pierced to permit access to the fluid contained in the reservoir by the pump assembly when installed;
a piston disposed at the bottom and at least partially in the reservoir opposite the dispenser pump when the replaceable air-less cartridge is installed in a dispenser; and
a fluid cosmetic product disposed in the reservoir;

the dispenser body having an opening at one end and defining an interior configured to receive the replaceable air-less cartridge, the dispenser body having a second fixation portion adapted to connect the dispenser body with the retaining cover at the first fixation portion to enclose the body interior with the replaceable air-less cartridge contained therein;
whereby depressing the depressible pump head causes cosmetic fluid contained in the replaceable air-less cartridge reservoir to flow through the fluid path of the pump engine and through and out the opening in the pump head.
