A method, a dosing device and a system for manufacturing of a lipstick mine out of at least two pasty substances are described. The method comprises inserting of a first end portion of a dosing device into a form whereby the first end portion of the dosing device comprises at least one outlet nozzle, filling of the first end portion of the dosing device with a first pasty substance, increasing of the gas pressure in the first end portion of the dosing device whereby the first pasty substance through the pressure is pressed out of the at least one outlet nozzle, removing the first end portion of the dosing device out of the form and filling up the form with a second pasty substance.
