    Abstract: The invention relates to a system (10) for dispensing a product, comprising a dispenser that can house at least two cartridges, each of which includes a reservoir containing a base product, a first base product comprising at least 0.1 wt.-% particles having a density differential relative to the medium containing same, preferably of at least 0.5 g/cm3, in particular particles having a density greater than or equal to 2 g/cm3, and a thickening agent. The dispenser allows at least two base products to be dispensed in adjustable proportions, the viscosity of the first base product being preferably greater than 2 Pa·s and more preferably greater than or equal to 4 Pa·s.

    Abstract: Method for shaping an applicator for applying a cosmetic composition to a predefined region of the keratin materials of a user. The applicator defining an application surface. The method using a shaping system comprising one or more movable elements and topographical data from an operation of acquiring, preferably digitally, the topography of at least a portion of said predefined region, in which method the shaping system automatically positions the one or more movable elements at least according to the topographical data, the positioning of the one or more movable elements imposing a shape to the application surface of the applicator.

    Abstract: The present invention relates to a process for colouring a base cosmetic composition, comprising the step consisting in producing, on at least one first zone and one second zone, which are different, at the surface of said composition, two printings of at least one ink originating from an inkjet printer, the base composition and the ink being such that the time needed for the complete penetration, at ambient temperature of 20° C. and under atmospheric pressure, into the base composition of an amount of 20 μl of water deposited at its surface is less than 30 s and such that the time needed for the complete penetration into the base composition of the same amount, 20 μl, of ink deposited at its surface is less than 15 s.
