in which method the shaping system (10) automatically positions the one or more movable elements (11) at least on the basis of the topographical data, the positioning of the one or more movable elements (11) imposing a deformation to the application surface of the applicator.
2. Method according to Claim 1, wherein the shaping system (10) subjects a deformable portion (21) of the applicator, in particular a membrane, to a deformation imposed by the one or more movable elements (11) according to the position taken by said elements on the basis of the topographical data, the shape of the application surface being imposed by that of the deformable portion (21).
3. Method according to Claim 1, wherein the shaping system (10) imposes a position to one or more of the movable elements (22) of the applicator, bearing a deformable portion (21), in particular a membrane, according to the positioning of the one or more movable elements (11) of the shaping system (10) on the basis of the topographical data, the deformable portion (21) undergoing a deformation imposed by the one or more movable elements (22) of the applicator, the shape of the application surface being imposed by that of the deformable portion.
4. Method according to any one of the preceding claims, wherein the shaping system (10) calculates the shape to be given to the application surface of the applicator on the basis of said topographical data.
5. Method according to any one of the preceding claims, wherein the shape imposed to the application surface (21) of the applicator corresponds to the inverse of the shape of the predefined region (P) that is intended to receive the composition (C).
6. Method according to any one of Claims 1 to 4, wherein the shape imposed to the application surface is determined on the basis of said topographical data to which at least one transformation has been applied, in particular a translation or a homothety.
7. Method according to any one of the preceding claims, wherein, on the basis of the operation of determining a shape to be imposed to the application surface, the calculation of a symmetrical shape is carried out and applied by the shaping system (10), in particular for the application of the cosmetic composition (C) to the eyelids.
8. Method according to any one of the preceding claims, using topographical data from a 3D scan of at least a portion of said predefined region (P) of the keratin materials of the user, the scan being performed in particular by one or more cameras (16) and/or by projecting structured light onto said region.
9. Method according to any one of the preceding claims, the step of shaping the applicator (20) being preceded by a step of collecting a cosmetic composition (C) that takes the form in particular of a transferable print or of a layer of powder, containing in particular pigments.
10. Method according to any one of the preceding claims, wherein the shaping of the applicator (20) is followed by a step of locking the shape of the applicator (20) and/or of the shaping system (10).
11. Method according to the preceding claim, the locking step being performed by pouring an adhesive material (26) between the movable elements (22) of the applicator (20) and/or those of the shaping system (10).
12. Method according to Claim 10, the applicator (20) including movable elements (22) provided with teeth (220), the locking step being performed by positioning one or more movable bolts (25) in the teeth (220) of the movable elements (22) of the applicator (20).
13. Method according to the preceding claim, wherein the shape given to the applicator (20) is reconfigured by removing the one or more movable bolts (25) from the teeth (220).
14. Method according to any one of the preceding claims, wherein a shape is imposed to a first device (20') by positioning the one or more movable elements (11) of the shaping system (10) at least on the basis of the topographical data, and wherein this first device (20') is used to shape an applicator (20) by positioning it on top, the applicator (20) including in particular one or more movable elements (22) bearing a deformable portion (21) that defines an application surface.
15. Method according to any one of the preceding claims, wherein the shaping system (10) is used by using the topographical data as the basis for forming a mould.
16. Method according to the preceding claim, the mould being used as an applicator for a cosmetic composition (C).
17. Method according to Claim 15, the mould being used to impose its shape to the application surface of the applicator.
18. Method for the cosmetic treatment of a predefined region (P) of the keratin materials of a user, in particular for applying make-up to same, including the application of a cosmetic composition (C) to said predefined region using the application surface of an applicator (20) shaped by means of the method according to any one of Claims 1 to 17.
19. Device for shaping an applicator for applying a cosmetic composition (C), in particular make-up, to a predefined region (P) of the keratin materials of a user, the applicator (20) defining an application surface, the device including a system (10) for shaping the applicator that comprises one or more movable elements (11),
the shaping system (10) being configured to automatically position the one or more movable elements (11) at least on the basis of the topographical data from a prior operation of acquiring, preferably digitally, the topography of at least a portion of said predefined region (P), the shape of the application surface of the applicator (20) being dependent of a deformation of the latter imposed by the positioning of the one or more movable elements (11).
20. Device according to the preceding claim, wherein the one or more movable elements (11) of the shaping system (10) include movable mechanical connections, such as actuating rods, that link a deformable portion (21), which may be used to impose the shape of the application surface, to one or more actuators (12), in particular electric, hydraulic or pneumatic actuators.
21. Device according to Claim 19 or 20, the shaping system (10) including between 0.5 and 25 movable elements (11) per square centimetre of surface.
