Abstract

A method of applying makeup to a surface, such as the skin, the nails, hair, or the lips, is disclosed. The method includes manually depositing, using a non-magnetic cosmetic applicator, at least a first cosmetic composition in the fluid state on the surface, the first composition containing magnetic particles that are movable under the effect of a magnetic field; and manually exposing at least part of the first composition to a magnetic device producing a magnetic field, the magnetic device located above the first composition so as to orientate and/or displace at least a fraction of the magnetic particles so as to form at least one pattern according to magnetic field lines of the magnetic field without making contact with the first composition.

First claim

What is claimed is:

1. A method of applying makeup to a surface selected from the group consisting of the skin, the nails, hair, or the lips, said method comprising:
manually depositing, using a non-magnetic cosmetic applicator, at least a first cosmetic composition in the fluid state on the surface, said first composition containing magnetic particles that are movable under the effect of a magnetic field; and
manually exposing at least part of the first composition to a magnetic device producing a magnetic field, the magnetic device located above the first composition so as to orientate and/or displace at least a fraction of the magnetic particles so as to form at least one pattern according to magnetic field lines of the magnetic field without making contact with the first composition, wherein the magnetic particles within the pattern are oriented and/or displaced differently than the magnetic particles outside the pattern.

2. A method according to claim 1 , wherein said method comprises:
depositing at least said first and a second cosmetic composition in the fluid state on the surface, the first composition covering or being covered at least in part by the second.

3. A method according to claim 2 , wherein the second composition is applied to the first.

4. A method according to claim 2 , wherein the first composition is applied to the second.

5. A method according to claim 2 , wherein the second composition is colorless or colored.

6. A method according to claim 2 , wherein the second composition is transparent.

7. A method according to claim 1 , wherein the first composition comprises at least one volatile solvent.

8. A method according to claim 7 , in which the composition comprises at least one film-forming polymer.

9. A method according to claim 7 , in which the magnetic particles comprise metallic iron.

10. A method according to claim 1 , wherein the first composition comprises at least one coloring agent having optical properties that are sensitive to an external stimulus.

11. A method according to claim 10 , in which the coloring agent having optical properties that are sensitive to an external stimulus comprises at least one agent selected from the group comprising thermochromic agent, photochromic agent, tribochromic or piezochromic agent, and solvatochromic agent.

12. A method according to claim 1 , wherein the first composition comprises at least one diffractive pigment.

13. A method according to claim 1 , wherein the first composition comprises at least one absorbent coloring agent producing a color by absorbing at least a fraction of the visible spectrum.

14. A method according to claim 1 , wherein the first composition is a nail varnish.

15. A method according to claim 1 , wherein the magnetic field is exerted by a permanent magnet or by an electromagnet.

16. A method according to claim 1 , wherein the magnetic field is exerted successively on different regions of the surface that are coated with the first composition.

17. A method according to claim 1 , wherein at least one region of the surface that is coated with the first composition is not exposed to the magnetic field.

18. A method according to claim 1 , wherein the first composition is applied by means of a cosmetics applicator comprising a brush, a flocked endpiece, or a foam.

19. A method according to claim 1 , wherein the magnetic particles comprise a pigment, fibers or chains of particles.

20. A method according to claim 1 , wherein the first composition contains magnetic particles and non-magnetic particles.

21. A method according to claim 1 , wherein, after a given drying time, the first composition takes on a state that prevents the magnetic particles from changing their orientation under the effect of a magnetic field.

22. A method according to claim 1 , in which the deposited first composition is allowed to dry after application of the magnetic field.

23. A method according to claim 1 , in which the first composition is deposited on the lips or on the nails.

24. A method according to claim 9 , in which the magnetic particles comprise soft iron.
