Method of applying makeup to a surface and a kit for implementing such a method

Abstract

The present invention relates to a method of applying makeup to a surface, such as the skin, the nails, hair, or the lips, said method comprising the following steps: depositing at least a first cosmetic composition in the fluid state on the surface, said composition containing magnetic particles that are movable under the effect of a magnetic field; and exposing at least part of the first composition to a magnetic field, so as to orientate and/or displace at least a fraction of the magnetic particles, and so as to modify the appearance of the first composition.

1 . A method of applying makeup to a surface, such as the skin, the nails, hair, or the lips, said method comprising the following steps: 
 depositing at least a first cosmetic composition in the fluid state on the surface, said composition containing magnetic particles that are movable under the effect of a magnetic field; and    exposing at least part of the first composition to a magnetic field, so as to orientate and/or displace at least a fraction of the magnetic particles.

       3 . A method according to  claim 1 , wherein the magnetic field is applied so as to model the clarity and/or the color of at least a region of the face or of the body on which the first composition has been applied.  
   
   
       4 . A method according to  claim 1 , wherein the magnetic field is exerted by a permanent magnet.  
   
   
       5 . A method according to  claim 4 , wherein the magnet is rotated.  
   
   
       6 . A method according to  claim 1 , wherein the magnetic field is exerted by an electromagnet.  
   
   
       7 . A method according to  claim 6 , wherein the electromagnet is powered by at least one optionally-rechargeable battery.  
   
   
       8 . A method according to  claim 6 , wherein the electromagnet is switched on selectively by the user.  
   
   
       9 . A method according to  claim 1 , wherein the magnetic field is applied until the first composition obtains a fixed appearance.  
   
   
       10 . A method according to  claim 1 , wherein the magnetic field is applied for a period of time that is shorter than the period of time that causes all of the magnetic particles in the exposed region to be permanently displaced and/or oriented.  
   
   
       11 . 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.  
   
   
       12 . A method according to  claim 11 , wherein the magnetic field is exerted on regions of the surface that are disjoint.  
   
   
       13 . 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.  
   
   
       14 . A method according to  claim 1 , wherein the first composition is applied by means of a cosmetics applicator.  
   
   
       15 . A method according to  claim 14 , wherein the applicator comprises a brush, a flocked endpiece, or a foam.  
   
   
       16 . A method according to  claim 14 , wherein the applicator is non-magnetic.  
   
   
       17 . A method according to  claim 1 , wherein the magnetic particles comprise a magnetic material selected from the group constituted by: iron, nickel, cobalt, and alloys and oxides thereof, in particular Fe 3 O 4 .  
   
   
       18 . A method according to  claim 1 , wherein the first composition contains magnetic particles and non-magnetic particles.  
   
   
       19 . A method according to  claim 1 , wherein the first composition is applied to the surface through a perforated mask.  
   
   
       20 . A method according to  claim 1 , wherein the magnetic field is applied through a sheet that is permeable to the magnetic field.  
   
   
       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 kit for implementing the method as defined in  claim 1 , said kit comprising: 
 a magnetic device enabling a magnetic field to be generated; and    a cosmetic composition including magnetic particles that are movable under the effect of a magnetic field,    the magnetic device being capable of creating a magnetic field that is capable, when the keratinous material covered in a deposit of said composition is inserted in said magnetic field, of modifying the orientation and/or the position of the magnetic bodies inside the deposit.    
   
   
       23 . A kit according to  claim 22 , wherein the composition is a nail varnish.  
   
   
       24 . A kit according to  claim 22 , wherein the composition is a foundation.  
   
   
       25 . A kit according to  claim 22 , wherein the composition is a lipstick.  
   
   
       26 . A kit according to  claim 22 , wherein the magnetic particles comprise a magnetic material selected from the group constituted by: iron, nickel, cobalt, and alloys and oxides thereof, in particular Fe 3 O 4 .  
   
   
       27 . A kit according to  claim 22 , wherein the magnetic particles are aspherical.  
   
   
       28 . A kit according to  claim 22 , wherein the magnetic device comprises a magnet.  
   
   
       29 . A kit according to  claim 22 , wherein the magnetic device comprises an electromagnet.  
   
   
       30 . A kit according to  claim 1 , wherein the magnetic device includes a switch enabling the electromagnet to be powered selectively with electricity.  
   
   
       31 . A kit according to  claim 22 , wherein the magnetic device is arranged to generate a rotating field, and in particular it comprises a magnet and a motor enabling the magnet to be rotated.
