Definitions

  • the present invention relates to a cosmetic process for making up and/or caring for the lips, making it possible in particular to give the lips volume.
  • to give volume also known as a volumizing effect
  • a means for making the lips pouty especially for increasing the thickness of the lips and for giving them a more swollen and fleshy look.
  • the volumizing effect has mainly been obtained with the aid of makeup products of lipstick or lip gloss type, either by drawing a contour around the lips that is larger than the natural contour, or by playing with effects that consist, for example, in creating localized gloss in well-defined regions of the lips or by superposing two types of gloss, of pinpoint and diffuse type, in order to trick the eye and thus to create a sensation of volume.
  • this alternative amounts to a virtual effect, which is occasionally not perceptible to the consumer.
  • compositions with a high water-absorbing capacity Placing the composition, applied on its makeup site, in contact with water brings about an increase in its initial volume, thus generating the desired volumizing effect.
  • Such compositions are especially described in documents US 6 045 783 and EP 1 228 747.
  • Compositions with a volumizing effect using these polymers are, however, relatively unsatisfactory since the production of significant swelling requires the supply of a quite large amount of water. Furthermore, this swelling is not long-lasting and is reversible when the water evaporates.
  • the present invention is precisely directed towards satisfying this need.
  • the inventors have discovered that it is possible to satisfy the abovementioned expectations by forming a coating in the form of a set foam via the use of specific photo-crosslinkable compounds.

  • composition (M) comprising, in a physiologically acceptable medium, at least one photo-crosslinkable compound, the said compound comprising at least one activated photo-dimerizable group bearing at least one activated double bond;
  • step (ii) exposing all or part of the surface of the said coat formed in step (i) to conditions favourable for crosslinking the said photo-crosslinkable compound.
  • physiologically acceptable medium means a toxicity-free medium that is compatible with application to human keratin materials, in particular the lips.
  • lip(s) will denote all or part of the surface of one or both lips.
  • the aerated coat may be formed solely on the contour of the lips.
  • the process of the invention is a process for making up the lips.
  • anrated composition means a composition comprising a gaseous phase (for example air) in the form of bubbles. It is also known as a composition "in foam form”.
  • patent applications US 2004/126 345, WO 04/060 292 and WO 04/060 334 disclose the application, to the skin, the lips or keratin fibres such as the hair, of a composition which forms a foam after application, which will be stabilized via the film formation of a film- forming polymer.
  • the process of the invention proves to be advantageous in several respects. Firstly, it enables the user to obtain the desired volumizing effect by a single application action. As a result, the process of the invention makes it possible, quickly and easily, to produce a thick, smooth coating on the lips.
  • the coating formed at the surface of the lips according to the process of the invention may have, after a single application of aerated composition, a thickness of greater than or equal to 50 ⁇ , in particular ranging from 50 ⁇ to 5 mm and more particularly from 100 ⁇ ⁇ 2 mm.
  • the coating thus formed on the lips is stable and long-lasting, in particular for at least 4 hours and more particularly up to 12 hours. It does not collapse or break down over time. It advantageously shows good resistance to rubbing.
  • step (i) of the process of the invention may be formed according to various embodiments.
  • it is formed in situ on the lip via the application of a composition with delayed expansion.
  • the present invention is thus directed towards such a cosmetic composition with delayed expansion comprising, in a physiologically acceptable medium:
