Abstract

A cosmetic treatment method. The method includes creating, on a region of the keratin materials to be treated, a set of adhesive areas and of non-adhesive areas extending between the adhesive areas. The method includes electrostatically projecting fibres onto the region.

First claim

The invention claimed is:

1. Cosmetic treatment method comprising:
creating, on a region of the skin to be treated, a set of adhesive areas and a set of non-adhesive areas extending between the adhesive areas,
the adhesive areas being formed by deposition of an adhesive composition on said region of the skin,
the adhesive areas not being connected, with two adjacent adhesive areas separated from one another by a distance ranging from 30 microns to 3 mm,
subsequent to creating the set of adhesive areas, electrostatically projecting fibres onto said region.

2. Method according to claim 1 , the adhesive areas being in the form of a network of points, each point having a diameter from 30 microns to 3 mm.

3. Method according to claim 2 , the shape of each point being circular.

4. Method according to claim 3 , the network being irregular.

5. Method according to claim 2 , the network being irregular.

6. Method according to claim 1 , the adhesive areas being formed with the aid of an adhesive applicator arranged to deposit the adhesive on the region of the skin at locations separated from one another.

7. Method according to claim 6 , the adhesive applicator transferring the adhesive by stamping.

8. Method according to claim 1 , the adhesive being applied with the aid of a stencil.

9. Method according to claim 1 , the adhesive being applied by spraying.

10. Method according to claim 1 , the adhesive being applied by bonding one or more adhesive articles to the region of the skin.

11. Method according to claim 1 , the density of the adhesive areas being from 4 to 700 adhesive areas per cm 2 .

12. Method according to claim 1 , the adhesive being chosen with an adhesive strength such that a fibre bonded to the region of the skin by means of the adhesive in one of said areas withstands a detachment force of 15 m N.

13. Method according to claim 1 , the adhesive being a pressure-sensitive adhesive.

14. Method according to claim 1 , the fibres being synthetic.

15. Method according to claim 1 , a treated person being brought to a non-zero potential during the electrostatic projection of the fibres, the non-zero potential being a potential greater than 1000 V.
