  • Patent number: 12089679
    Abstract: A cosmetic treatment method. The method includes applying an adhesive composition to human keratin materials, especially the skin. The method includes bringing fibres borne by an applicator into contact with the adhesive composition present on the keratin materials. The method includes moving the applicator away from the skin, so as to release fibres which adhere to the keratin materials, the holding force for holding the fibres on the applicator being lower than the adhesive force for adhesion of the fibres to the adhesive composition present on the keratin materials.
