  • the length Li of the foam 12 is less than the length Lo. Li is for example equal to approximately 18 mm, such that the ratio Li/L 0 is equal to 2/3.
  • the foam 12 is compressed. In this compressed second state, the compression allows the cells 22 of the foam 12 to close up, makes it possible to reduce the spacing between the free strands, and therefore makes it possible better to comb the fibers during the application of make-up.
  • the actuating part 16 may even, in a second position of the adjustment system 15 illustrated in figure 6, be pushed parallel to the longitudinal axis X in the direction of the arrow visible in this figure, closer to the application member 10. In that case, the tip 18 moves away from the distal end 5a of the stem.
  • the length L 2 of the foam 12 is greater than the length Lo. L 2 is for example equal to approximately 32 mm, such that the ratio L 2 /LQ is approximately equal to 6/5.
  • the foam 12 is stretched. In this stretched second state, the stretching allows the foam to be made more slender, and makes the product contained within it more accessible to the eyelashes, encouraging them to become more quickly laden with product.
  • the adjustment system can be moved both translationally and rotationally, causing simultaneous twisting and axial compression of the foam, or simultaneous twisting and axial stretching of the foam.
  • the applicator may comprise an internal helical screw thread allowing the adjustment system to be screwed in or unscrewed relative to the stem.
