  • the ratio of the heights m / n is preferably between 0.1 and 0.9, where m is the height of the small tooth and n is the height of the large tooth.

  • Each even rank tooth of the first alignment 50a is preferably of the same height h as the adjacent odd-rank tooth of the second alignment 50b.

  • the applicator member may be vibrating, that is to say that it may be applied vibration during application, combing or removal of the product.
  • the applicator member may be rotatable, that is to say it may be rotated about the longitudinal axis of the core, for example during application, combing eyelashes or taking the product.
  • the application member is heated, that is to say it may comprise a heating element for heating the eyelashes or eyebrows, and / or the teeth and / or the soul of the implementing body.
  • the applicator member may also be vibrating and / or rotating and / or heating.
  • the teeth can be flocked and thus have a roughness or can receive a chemical or mechanical treatment promoting the sliding of the eyelashes or eyebrows.
