COSMETIC PRODUCT APPLICATOR INCLUDING HELICAL FURROWS AND COSMETIC ITEM INCLUDING SUCH AN APPLICATOR

A cosmetic product applicator including a straight stick extending according to a main axis with a longitudinal direction, the stick including an external surface over which furrows are formed. Over at least one longitudinal portion of the stick, the external surface of the stick includes at least two helical furrows, one of the two furrows having a right-hand pitch and the other one having a left-hand pitch, the furrows meeting several times over the longitudinal portion of the stick, such an applicator having furrows with opposite pitches improving combing and separating of the eyelashes (or other hairs) when applying a cosmetic product. The presence of furrows having opposite pitches allows for an efficient use of the applicator both with the right hand and with the left hand, with an identical or similar make-up quality. The applicator is well-suited to be used in a "mascara pen" type mascara item.
