1. An applicator for applying a product to the eyelashes and/or eyebrows, having an applicator member having:
a core extending along a longitudinal axis,
spikes that are carried by the core, have, in face-on view when viewed along the longitudinal axis of the core, a substantially triangular shape over at least 50% of their height, with a side that is oriented substantially radially, and have a cross section at the base of the spike taken perpendicularly to this side, satisfying the relationship e/L of between 0.4 and 0.6, where e denotes the thickness of the section measured in the direction of the longitudinal axis of the core and L denotes the width of the section measured in a direction perpendicular to the longitudinal axis of the core,
the substantially triangular shape of the spikes being triangular or approximately triangular, with sides that differ from those of an imaginary triangle that is most similar by a relative difference that is less than 10%, this relative difference being defined by the ratio f/d, f denoting the distance between the side of the approximate triangle which extends obliquely and that of the similar imaginary triangle which extends obliquely, and d denoting the length of the corresponding side of the similar imaginary triangle.
