1. A brush for applying a cosmetic or a care product, the brush comprises:
an applying member elongated along a longitudinal axis;
wherein a proximal portion of the applying member includes a support head and a distal portion of the applying member includes a plurality of bristles;
wherein the plurality of bristles extends from a distal end face of the support head along the longitudinal axis of the applying member;
wherein the support head further includes a front face, a back face, a right face, a left face, and the distal end face;
wherein the front face is opposing the back face, and the left face is opposing the right face;
wherein the front face of the support head has a length less than a length of the back face of the support head;
wherein the distal end face of the support head comprises a first distal end face and a second distal end face;
wherein the first distal end face and the second distal end face are substantially flat surfaces and are disposed in different planes from one another;
wherein the first distal end face and the second distal end face intersect each other to form a ridge on the distal end face at their intersection;
wherein the ridge on the distal end face extends along an axis perpendicular to a longitudinal axis of the support head;
wherein the plurality of bristles on the distal end face includes bristles of different lengths including bristles of short length and bristles of long length; wherein the first distal end face supports the bristles of short length, and the second distal end face supports the bristles of long length; and wherein the length of the bristles on the second distal end face decreases gradually towards the ridge and increases on moving away from the ridge;
wherein the first distal end face and the second distal end face intersect at an angle of between 100-120 degrees;
wherein an inclination angle of the first distal end face with respect to the longitudinal axis of the applying member is in a range between 100 to 110 degrees; and
wherein an inclination angle of the second distal end face with respect to the longitudinal axis of the applying member in a range from 130 to 150 degrees.
