Applicator

Abstract

This application relates to an applicator for applying cosmetics, skincare products, and / or medications to hairless skin. The applicator comprises a mounting portion and an application portion attached to the mounting portion, the application portion being equipped with at least two bristles. The mounting portion, application portion, and bristles are manufactured as a single piece by injection molding of thermoplastic material, the Shore hardness of which is greater than 65A. In the applicator described in this application, the mounting portion, application portion, and bristles are formed as a single piece by injection molding, thus eliminating the traditional process of hair implantation and, consequently, the risk of bristle detachment or adhesive dissolution in the cosmetic product.
