RAZOR BLADES

A razor blade (1"') including a blade body (11), an expanded coating structure arranged on a surface (17) of the blade body (11) so as to cover the blade body at least partially, the expanded coating structure including one or more expanded polymer microspheres, at least one of the one or more expanded polymer microspheres including a gas encapsulated within a hollow thermoplastic polymer shell . A process for fabrication of same, including providing a blade body (11), depositing a liquid suspension, the liquid suspension including expandable polymer microspheres dispersed in a liquid uncured polymer precursor, each expandable polymer microsphere including a gas encapsulated within a hollow thermoplastic polymer shell, on a surface (17) of the blade body (11) to obtain a deposit (2), and expanding at least a portion of the expandable polymer microspheres in the deposit (2) to obtain an expanded deposit (22) including one or more expanded polymer microspheres arranged on the surface (17) of the blade body (11), the liquid uncured polymer precursor being configured to remain uncured during expansion of the expandable polymer microspheres. A skincare device including such a razor blade (1"'). A process of fabricating same, including attaching such a razor blade (1''') to a cartridge.
