Abstract
A cosmetic product, such as lipstick, is provided with a surface layer having a wetting angle less than the normal wetting angle of the cosmetic product. The surface layer, which can be formed by subjecting the cosmetic product to a plasma treatment process, allows a material having an ultra-glossy finish and having poor adhesion with objects which have a wetting angle in the neighborhood of the normal wetting angle of the cosmetic product to be adhered to the surface layer and hence to the cosmetic product.
