  • Patent number: 10485322
    Abstract: A cosmetic composition applicator includes an impermeable layer. An application layer of a cosmetic composition applicator absorbs the cosmetic composition, but a flexible layer may block the cosmetic composition so that the cosmetic composition is not absorbed. Thus, moisture durability may be procured, flexibility and comfortability of the applicator may be continuously procured, and since the absorption of liquid contents into the cosmetic composition applicator is suppressed, the rate of transmission to skin may be enhanced.
