  • Patent number: 11052034
    Abstract: A subject of the present invention is to provide a cosmetic for unevenness correction which has an excellent effect of concealing wrinkles and pores and correcting skin unevenness and has good compatibility with a makeup cosmetic. The present inventors have found that the cosmetic for unevenness correction which conceals wrinkles and pores and has good compatibility with a makeup cosmetic at the time of application can be easily provided by using a polyacrylate water-absorbing polymer having a specific water absorption capacity, but not a water-soluble macromolecule having a thickening effect commonly used in cosmetics, and they thus have completed the present invention.
