13 Beauty Products You Absolutely Must Buy in November

The ingredient list on the 111 Skin Celestial Black Diamond Bio Cellulose Eye Masks ($170) reads like an antiaging addicts' dream. There are peptides, hyaluronic acid, rose hip extract, and retinol in every patch. I like to use these under-eye treatments while I put on my foundation and eye makeup (a trick I learned backstage at New York Fashion Week). The fabrics absorb any fall out from eye shadow, while working to minimize fine lines and dark circles. So when it's finally time to put on my concealer, the corrector blends in smoothly without creasing.
