It's the perfect winter primer for filling in wrinkles and fine lines.

Winter is a difficult time to keep your skin smooth looking. Not only are you dealing with flaky, dry skin from the cold outdoor weather, but you may also be experiencing the occasional blemish and an oily t-zone because of indoor heating and not getting a great deal of fresh air. Get the best of both worlds (and a flawless foundation for your makeup) by trying Smashbox's Photo Finish Hydrating Foundation Primer ($42, Sephora). It's oil free, so it won't clog pores or look greasy, but will still give your face a moisture boost to keep skin looking young and soft. Apply a small amount to clean skin and let stand for a few minutes before applying makeup.
