It's all about multi-tasking! YSL's brand-new Babydoll Kiss and Blush ($40 at yslbeautyus.com) is adorably packaged, small enough to fit in the tiniest clutch and it's both a lipstick and a blush. Can we get an "Amen?" The innovative formula is a fusion of two technologies: foundation and lipstick. The air-whipped consistency, with two patents pending, combines a blend of pigments for color harmony perfectly adapted to both lips and cheeks. It blends easily and evenly and diffuses light for a finish that is both matte and luminous. The price is a little steep, but it's working double-duty and a little goes a long way. It comes in 12 flattering shades but so far, No. 2 Rose Insolent is our favorite.
