MAC has a pretty good new foundation and concealer out as part of their Well Defined collection. The Studio Sculpt foundation incorporates silicone, which I particularly like. It also includes SPF 15. In addition, the collection has a full coverage Studio Sculpt concealer.
From the company literature:
Well-Defined brings to life over two years of work backstage in the lab to perfect our newest foundation and concealer. Studio Sculpt SPF 15 Foundation is a rich, luxurious Cream Foundation in tube. This lush uniquely textured foundation delivers ultimate hydration while instantly revitalizing dull and dry skin. Smooth and even application yields a medium buildable coverage with a natural-satin finish. It’s paired with Studio Sculpt Concealer, which provides full-coverage that never becomes dry and cakey with a gel-based cream formula slips onto skin, effortlessly hiding imperfections.
Look for the MAC Well Defined collection beginning February 7, 2009. Also, don’t forget that the Hello Kitty collection will be available shortly after that (I’m saving all of my monthly cosmetics budget for that one!)
