I recommend this sunscreen.

This is a sunscreen I've been using frequently lately; it's called a "porcelain sunscreen." It really smooths out my skin texture, almost like a primer...? Heh. It seems perfect as a makeup base, and the price seems reasonable too. My skin used to break out from wearing makeup every day, but since this has both sunscreen and base effects, it's my current favorite item. Of course, since it's a sunscreen, the coverage isn't spectacularly good, but I think it's the best among sunscreens!
