A lot of people really underestimate the magic that a good blush can do. If you are the type of gal who doesn't wear much makeup, you really only need some mascara and blush to look put together.
My new love is Mark's Just Pinched Instant Blush Tint. I like the "Cheeky" shade because it looks quite natural against my so-pale-it-is-almost-transparent skin. There are three other shades to pick from for peeps who have normal skin tones, too.
The great thing is that this blush is so blendable, yet stays in place all day. That is a rare find. For $6 it's worth a try!
