Hydrating :) I like to use this after a lip scrub, or after I've been wearing lip products too often.
21 is too pink, 23 is a bit too yellow, I mix it with another foundation to get the correct shade. Over all, it's decent. The brush is okay, but it gets a bit tricky when it comes to cleaning because the brush is on the other end of the foundation stick.
brightening is my favorite one :)
