For the ultimate dewy glowy pearly whatever finish, I use CCB over foundation. Pearl is my absolute fave and I have yellow undertones as well, but I am kinda pale. CCB's come in lots of shades so you'll sure find something to match your skintone. They are longlasting and I love love love them because 1. when I use a CCB I dont have to worry about hitting the pan like I do when I use some super exclusive MSF. 2. NO GLITTER!!! Some MSF's contain too much glitter for my taste 3. a little goes a long way so with the 20 € (approx. price in germany), you'll have lots of fun.^^
The CCB's are multipurpose, you can use them for lots of things ( I use them for blush, on the lips, highlighter, eyeshadowbase, light wash of color all over the lid, you can accentuate parts of the body with them...) so IMO, they're an overall great product.
I totaly agree that with powder products, you can look shimmery or load lots of glitter to your face, but if you want to look pearly, liquid highlighters or CCB's are the best.
