Mary-Lou Manizer Highlighter from The Balm Cosmetics $24 (cheaper on Hautelook when available)
This is a powder highlighter. It is more on the gold/yellow side, and will brighten up the high points of your face. This is my absolute favorite highlighter. A little goes a long way and it blends out wonderfully. 5/5 definitely. If you want a more subtle highlight that is more on the pink side, check out their Cindy- Lou Manizer. You can find these online at TheBalm.com or at select Kohl's stores. (also check Hautelook for better deals.
