If there is a MAC Cosmetics product that I swear by it has to be the, Prep + Prime Fix +. It is so good, it is very refreshing and makes makeup looks smooth and flawless. It's great for both dry and oily skin.
MAC lip primer - a necessity if you wear lots of red lipstick like I do. It fills in the lines of your lips and keeps it on all night. It also acts like lip balm. Plus, it seems to never end - totally worth the your pennies. Trust me!
