Today I did lip swatches of a matte NYX lipstick I got a while back. Because Matte lipsticks have a tendency to show any imperfection in lip texture I exfoliated my lips before hand with Fresh Sugar Lip Polish:
You can get it at Sephora for $22.50 and it works really well but you can get the same results from an at home exfolliant for way less from things you already have in the kitchen!
Take olive oil and add a pinch of brown sugar.
Dab on your lips and let sit for a minute.
Then take a wet wash cloth, or use your finger, and gently rub it back and forth. Rinse with water.
Apply a lip balm or a moisturizing lipstick afterward.
WAH-LAH!! Works just as well as the Fresh exfolliant above and you can save that money to buy more Matte lipsticks!
