When you reach a certain age, and the lips start to get thinner and thinner, you need a lip liner. If you aren’t at that stage yet, lucky you!
My FAV-OR-ITE lip liner is from NYX Cosmetics. Not only is my favorite because of its staying power, and easy application, but you cannot beat the price! It’s $3.50!
The Natural shade (810) is my favorite, because it blends with any color of lipstick, stain, or gloss I might choose.
You can find the NYX line at Ulta. Some drugstores have started carrying some of the products but I think you can only find the complete line at Ulta.
