NARS Pure Sheer SPF Lip Treatment- I've only been using this for a few days. So far, I love it. It has spf 15 which is awesome in summer! Also- it doesn't feel like lipstick. I'm not to hot on the feeling that most lipsticks have- the feeling of stuff on the lips. But this I can tolerate- it's a little dryer than a chapstick, and feels thinner on the lips as well. It seems to be softening my lips as well. It gives only a very sheer wash of color, making it ideal for a workplace that only tolerates light use of makeup. The color can be built up, but the max amount of color is only going to make your lips appear bitten- you're not going to get a Ton of color from it. The product doesn't seem to accentuate any cracks, which is also nice.
So far, I'm loving it, and will probably use the whole tube and repurchase. The color selection isn't great, but again- this product isn't really about the color, it's about the spf.
