The L'oreal, true to it's name, smells like a crayon. It bothers me a bit. This is an automatic lipliner and the color goes on smoothly with no problems. It feels a tidge "stickier" at first but that goes away.
The Sephora Red lipliner is a cute 3". People have expressed how upset they were that it's a brick red as opposed to just a red. Well, I've taken a picture, and see for yourself, which is the brick here?! This lipliner glides on very smoothly with non of the slight stickiness I experienced with the L'oreal. And it doesn't smell like crayons.
They're both relatively easy to remove- although not so easy that they would come off all the time on you. The L'oreal costed me about $8, and the Sephora, $3. I can tell you that I'll be putting the Sephora under my lipsticks. I prefer to keep my lipsticks on the more neutral side, and the L'oreal just takes it too far over to the warm side. It made my MUFE Artist Intense Lipstick in #44, a slight cooler toned lipstick turn obviously warm colored. Which confused me and led me to believe that I didn't like the lipstick as much as I actually do.
I wanted to check to make sure my eyes weren't playing tricks on me, so here's the comparison of the two lipsticks layered on top of the two lipliners. Sure enough, just a leeetle bit more brick with the L'oreal.
