I love the color, but come on I used it maybe 5 x and there is nothing left of it. There is no way to turn it up or get more out of this? Once you sharpen it, it is gone. Not for this price, never again .

I had really high hopes for this, but unfortunately it doesn’t stay put for me. By the end of the day I have raccoon eyes.
On the plus side, the color is rich and the pencil is soft enough that it has a decent glide. With that said, it’s soft enough it does t hold a point so I need to sharpen it after every use (meaning from from eye to the next) if I want to do any sort of precision.

I received this product for free from Pinchme for testing and reviewing purposes. For being my first time trying a ILIA lipliner I really liked the color and how easy it was to apply on my lips. It kind of smudges a bit but still worth using. Stayed on quite good through out the day. Looking forward to trying different shades.
