One thing that could be improved, in my opinion, is the formula. After a couple of hours it gets dry and crumbles so needs re-applying. Also, when you apply it you may need two layers as the formula is not as opaque as it could be.
So there was my little review of the Little Mix Loves Liquid Liner. Overall I would rate it a 6/10. It is perfect for if you are on a tight budget like I am, but if your looking for a high quality product I would recommend another brand. But still, it does a good job for £2.99.
