Not very effective but maybe with a red liptstick would go better

It's difficult to tell if you're applying this properly because it's very transparent, which is good in a sense because you can wear it with anything. It is a good base for you lip look and let's you colour your lips in more effortlessly with your real lip colour. Though I feel like f you were to purchase a good quality lip product with minimal bleeding it would refer this 15$ product obsolete pretty quickly.

Hard to push up the product, u have to push and spin at the same time. Too much packaging for such a small product! Goes on smooth.

Goes on well, hope it helps to make the lipstick last.

One thing that bugged me about the packaging...after you twist the product up it won't go back again! Product applied smoothly and was invisible on the lips and felt like nothing was on there.

This Invisible lip liner is a great idea!! No need to worry about asking if your girlfriend if your lipstick is smudging!

It's goes with any shades of lip stick its good because no preservatives or mineral oil

I never use lip liner, so I am not sure of this product. Leaves an invisible line, I like the concept of this though but not sure I would use it

Effective however not a high priority in item for some (me included)

Not sure I would spend the money on this since I'm not a big lipstick wearer but I would definitely recommend it to people that wear it a lot. It minimizes the appearance of furrows.
