I use this religiously for both lipsticks and lip glosses and highly recommend it! Keeps colour from feathering all day!

Glides on nicely, will need to try it with a bold colour to gauge its effectiveness

How would I know if it works? My lipstick doesn't usually bleed so I don't need it.

Great concept. Not exactly sure if it'll help my lipstick last longer, haven't worn it for long enough to tell but so far seems good!

Easy to apply. Found it a little sticky. Could go through a lot of product in a small amount of time a little expensive. Took a long time to get the wrapper off

Great idea!! Made lips look more defined with lipstick on! Will use as a combo with all my lipsticks!!

Since I'm not big on the lipstick scene anyway, this wouldn't be something I'd opt to spend my money on. It works great, though, for those who rock the lip colour on the daily!

It seems to work but the areas where the lipstick touches the product seems to ball up the lipstick. Besides that it seems to work well. But do you need it? Maybe if you wore bright colours a lot.

It really helped my lipstick from running off onto my skin and making it look weird

this is the first lip liner that i have tried and i love it! i like how it's invisible too so i can pair it with any colour!
