I'm not sure why people go crazy for this product. I tried with different MAC lipsticks (including matte and sheen types) and noticed absolutely Zero difference. I don't think I can even call it a lip balm b/c my lips didn't feel any better when using it under the lipsticks as well. I'm sticking to a bit of clear balm instead of wasting $$.

I love this stuff - it is so smooth, so light. It also helps lipstick stay exactly where you put it.

I have stashes of this good stuff. It's the ONLY thing I wear on my lips under MAC matte lipsticks. It's moisturizing and when it wears off I re-up. I keep spares in all my bags I never want to leave without it.

Use this lip primer every day! It’s smooth and gentle on the lips and keeps my lipstick looking fresh.

It’s hard to believe how great this works! I apply it then apply lipstick and sometimes I wake up with lipstick still there.

Once you apply this to your lips (before you apply lipstick) lightly rub your lips together lightly and allow it to set for about a minute or two. After it has set, THEN apply your favorite lipstick. It really helps my lipstick from moving around. I was applying it incorrectly before. Love this product, it really works!

It’s perfect, no too slimy yet moisturizing

I bought this product, it did not smooth or hydrate my lips and lipstick came off as soon as I ate. Not worth the money! You are better of using chapstick for hydration.
