These work exactly the same as those fake tattoos you had when you were a kid but now as an adult it's more tricky and you've got to work around your lips. You need to make sure that the transfer you pop out is measured to your lips, this involves using scissors to cut to your shape, placing it as accurately as you can (which I wasn't good at), then wetting it with cotton wool and water. After that you have to slowly peel it off which can be tricky as the tattoo can stretch and go gloopy if you're not careful. The most important thing from then on is you need to wait 5 mins for it to set and dry, I found the process quite uncomfortable since I have quite a habit of pressing my lips together, yet alone you start to realise that you move your lips a lot.
I found that they crinkle at an kind of lip movement, they also exaggerated the natural creases in my lips.
The lip tattoos felt way too heavy and uncomfortable for me, so I had to peel it off, so I can't really judge how they wear, I don't think they will hold up to the time they tell you (4-8 hours) as these have a tendency to peel off on their own. Anyhow I am a type of person that still can't get along with false eyelashes, others may find these a breeze to wear.
Overall I think these are an amazing idea just too time consuming and personally they really don't work for me. I can see why some love them, especially when you can get a knack of a good measurement and keep your lips relatively still for at least 5 minutes which I couldn't cope with, you'll definitely see better results. The vast amount of patterns and shades out there is outrageous and I love the glitter finishes as there is so much glitter, just it feels exactly the same as the one without.
My measurement was really inaccurate on my first try you can see where the sides wrinkled up on the edges, I tried to get away with breaking some off but it peeled so a I made a fail on my first go.
