You can use this as an overnight lip tattoo thing or just apply it as you normally would. I've tried the overnight tattoo thing and honestly, I don't think it's necessary because most of the colour comes off as you're washing your face or brushing your teeth. So if you want a super bold colour rather than a more natural look, don't bother doing applying it overnight.

Lasting power is pretty awesome and you can get away without having to reapply after a meal. The colour is super pigmented and it's pretty easy to blend for gradient lips. The colour I bought is #3 Ruby Shocking. Lee Seyoung wore it in the drama 'The Best Hit' and the colour you see in the drama is pretty accurate to how it looks like in person. The product looks really orange but when you apply it, it's like a nice warm red that's slightly orange. Smells like candy which is nice.
