[product:models-own-lip-sealer--] is intended to be used to seal your lipcolour down so that it lasts all day, through every bite, kiss or sip. It looks like nail polish bth. It comes in a little glass bottle with a brush, just line nail polish does. The lip sealer is a clear, watery liquid, which makes it just a wee bit tricky when applying it on your lips since all you have is a little, thin nail brush to do so. When the liquid hits your mouth it almost stings/tingles a bit, which I thought was weird. But, if the stuff really works, it could be worth it, right? Well, sadly, I don't think it is since I don't find that it makes makes my lipcolour stay or last any better than when I don't use it. If I use a couple coats, I notice that my lipstick stays on a bit better, but a soon as I drink something, that's the end of that, really. It Ali makes your lips feel kinda weirdy-tacky too. So I really don't recommend trying it. Save your money, and buy a long-lasting lipcolour instead.
