I was wondering if fluidline is a product that would dry up, or become old real fast since it is liquid. I really like some of the colors and would like to give fluidline a try. I don't want to buy it if it will dry up in a couple of months.
i think as long as you keep the lid tight and only have it off while you're using it, it should last plenty of time. i've also heard that placing it upside down (so its sitting on its lid) when closed and not in use will make the moisture stay even longer.
Fluidliners do tend to dry up. I was religious about keeping my lids screwed on tight, but they still dried up despite my best efforts. I switched to Bobbi Brown's gel eyeliners, and they not only stay better and have (for me) better colors, but they last a lot longer!
