Why does nail polish get really gooey after a while?

finger nail polish is a suspension, the dissolved particles are still floating around and eventually separate
well it gets old and just goes bad, then its harder to use. i am a drama queen though, so this would be no suprise to miy friends that i am answering this!! some crappy brands just dont make them as well. it just dries out from being opened so much and the trapped air in them. some people put nail polish remover in it and it refreshes it, but i dont think it would work. but the wet and wild works great, you could even mix some of them yourself for a fun color just for you. sometimes its good to put them in the refrigerater so they stay fresh. but make sure it is in a bottle that is sealed tight so it doesnt ruin your food. If the bottle was not sealed tight or you had a buildup of excess polish on the rim it will let air get in and start to harden and clump your remaining polish. Also if you let it set and do not shake it before you use it the oil will not dilute it like it should and it can harden. If you do your nails often buying the better brands like OPI helps too with the higher quality.
