Zoya Renew Nail Polish RejuvenatorNot sure...
It worked pretty well, but it took waaaaaaaay more than one drop to work on my armor top coat which had thickened.
But more importantly, this stuff disappears! I bought a bottle, used two squirts in my armor polish, a few weeks later I looked at the bottle and it was half empty. Used two squirts again, and again a week later the bottle is almost empty, well below the dropper so I can barely get it out.
What do I have to do to keep the elves from stealing this stuff from me? Feels like a waste of money, I only used it twice, so it hasn`t really saved me much of anything
