I know this thread is old, but you should never wear polish without base and top coat. Maybe you got old polish or someone added polish remover to make the bottle look full. The product definitely sounds like it has been altered.
Other than than that I absolutely love Zoya!!!! I just bought about 10 more bottles a couple of weeks ago. I also use Armour and Anchor. My hands are in water pretty much all the time and I still get a weeks wear. I have had Zoya polish on my toes for two weeks without chipping.
