Amazon Customer 1 I've tried using this twice. First with no top coat, second with required Gel Envy Top Coat. For the first time, the next day after application, the paint on some of my toes disappeared. The second time, I applied it with the top coat, but while I was shopping for pens, I just noticed that my middle paint was gone. And I haven't even washed the dishes or something. I bought this Gel type because Gel Polish at the salon supposedly is long-lasting. But the normal, non-gel I use, last me better (about one to two weeks). On both times, I even used a UV lamp.
