I wrote this about 2 days ago, which should give you an idea of the staying power. I have now replaced it with $2 nailpolish.
Well the Revlon Color Stay Gel Envy nailpolish definitely didn't last like gel nails. I did my first post about it on the 20th. I've already got the kind of chips I get with normal nailpolish that doesn't even have a sealing top coat. At $16 a bottle, saying I am disappointed is an understatement.
I actually ended up spending more on this nailpolish than I would have on a new set of shellac nails, too!
Sooo many chips :(
So in the end, the only Pro is no UV lamps. I would advise you to stick to cheaper nailpolish, as it has exactly the same results!
Not recommended unless you can get it a lot cheaper and really like the colours.
