Review (4/5): Took a lot of tries
Instructions say to keep them on for 5 to 6 minutes and file beforehand. However, I had to do this in multiple sessions (leaving on the gel and then wiping it off so I could chip away the polish). I think my nail stylist mightve used something strong so it was tough to get it off. It was also super tingly/painful and I'm usually not so sensitive. It's effective but definitely don't expect perfect results! Your nails might be dry so I'd suggest having nail oil treatments, cuticle serums etc.
