I picked up some instant artificials after hearing about it on the nail board. I couldn't wait to try it, I've heard great things. I've been using it now for about 2 weeks, and I really like it. It takes a while to dry, but I think it's worth it. Worn alone it leaves nails shiny and hard, and you can use it as a base coat also. I don't know it if makes polish last longer, cuz honestly I change my polish too often to find out. You can find it at sallys beauty.
