I accidentally discovered this varnish Duo Gel L'Oreal in a supermarket and I had tried, I found it very good for a free UV coating, I have not found in the supermarket or in shops like Sephora or Lafayette, so I am led me to Amazon. For a long time I was looking if there was varnishes without lamp UV gels as semi-permanent UV nail lamp clearly assault especially when they must be removed (soaked in acetone for at least 5 minutes ... Etc). There already it's still at least a week without moving and then if I do not want to change color once I added a layer of Top Coat (This varnish is composed of a color and a flask Bottle Top Coat) to revive the shine. I can quietly and stay two weeks. That said, I prefer to change color once a week and enjoy it to aerate my nails. it comes off just like any normal polish remover with acetone-free. I took several colors and still the same good result. I found also without UV gel polish other brands (we are told 3 in 1) as Kate Moss but frankly that's just sweet talk, after three days it starts to crumble like a normal polish . I see that I am in my long comment but frankly for me it varnish is a great discovery, I do not separate myself yet. NB: I'm certainly not a saleswoman, I just always looking for good practical products for my well being. I hope this review helps ...
