I finally managed to pick up this much-raved-about product a few weeks ago (thank you Boots and your lovely 3-for-2 offers!) and think I'm just about ready to share my thoughts on it.
This top coat is supposed to be THE best one out there, and I have to admit it is pretty good. I apply a thick layer on top of my nail polish after it's had a few minutes to dry on it's own and the result is a beautifully glossy finish. I also think it makes my nail varnish last a lot longer, and I've rarely seen chips or peeling within the first 2-3 days of wear.
Having said that, I'm afraid that I've actually found the fast drying quality to be a bit hit and miss! The first time I used it, it was incredible - within about a minute I could touch my nails (with a good amount of pressure) and there was absolutely no tackiness. But, the 2nd and 3rd times were completely different. I did eventually get the hard, non-tacky result achieved before, but it took soo much longer. And, in the meantime I managed to make dents in the varnish from all of the tapping to see if it had dried! I did use different brands of nail polish each time (Essie for the first, Rimmel for the 2nd and No. 7 for the 3rd) so perhaps this is where the issue lies. In my opinion though, such a celebrated product should perform effectively every time.
The jury is still out on this one. I'll keep using it because I love the shiny finish and the fact it keeps my varnish looking good for longer, but I'm not sure if I'll be re-purchasing when it's all gone...
