I have been meaning to get this post up for ages, ever since I first tried this stuff when it came with my Glossybox!
The Alessandro Pro White Nail Polish is desribed as a nail brightener to help brighten the appearance of the nails, as well as cover up unsightly yellowing.
It's basically a clear polish with the slightest blue toned tinge to it. It really does transform dull unpainted nails into nice healthy looking shiny nails. See for yourself...
It's not a UK brand and seems hard to get a hold of here, but I did find it on e-bay for just £3.99 with free P+P. A great deal for something that I think this is a must have. Link!
Have you tried this? Do you love it too?
