Hit and miss..
FAIL: I hate Barry M's new instant (311) 'Nail Effects' which is basically a matte black nail polish that cracks once applied on top of another nail polish to reveal a unique design. Yes, the results are instant and it has an "effect" but it's not that great. On my short nails it just looks like chipped and peeled nail polish and I dislike that the results aren't consistent, sometimes it cracks nicely, and sometimes it bubbles up which leads to an uneven texture. Overall, this is a definite miss from me.
SUCCESS: On the other hand I love Barry M's (244) 'Hologram' nail polish which is clear with chunks of small circular glitter that have a multi dimensional shine. It sounds tacky and childish but I really like it layered over the top of paler colours and grey to really make my nails sparkle. One coat delivers roughly 6 sparkles, I like to add 2 layers to really make them stand out. Also, I would like to add that the glitter is easily removed with nail polish remover.
What's your verdict?
