BYS is a cheap Australian cosmetics brand - they do a bit of everything,
including polishes and eyeshadows. One of their coolest ranges is the Colour Change collection, which is full of polishes which change colour
in different temperatures. I've found that winter is a great time for
wearing these - I'm not sure you'd get the cool shade at all during
summer! I've shown you the Blue version before, now here's the Green:
I took these right after getting out of bed, so you can see the cold creeping across my nails! First off, it needs 5 coats to hide the nail line, which is annoying. Also, the pale "warm" colour looks weird on my skin, although I love the murky green "cool" colour. But the sheerness means that maybe I'll be able to do colour changing glitter gradients in the future :)
Have you tried these before? Would you want to?
