I love special effects in polish, and I recently had the opportunity to try out Ylin Mood Changing Polish from Born Pretty Store.
This polish changes from yellow (warm) to green (cold) - it's summer here at the moment (albeit a cool summer), so the colour change wasn't super obvious. It's opaque in 2 coats, but I used 3. It's a tad streaky and chalky, but it evens out easily.
The colour change is a lot more responsive to temperature than the BYS ones I've tried in the past - it's almost instantaneous! I love the green, but the yellow doesn't quite suit my skin tone. Next time, I might try the blue/purple version instead.
Born Pretty stocks a massive range of nail art supplies and polishes, with worldwide free shipping (hurray!). You can use this code NYL91 for a 10% discount.
