Technically this will be going up past midnight on the 6th. :P My bad.
I used my Essence Peel Off Base Coat under this polish. If you want to know more about it and how you can have a go at DIY-ing the base coat, have a look at Alanna @ Pretty Purple Polish's blog post here and Michelle @ LabMuffin's post here. It was my second time using the base coat and I had much more success this time around! I used a very thick coat of it (which took forever to dry) and once it was about half dry, I painted more base coat onto the tips of my nails because it seems to pull away from the tips a bit as it dries. I had no troubles peeling it off my tips this time, whereas last time the polish stuck to the tips.
After running my hands under freezing water
The only time I noticed any colour change - Tips are slightly darker
I'm probably going to try one of the cream colours of the BYS Colour Changing polishes before I make my mind up about them.
