Doesn't work.
I love the colour. That's about it. So at least we have that. I've been wearing this for about a day now with a layer of Seche Vite and it's gorgeous, but there have been no color changes at all with cold, heat or sun. Very disappointed. Thankfully the orange base is a very peppy colour and looks nice, but for the color changing effect it's definitely a waste of money.
