It is currently available (in 8 shades) in the US exclusively at Sephora. (It has got a few positive Beautyinsider reviews.) It will be launched in Japan on February 18th (in 6 shades).
As for CK Calvin Klein in the UK, I noticed that the counter in London’s House of Fraser had disappeared. I am not sure whether it has moved to another department store or whether the line has pulled out of the UK market. I will look for further information and I will keep you posted.
