I’ve been taking my time working through some of the products in the CK One Beauty Collection. I would have to say that the most noteworthy items are the nail polishes, and the lipsticks. I really like the lipsticks in particular.
My favorites (so far) are the peachy-nude shimmer Lipstick in Brainiac, and the plummy-rose Lip Shine in Blow.
In the US, CK One Beauty is available at ULTA. Internationally, you can get it at Debenhams
