Finally received my Missha BB cream I bought from ebay around 2 weeks ago. I have used this for a few days, I must say I am impressed. At the start when you put it on, it does give you a gray cast but that does go away after 20 seconds you wouldn't even notice it anymore. Coverage is good, pretty much covers my uneven skin tone as well as acne scars. I like to put it on and then set it with powder. I'm currently using MAC mineral loose foundation, not the best powder to be using to set the BB cream but it will do for now. Once you set it with powder, it should last the whole day. This might sound gross but sometimes I go gym after work with make up still on and it pretty much stays in tact but then I don't really sweat like a pig so it might be different for everyone lol
Overall, really impressed and definitely buy again.
Hope this helps anyone who is deciding between the two.
