B.B. Creams?

"Bb cream originated in Germany and was used by Dermatologists as a healing aid for their patients, who have gone through laser skin surgery and also on patients who has burn; this cream can help to smooth and regenerate the skin" (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140443399667). An Asian client went into Sephora, and she asked for a B.B. cream. I heard B.B. creams are the latest craze from Korea to Japan and now making its way to the U.S.A. In Korea, B.B. is suppose to stand for Blemish Balm. I was told Boscia is coming out with a B.B. cream soon, but just because blemish balm is what it stands for it is not just for pimples. B.B. creams have a category of their own. They help even out the complexion like a tinted moisturizer- but it is not makeup. So let's get things straight, a B.B. cream is a treatment for blemishes, looks like a tinted moisturizer but is not in the makeup category, gives radiance, sun protection, and is anti-wrinkle as well.
Has anyone tried a B.B. cream? What do you think of it?
