I learned about BB creams from Izzy (aka Muse) @ Musings Of a Muse. She's pretty awesome in my opinion, because she does great reviews and is incredibly informative. She also does tons of reviews on Asian beauty products. You can see her reviews for Korean products here and Japanese products here. She was part of the reason I got into these products, because the packaging is just so insanely cute and they do have some great products for small amounts.
Now I'm not going to go extremely in-depth about BB cream. She has a full explanation here. In the most basic terms: your BB should be able replace moisturizer, SPF, foundation. Many have the ability to help with acne, as well as whitening ingredients or to help reduce scars. It should have anti-aging. The Asian branded BBs have these functions but Western "BBs" fall short of these things.
The Asian BBs have a creamy consistency and some are watery (which there are BBs that are labeled with water, watery, etc!), thinner but most have nice coverage. The Western "BBs" are more like tinted moisturizers in the fact they lack the things real BB cream would do: anti-aging, taking care of acne, moisturizer, most lack coverage and don't have very good SPF or none at all! In a nutshell, many Western "BBs" are just tinted moisturizers with "BB cream" slapped on top. Izzy has reviewed so many and give you a variety of options.

I've settled on the Hot Pink BB since summer will be coming on soon for me and my face turns into an oil slick. So not a pretty sight... My current foundation is rather heavy for the summer and feels like a mask on with all the heat, sweating and oil.
There are a variety of things to determine whether or not you have a real bottle. Since SKIN79 changes their packaging so often, as states above, they keep certain markers to identify a real bottle.
