Review (5/5): I love this cream
I love this cream. It's thick enough to feel like it's doing the job, but not heavy or greasy. It smells amazing. I've been using it for a couple of weeks, and I can already see an improvement in overall skin tone and texture. A little goes a long way, which makes the price point VERY reasonable.
As for "fake" products, I haven't gotten one, but if you see the same product listed at drastically different prices, it's safe to assume that the cheap one may not be authentic or fresh. A good jar of this cream should have a fairly thick consistency and smell like fresh citrus.
