Does La Mer face cream really work? Or is it a big marketing scam?

I purchased it about 2 months ago. It's really works, my skin is combination (normal/oily) and I was sceptical of using it. But it didn't cause me break out and instead balanced my skin. You can see result the next morning after applying tonight. In the morning your skin looks supple and plumed up. I use it only in the evening as it too rich for me during the day. I did so many research before purchase but thought I'll give it a try by myself. Yes, it really works. In fact, I even asked a question on Yahoo, however nobody really knew just that is so expensive. But there are so many products on market that are even more expensive. You need just a pea-size of Cream de La Mer on your face. So a 2 oz. jar will last a year. I live in California and they don't advertize it at all.
