Wow! I am definitely loving this! Got one off eBay since it is nowhere to be found in Europe at least, and it works wonders to me. First, it is a very strong moisturizer, leaves me the feeling it is also nutritive for the skin and not only moisturizing, yet not at all oily (my combo skin would reject it in a minute!). It evens out the small imperfections before applying the foundation, as it is supposed to do, and I notice it improves how the foundation stays on my skin: it somehow "disappears" into the skin better and looks more natural.
To conclude, this product does for me everything it claims to be doing, and definitely would go on with more once my tube is finished. The package is quite small (25 grams) but a little goes a looooong way.
