I tried samples of this cream, so I wouldn't be able to comment on longer-term effect. I am very picky about products, and my skin somehow always shows straight away when she is not 100% happy, so I could tell quite quickly if something is not good. But this product worked really well after trying on my skin. It is expensive, but the brand tries to pack as many goodies as it can! After trying the sample, I am confident to say this is one product that I would like to buy the full size.
