Meh. It's just OK. It's a great moisturizer and doesn't irritate my sensitive skin, but doesn't do much for the fine lines around my eyes, which is what I bought it for. It's a two-part system with a cream in the lower half of the jar and a serum on top. The serum seems completely useless. It is seriously nothing more than a very rich moisturizer. Plus it's spendy for the tiny little jar. Look elsewhere if you want something effective for fine lines.
