Quite expensive for such a brand though it does feel nice and smooth on the skin when applied. From my experience it's rare to find anti aging serums that feels like that actually.
Did firm the skin up a little. It was quite light and did not irritate my oily skin either.
First opinions are that its quite watery on the hand, but takes some time to absorb fully into the skin. However, my skin does feel smoother and more moisturized when I have this serum on.
