I received a sample of Revive Eye Renewal Cream in an pre-christmas order from SpaceNK, and I've eked out the sample for about three weeks, to see how it compares to the Sarah Chapman Eye Recovery I love (this was one of the very first things I reviewed on this blog here and I've been using it since Christmas 2008).
The Revive Eye Renewal Cream isn't a cream at all to me; it's a light, clear gel. I was concerned that it wouldn't be moisturising enough for my dry under-eye skin, but surprisingly it does appear to be able to hydrate and moisturise well, likely due to the EGF (epidermal growth factor), a polypeptide that is marketed as 'responsible for creating dynamic and fast moving cell activity, leading to a youthful and radiant complexion'. I personally have doubts that this ingredient is small enough penetrate to the basal layers of the epidermis where new skin cells grow. Whatever, it's good at hydrating the skin.
I did notice a slight tightening effect from the Revive when I applied it, and a benefit of this cream is that you can also apply it to the upper lid (I'd recommend applying on the brow bone rather than directly to the lid personally - it will travel to the lid as you blink). It's not quite as hydrating as the Sarah Chapman, but my eyes haven't felt tight or crepe-y while I've been using it, and my fine lines are no worse (or better) than when using the Sarah Chapman.
Summary: I'd recommend the Revive if your primary concern is slackening of the skin around the eyes, and particularly on the lids. For my dry but not slack skin, I'm sticking with the Sarah Chapman (which is £30 cheaper for the same amount).
