Aqua and hyaluronic acid
Water first, then a humectant that holds it in the top layers. This is the part that makes it work under the device, and the part that makes skin crease less.
Why it pairs
Water based · 17 ml · rolling applicator
A water-based eye cream with snail peptide, hyaluronic acid and niacinamide, in a tube with a cooling steel rolling ball. We did not formulate it. We found it, tested it, and put our name on it.
Roll it under each eye, pat the rest in, then put the device on.
Before you buy it
We are not a lab. We tried a run of creams meant to sit under the device, kept using this one, and put it into KiRei packaging rather than pretending we invented the formula.
That is also why it is not priced like a luxury eye cream. It is a good water-based cream with a cooling roller, and that is all we are claiming for it.
If you would rather use a cream you already own, do. The only thing that matters for the device is that whatever goes on is water based and still damp ten minutes later.
Buy it from us, or do not. Just do not run the device on dry skin.
What is in it
Taken from the maker's own ingredient panel and carton.
Water first, then a humectant that holds it in the top layers. This is the part that makes it work under the device, and the part that makes skin crease less.
Why it pairsThe ingredient this whole category is built on. It is a humectant and it forms a light film. Well liked, not a miracle.
Surface levelAcetyl hexapeptide-8 and hydrolyzed collagen. Hydrolyzed collagen is a large molecule that sits on the surface and holds water. It does not travel down and become your collagen, whatever the category says.
Not what it claims elsewhere
How to use it
Thirty seconds before the ten minutes.

Nothing else on, so there is no barrier between the cream and the skin.

The steel ball is cold. Roll under each eye, then pat the rest in with a fingertip.

Put it on while the cream is still damp. Ten minutes, then it switches itself off.
On dry skin the pulses feel like almost nothing, so people turn the intensity up and still feel almost nothing. A damp layer fixes that. It is the single most common reason someone says the device does not work for them.
The pair
This is not a bundle badge. It is the step most people skip, and it is why they say they cannot feel anything.


The electrical pulses need a damp surface to spread evenly across the skin. On dry skin you feel almost nothing, turn it up, and still feel almost nothing.
Water works. A water-based cream works better, because it stays put for the full ten minutes instead of evaporating. This one leads with aqua and hyaluronic acid, and the rolling ball puts it exactly where the pads sit.
Buy it from us or buy any water-based eye cream you like. We would rather you use the device properly than buy a second one.
Both together $78
Heads up on delivery: the cream ships from a US warehouse in about 3 to 5 days, the device takes 8 to 15 days from overseas. Ordered together, they will usually arrive separately.
Questions
No. You need something damp under the pads. Water works, this works better because it stays put for the full session. Any water-based eye cream will do the same job.
No. We source it, we tested it against the alternatives, and it ships in KiRei packaging. We are claiming we picked it well, not that we invented it.
17 ml, which is 0.57 fl oz. Used once a day under both eyes, most people get a couple of months out of a tube.
Aqua, hyaluronic acid, snail secretion filtrate, hydrolyzed collagen and acetyl hexapeptide-8, per the maker's panel. The carton also lists niacinamide.
It is an eye cream, so it is made for that area, but keep it out of your actual eyes. Patch test on your inner arm first if your skin reacts easily.
No. Snail secretion filtrate is an animal-derived ingredient.
It ships from a US warehouse, usually 3 to 5 days. The device ships from overseas and takes longer, so if you order both they will probably arrive separately.
It is a cosmetic. It hydrates, it sits on the surface, and hydrated skin creases less and catches light better. It will not change pigment or move a fat pad, and we are not going to tell you it will.
In short
That is the entire pitch. No percentages, no origin story, no claim that a cream is going to do something a cream cannot do.
