How it works
The Caffetinal Cream is a 50ml cream, used as the last skincare step, morning and evening, over serum. The active it is built around is Niacinamide, named tenth on its own ingredient list. The same list carries Caffeine, Adenosine and Retinal, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the cream format rather than by the list alone. This is the Original Korean Formula, the cream KAINE sells in Korea, Niacinamide and all.
Key benefits
- Niacinamide, the active this cream is built around
- Caffeine, Adenosine and Retinal on the same list, actives
- Acetyl Hexapeptide-8 on the same list, a peptide
- Tocopherol and Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate further down the same list
- Cholesterol and Ficus Carica (Fig) Fruit Extract further down the same list
- Niacinamide named tenth on the manufacturer list printed on this page
Key actives
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this cream's own ingredient list it is named tenth.
Caffeineactive
Caffeine constricts small blood vessels near the surface, which is why eye products use it for the look of puffiness and shadow. It is water soluble and works only while it is on the skin. The panel names it eleventh on this cream's list, beside Niacinamide.
Adenosineactive
Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated. The panel names it thirty-eighth on this cream's list, beside Niacinamide.
Retinalactive
Retinal is retinaldehyde, a vitamin A derivative one chemical step closer to retinoic acid than retinol is. It is yellow-orange and unstable in light, so products carrying it are usually opaque. The panel names it fortieth on this cream's list, beside Niacinamide.
Acetyl Hexapeptide-8peptide
Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable. It is named sixtieth on this cream's list, alongside Niacinamide.
Where does this cream go in my routine?
As the last skincare step, morning and evening, over serum. Anything thinner than a cream goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Niacinamide and not three changes at once.
Is this the Korean-market cream or a US version?
The Korean-market one, Niacinamide and all. We match this cream to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Niacinamide?
Caffeine, Adenosine and Retinal. The order they are printed in on this cream's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Acetyl Hexapeptide-8, Tocopherol and Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate.

How to use
- Smooth over the face as one of the last steps of a routine, morning or night.
Worth knowing
- Patch test this cream on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- Retinal is on this list, so keep this cream to the evening and build the nights up slowly rather than starting nightly.

It has also been proven that caffeine stimulates lipolysis, which Lupo et al postulated may contribute to improvements in lower eyelid sagging and puffiness.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
