How it works
The Plum Peptide Plumping Gel Mask is a sheet mask, used after toner, in place of your serum step, in the evening. The peptide it is built around is Acetyl Hexapeptide-8, named fifty-first on its own ingredient list. The same list carries Niacinamide, Allantoin and Adenosine, so the peptide is not the only thing on it worth naming. How much of the Acetyl Hexapeptide-8 stays on the skin, and for how long, is decided by the sheet mask format rather than by the list alone. This is the Original Korean Formula, the sheet mask Isntree sells in Korea, Acetyl Hexapeptide-8 and all.
Key benefits
- Acetyl Hexapeptide-8, the peptide this sheet mask is built around
- Niacinamide, Allantoin and Adenosine on the same list, actives
- Cyanocobalamin on the same list, a vitamin
- Tocopherol and Glutathione further down the same list
- Hydrolyzed Vegetable Protein and Hydrolyzed Collagen further down the same list
- Acetyl Hexapeptide-8 named fifty-first on the manufacturer list printed on this page
Key actives
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 the entry this sheet mask is named after, and the list carries it.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. The panel names it fifth on this sheet mask's list, beside Acetyl Hexapeptide-8.
Allantoinactive
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. The panel names it twenty-first on this sheet mask's list, beside Acetyl Hexapeptide-8.
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-fifth on this sheet mask's list, beside Acetyl Hexapeptide-8.
Cyanocobalaminvitamin
Cyanocobalamin is vitamin B12, and it is a deep pink-red, which is why a formula carrying it often has a colour nobody added on purpose. It is used as a conditioning vitamin. The panel names it forty-second on this sheet mask's list, beside Acetyl Hexapeptide-8.
Where does this sheet mask go in my routine?
After toner, in place of your serum step, in the evening. Toner goes on before it, and the rest of the routine goes on after you take the sheet mask off. 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 Acetyl Hexapeptide-8 and not three changes at once.
Is this the Korean-market sheet mask or a US version?
The Korean-market one, Acetyl Hexapeptide-8 and all. We match this sheet mask 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 Acetyl Hexapeptide-8?
Niacinamide, Allantoin and Adenosine. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Acetyl Hexapeptide-8 sits relative to them. Further down the same panel: Cyanocobalamin, Tocopherol and Glutathione.

How to use
- Cleanse and tone first so the mask sits against a clean surface rather than the day's residue.
- Unfold one sheet, settle it over the face and smooth out the air pockets around the nose.
- Take it off after about twenty minutes and pat the remaining essence in rather than rinsing.
- Do not leave it on until it dries out, because a drying sheet starts pulling water back off the skin.
Worth knowing
- Patch test this sheet mask on a small area and wait a day before using it more widely, especially with Acetyl Hexapeptide-8 on the list.
- Introduce this sheet mask on its own for the first week, so anything your skin does is traceable to the Acetyl Hexapeptide-8 rather than to three changes at once.
