How it works
The Peptide Pore Tension 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 thirtieth 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 ilso sells in Korea, Acetyl Hexapeptide-8 and all.
Key benefits
- Acetyl Hexapeptide-8, the peptide this sheet mask is built around
- Niacinamide, Allantoin, Adenosine and Methyl Diisopropyl Propionamide on the same list, actives
- Dipotassium Glycyrrhizate and Copper Tripeptide-1 further down the same list
- Lactobacillus Ferment Lysate and Alteromonas Ferment Extract further down the same list
- Acetyl Hexapeptide-8 named thirtieth on the manufacturer list printed on this page
- The Korean-market release of this sheet mask, confirmed against its Korean barcode
How to use
- Unfold onto a cleansed face, leave on for fifteen to twenty minutes, then remove and pat any remaining essence into the skin.
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: Methyl Diisopropyl Propionamide, Dipotassium Glycyrrhizate and Copper Tripeptide-1.

Ingredient list read from jolse.com on 10 September 2026.
25 of 32 explained
- Purified Water solvent
- Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
- Glycerin humectant
- Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
- Dipropylene Glycol humectant
- Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- Niacinamide active
- Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
- Glycereth-26 humectant
- Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
- Panthenol humectant
- Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
- Trehalose humectant
- Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
- Allantoin active
- 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.
- Hydroxyacetophenone preservative booster
- Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
- Arginine amino acid
- Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
- Carbomer thickener
- Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
13 more explained
- Glyceryl Glucoside humectant
- Glyceryl Glucoside is glycerin bound to glucose, from the resurrection plant. It is a humectant that holds water in the outer layer of skin.
- Ethylhexylglycerin preservative booster
- Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
- 1,2-Hexanediol humectant
- 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
- Adenosine active
- 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.
- Disodium EDTA chelator
- EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.
- Sucrose Cocoate emulsifier
- Sucrose Cocoate is table sugar joined to coconut fatty acids. It is a very mild emulsifier and cleanser that also holds water, so it turns up in gentle cleansers and toners.
- Lactobacillus Ferment Lysate ferment
- Lactobacillus Ferment Lysate is the ferment with the bacterial cells broken open, so their contents are in the formula too. It is a conditioning ferment used in barrier-focused products.
- Sodium Hyaluronate humectant
- Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
- Methyl Diisopropylpropionamide active
- A synthetic cooling agent that gives the cool feeling of menthol without the mint smell. It is used where a formula wants the sensation but not the scent.
- Dipotassium Glycyrrhizate active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- Silk Extract protein
- A water extract of silk fibre, carrying sericin and fragments of fibroin protein. It is used as a conditioning protein that dries to a smooth, soft film.
- Acetyl Hexapeptide-8 peptide
- 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.
- Copper Tripeptide-1 peptide
- Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines.

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.
