How it works
The panel on this sheet mask names five forms of peptide rather than one: Acetyl Hexapeptide-8, Copper Tripeptide-1, Oligopeptide-29, Oligopeptide-32, Palmitoyl Pentapeptide-4. 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. On this panel it sits alongside Niacinamide, Adenosine and Allantoin. 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.
Key benefits
- Five forms of peptide on one panel, not a single token inclusion
- Niacinamide on the same panel, the formula's active
- Adenosine on the same panel, the formula's active
- Korean GS1 barcode matched against a Korea sourcing supplier's record for this item
How to use
- Once or twice a week after toner, left on for fifteen to twenty minutes then pressed in.
What is the mixsoon Daily Mask Pack Thursday 20ml X 10ea for?
It is a sheet mask from mixsoon's Korean-market lineup, meant to sit in the routine as an everyday routine step. It ships as the same formula sold in Korea rather than a US-shelf reformulation, so the ingredient list on the box matches what Korean shoppers buy.
When should I use this sheet mask in my routine?
Once or twice a week after toner, left on for fifteen to twenty minutes then pressed in. Give it a minute to settle into the skin before layering the next product on top, and keep the same order every time you use it so you can tell what is actually working.
Can I use this alongside other treatment steps?
Yes, it is designed to sit inside a normal routine rather than replace it. Introduce it on its own for the first week so you know how your skin responds, then layer in other treatment steps as usual.
Is this the same formula sold in Korea, or a US version?
This is the Korean-market mixsoon formula, over-labeled in English for US sale rather than reformulated for the US market. The ingredient list on the box is the same one Korean shoppers see on the shelf.
How long does a bottle typically last with regular use?
That depends on how much is used per application and how many steps sit around it in your routine, since a sheet mask used once or twice daily is used differently from one used weekly.

30 of 30 explained
- Water/Aqua 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.
- Methylpropanediol humectant
- Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.
- 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.
- 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.
- 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.
- Tromethamine pH adjuster
- Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
- 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.
- Betaine humectant
- Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
- 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.
- 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.
- Xanthan Gum thickener
- Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
18 more explained
- 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.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener
- This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
- 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.
- Sodium Polyacrylate thickener
- Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the skin.
- 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.
- Caprylic/Capric Triglyceride emollient
- Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
- Hydrogenated Lecithin emulsifier
- Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
- Phaseolus Radiatus Seed Extract plant extract
- Mung bean seed extract, the nokdu of Korean cleansing powders. It carries starches, proteins and saponins and is used as a conditioning, mildly cleansing extract.
- 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.
- Ceramide NP barrier lipid
- Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
- Retinol active
- Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises.
- 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.
- Polyglyceryl-10 Myristate emulsifier
- Polyglyceryl-10 Myristate is a mild sugar-derived emulsifier used to keep oil dispersed in a watery formula.
- Tocopheryl Acetate antioxidant
- Tocopheryl Acetate is a stable vitamin E ester that skin converts to tocopherol. It is used as an antioxidant and a light emollient and holds up better than plain vitamin E in a formula.
- Oligopeptide-29 peptide
- A short chain of amino acids used as a conditioning peptide. Oligopeptide numbers are registry entries, not strengths.
- Oligopeptide-32 peptide
- A short amino acid chain used as a conditioning peptide, usually one of several oligopeptides declared together.
- Palmitoyl Pentapeptide-4 peptide
- Palmitoyl Pentapeptide-4 is the five-amino-acid peptide originally sold as Matrixyl. It is used for the look of fine lines and is one of the longest-standing cosmetic peptides.
