How it works
Niacinamide leads the ingredient panel on this sheet mask. 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. On this panel it sits alongside Adenosine, Allantoin and Methyl Diisopropyl Propionamide. 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.
Key benefits
- Niacinamide named on this product's own ingredient panel, near the top of it
- Adenosine on the same panel, the formula's active
- Allantoin on the same panel, the formula's active
- Korean-market formula, with its Korean barcode and batch code intact on the box
How to use
- Use this mask as a weekly care step after cleansing. To apply, apply according to the format, leave on for the stated time, then remove and continue with the rest of the routine. Keep it to PM unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step.
What does the Zero Pore Cooling Mask 27g X 5ea actually contain?
Its ingredient list is led by Niacinamide, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.
How do I use the Zero Pore Cooling Mask 27g X 5ea?
Use this mask as a weekly care step after cleansing. To apply, apply according to the format, leave on for the stated time, then remove and continue with the rest of the routine. Keep it to PM unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.
Is the Zero Pore Cooling Mask 27g X 5ea the same formula sold in Korea, or a US version?
This Zero Pore Cooling Mask 27g X 5ea is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.
Can I use the Zero Pore Cooling Mask 27g X 5ea with other actives in my routine?
Yes, as long as it is used in its own step, a weekly care step after cleansing, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.
Who is the Zero Pore Cooling Mask 27g X 5ea suited for?
It suits most skin types looking for weekly care step after cleansing rather than a single acute problem. Check the listing for the exact size in stock. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

27 of 27 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.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- 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.
- Saccharide Hydrolysate humectant
- Saccharide Hydrolysate is a mixture of plant sugars broken down for use as a humectant. It holds water in the outer layer.
- 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.
- 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.
- 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.
- 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.
- 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.
15 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.
- 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.
- 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.
- Methyl Diisopropyl Propionamide 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.
- Indigofera Tinctoria Extract plant extract
- True indigo extract, the plant natural indigo dye is made from. In a formula it both colours and conditions.
- Hemerocallis Fulva Flower Extract plant extract
- Orange daylily flower extract, from an edible flower in Korean cooking. It is used as a conditioning floral extract.
- Oenothera Biennis (Evening Primrose) Flower Extract plant extract
- Evening Primrose Flower Extract is used as a conditioning plant extract. The seed oil of the same plant is the better known part, and it is a different ingredient.
- Pinus Palustris Leaf Extract plant extract
- Pinus Palustris is longleaf pine. Its needle extract carries plant antioxidants and appears in Korean formulas alongside other conifer extracts.
- Pueraria Lobata Root Extract plant extract
- Pueraria Lobata is kudzu. Its root extract carries isoflavones, plant compounds structurally similar to oestrogen, and Korean formulas use it for the look of thinning, less resilient skin.
- Ulmus Davidiana Root Extract plant extract
- Ulmus Davidiana is Japanese elm, whose inner bark yields a naturally slippery mucilage. Korean formulas use the root extract for that cushioned feel and for the look of reactive skin.
- Myosotis Sylvatica Flower/Leaf/Stem Extract plant extract
- Forget-me-not extract, taken from the whole plant above ground. It is used as a gentle conditioning botanical.
- Camphor fragrance component
- Camphor is the aromatic compound distilled from the camphor laurel. It has a sharp medicinal smell and gives a cooling feel as it evaporates.
- Palmitoyl Tripeptide-5 peptide
- Palmitoyl Tripeptide-5 is a fatted three-amino-acid peptide used for the look of firmness and fine lines. The palmitoyl tail is what lets it cross an oily surface.
- Hydroxycinnamic Acid antioxidant
- Hydroxycinnamic Acid is the parent compound of the plant acid family ferulic and caffeic acid belong to. It is used as a plant antioxidant.
- Rutin antioxidant
- Rutin is quercetin with a sugar attached, which makes it far more water-soluble. It is a plant antioxidant from buckwheat and citrus peel.
