How it works
The Porexel line targets visible pores, and this serum builds toward that with Niacinamide for tone and texture, Ceramide NP to support the barrier around stressed pores, and Sodium Hyaluronate and Polyglutamic Acid for hydration that plumps the surrounding skin. Adenosine and Resveratrol sit alongside less common inclusions like Ectoin and Nicotinamide Mononucleotide, and a run of botanical extracts, including jasmine, willow bark and grape, fills out the supporting cast. It is meant to follow toner and precede a moisturizer, applied to skin that is still slightly damp so the actives have a receptive surface to absorb into. This particular listing is the 40ml size TIRTIR sells for the line, packaged and formulated for the Korean market rather than a separate US release.

- Sodium Hyaluronate and Polyglutamic Acid for hydration
- Adenosine, Resveratrol and Ectoin in the supporting formula
- Sold as TIRTIR's authentic Korean-market formula, the same version sold through Korean retail rather than a US-reformulated substitute
Inside the formula
Inside the formula
Will this shrink my pores permanently?
No topical product changes pore size permanently. What this serum does is support the surrounding skin's texture and hydration, which is what actually makes pores read as less visible day to day.
Is this a daily-use serum?
Yes, it is formulated as a standard AM/PM drop serum rather than a periodic treatment, so it fits into a routine every day. This is general guidance rather than a fixed rule, so adjust it based on how your own skin or the product itself responds.
Does it feel dewy or matte on application?
Dewy, as the name suggests. It sits with a slightly tacky, hydrated finish rather than drying down matte. This is general guidance rather than a fixed rule, so adjust it based on how your own skin or the product itself responds.
Is this the same formula sold in Korea, or a version made for the US market?
This is TIRTIR's Korean-market formula, sourced and shipped with its original Korean-market packaging and batch coding rather than a separate US-reformulated version. Korean Pharmacy stocks the exact SKU sold through Korean retail rather than a substitute built for US shelves, which is the point of buying from a specialist rather than a general beauty retailer.
How should I store this to keep it in good condition?
Keep the cap or compact closed between uses and store it away from direct sunlight and heat, the same way you would any cosmetic. A cool, dry spot such as a drawer or cabinet keeps the texture and finish consistent for longer than leaving it exposed on a warm windowsill or in a hot car.

Ingredient list read from tirtir.global on 10 September 2026.
59 of 59 explained
- Water/Aqua/Eau 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.
- 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.
- 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.
- 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.
- Methyl Gluceth-20 humectant
- Methyl Gluceth-20 is a sugar-derived humectant. It holds water in the outer layer of skin and gives a smooth, cushioned slip that plain glycerin does not.
- 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.
- Diethoxyethyl Succinate solvent
- Diethoxyethyl Succinate is a solvent that helps water-resistant actives spread and sink in evenly. It also leaves a light, silky feel.
- Castor Oil/Ipdi Copolymer film former
- A polymer built from castor oil. It forms a flexible, glossy film, so it is used in lip and long-wear formulas for shine and staying power.
- 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.
- 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.
- Sodium Acrylic Acid/Ma Copolymer thickener
- An acrylic copolymer used to thicken water into a gel and to hold an emulsion stable.
47 more explained
- 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.
- 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.
- Benzotriazolyl Dodecyl P-Cresol antioxidant
- A light stabiliser. Its job is to keep the formula itself from degrading in light, so it is a product-stability ingredient rather than one aimed at skin.
- Tocopherol antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
- 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.
- Pullulan film former
- Pullulan is a fermentation-derived polysaccharide that dries to a tight film, which is why it produces a temporary, visible tightening feel on the skin.
- Sodium Phytate chelator
- Sodium Phytate is a rice-derived chelator used in place of EDTA. It ties up trace metals so the formula stays stable and its colour and scent hold.
- 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.
- Hibiscus Sabdariffa Flower Extract plant extract
- Roselle hibiscus extract, deep red from anthocyanins and naturally acidic. It carries plant acids and is used as an antioxidant extract.
- Gardenia Florida Fruit Extract plant extract
- Gardenia Fruit Extract is the traditional East Asian yellow dye plant. In skincare it is used as an antioxidant extract, and it can tint a formula.
- Caprylyl Glycol preservative booster
- Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
- Nicotinamide Adenine Dinucleotide active
- Nicotinamide Adenine Dinucleotide, usually written NAD, is a coenzyme every living cell carries, built from vitamin B3. In a formula it is used as a conditioning active at very low levels.
- Alcohol solvent
- Alcohol here means ethanol. It dissolves ingredients water cannot, evaporates fast so a formula sets quickly and does not feel heavy, and thins texture. In quantity it can leave dry or reactive skin feeling tight, which is why many Korean formulas avoid it and some deliberately use it for a fast, weightless finish.
- Ectoin humectant
- Ectoin is a small molecule that microbes in salt flats and hot springs make to survive extreme conditions. In skincare it holds water tightly around itself, which is why it appears in formulas aimed at reactive, easily dehydrated skin.
- Nicotinamide Mononucleotide active
- Nicotinamide Mononucleotide is a nucleotide built from vitamin B3 and a sugar phosphate. Korean formulas use it as a conditioning active, usually alongside niacinamide itself.
- Cyanocobalamin vitamin
- 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.
- Dextrin thickener
- Dextrin is a starch fragment used to thicken and to give a formula a light, powdery finish. It is also a common carrier for powdered extracts.
- Tris(Tetramethylhydroxypiperidinol) Citrate antioxidant
- A hindered-amine antioxidant used to keep a formula from breaking down in light and air. It works on the product rather than on skin.
- Octyldodecanol emollient
- Octyldodecanol is a branched fatty alcohol used as an emollient and as a solvent for pigments and mineral powders. It thickens slightly and leaves a soft finish.
- 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.
- Jasminum Officinale (Jasmine) Extract plant extract
- Jasmine extract, from the flower. It is used as a conditioning plant extract and contributes its own scent.
- Salix Alba (Willow) Bark Extract plant extract
- Willow Bark Extract carries salicin, the plant compound salicylic acid is related to. The two are not interchangeable: willow bark is a mild clarifying extract, not a BHA exfoliant at the levels used in cosmetics.
- Solanum Melongena (Eggplant) Fruit Extract plant extract
- Eggplant Fruit Extract carries nasunin, the antioxidant pigment in aubergine skin. It is used as an antioxidant plant extract.
- Ethylhexyl Palmitate emollient
- Ethylhexyl Palmitate is a palm-derived ester used as a light emollient and a solvent for pigment. It gives a smooth, non-greasy slip.
- Pentaerythrityl Tetraisostearate emollient
- A thick, cushioned ester that gives lip and balm formulas their gloss and their cling. It is heavy enough to stay where it is put.
- 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.
- 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.
- Polyglutamic Acid humectant
- Polyglutamic Acid comes from fermented soy and holds several times more water than hyaluronic acid for its weight. It forms a light film on the surface, so it is often layered with hyaluronic rather than replacing it.
- Citric Acid pH adjuster
- Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
- Fucus Vesiculosus Extract plant extract
- Bladderwrack extract, a brown seaweed named for the air bladders that float it. It carries fucoidan and alginates and is used as a hydrating marine extract.
- Heptasodium Hexacarboxymethyl Dipeptide-12 peptide
- A two-amino-acid peptide with carboxymethyl groups added, which makes it strongly water soluble. It is used for the look of uneven tone.
- Prunella Vulgaris Extract plant extract
- Selfheal extract, a mint-family herb long used in East Asian practice. It carries rosmarinic acid and is used as a conditioning antioxidant extract.
- Resveratrol antioxidant
- Resveratrol is an antioxidant from grape skin and Japanese knotweed. It is used for the look of dullness and is often paired with ferulic acid, which keeps it stable.
- Trihydroxystearin thickener
- A castor-derived wax used to thicken oils and stop pigments settling. It builds structure in an anhydrous formula without making it hard.
- Diospyros Kaki Leaf Extract plant extract
- Diospyros Kaki is the persimmon tree. Its leaf extract carries tannins and vitamin C and is used as an antioxidant extract.
- Vitis Vinifera (Grape) Fruit Extract plant extract
- Grape Fruit Extract carries polyphenols and fruit acids. It is used as an antioxidant plant extract.
- Carthamus Tinctorius (Safflower) Flower Extract plant extract
- Safflower Flower Extract is a traditional East Asian dye and skincare plant. It is used as a conditioning antioxidant extract and can tint a formula.
- Coffea Arabica (Coffee) Seed Extract plant extract
- Coffee Seed Extract carries caffeine and chlorogenic acid. It is used as an antioxidant extract and, in eye and body formulas, for the look of puffiness.
- Polygonum Cuspidatum Root Extract plant extract
- Polygonum Cuspidatum is Japanese knotweed, the main commercial source of resveratrol. Its root extract is used as an antioxidant plant extract.
- Camellia Sinensis Leaf Extract plant extract
- Camellia Sinensis is the tea plant. Green tea leaf extract carries catechins, among the most studied plant antioxidants, and is used for the look of redness and oily shine.
- Castanea Crenata (Chestnut) Shell Extract plant extract
- Chestnut Shell Extract carries tannins and is used as an antioxidant plant extract, most often in formulas aimed at visible pores.
- Zanthoxylum Piperitum Fruit Extract plant extract
- Zanthoxylum Piperitum is Korean pepper. Its fruit extract is used as a conditioning plant extract and is often paired with pulsatilla and usnea in Korean formulas.
- Propylene Carbonate solvent
- A polar solvent used mainly with clays: it swells montmorillonite and hectorite so they thicken an oil phase. It also thins heavy pigment pastes.
- Stearalkonium Hectorite thickener
- Stearalkonium Hectorite is a modified clay that gels oils and keeps powders evenly suspended in an anhydrous formula.
- 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.
- Palmitoyl Hexapeptide-12 peptide
- Palmitoyl Hexapeptide-12 is a fatted six-amino-acid peptide used for the look of firmness, usually as part of a multi-peptide blend.
- Glucomannan thickener
- Glucomannan is a konjac root polysaccharide. It thickens, holds a great deal of water and leaves a smooth, cushioned film.

How to use
- Apply it after your toner, while the face is still slightly damp, so a thin layer spreads without dragging.
- Three or four drops cover the whole face; press it in with the flats of the fingers rather than rubbing.
- Follow with a moisturizer within a minute so the thin layer has something holding it down.
- Do not stack it under a second serum doing the same job, since more layers is not the same as more result.
Worth knowing
- Introduce any new active serum gradually, a few nights a week at first, rather than daily right away.
- Follow an exfoliating or retinoid-containing serum with daytime sun protection the next morning as a separate step.
