How it works
Medicube TXA Niacinamide Capsule Cream is a capsule cream built for the last step of a routine, over serum. Its ingredient list leads with Niacinamide, Adenosine, and Tranexamic Acid, so the formula's stated purpose lines up with what actually sits near the top of that list rather than with a single marketing ingredient buried further down. Niacinamide does the most work here as a tone and texture, and the remaining actives round out the texture and finish rather than compete for attention. Placed as the last step of a routine, over serum, it is meant to be used AM/PM rather than swapped freely between steps. Because this is the Korean-market version of the TXA Niacinamide Capsule Cream line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.
Key benefits
- Built around Niacinamide, positioned for tone and texture.
- Built around Adenosine, positioned for firming look.
- Built around Tranexamic Acid, positioned for tone.
- Formulated as a capsule cream for the last step of a routine, over serum.
- The Korean-market Medicube formula for TXA Niacinamide Capsule Cream, matching what Medicube sells in Korea rather than a US-reformulated line.
Inside the formula
Inside the formula
Medicube TXA Niacinamide Capsule Cream
What does the TXA Niacinamide Capsule Cream 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 TXA Niacinamide Capsule Cream?
Use this capsule cream as the last step of a routine, over serum. To apply, scoop a small amount, warm briefly between the fingertips as the capsules break down, and press over the face. Keep it to AM/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 TXA Niacinamide Capsule Cream the same formula sold in Korea, or a US version?
This TXA Niacinamide Capsule Cream 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 TXA Niacinamide Capsule Cream with other actives in my routine?
Yes, as long as it is used in its own step, the last step of a routine, over serum, 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 TXA Niacinamide Capsule Cream suited for?
It suits most skin types looking for last step of routine, over serum rather than a single acute problem. It comes in a 55g format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

Ingredient list read from incidecoder.com on 30 August 2026.
58 of 62 explained
- 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.
- Niacinamide (50,000ppm) 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
46 more explained
- 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.
- Cetearyl Alcohol fatty alcohol
- Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
- Cetearyl Olivate emulsifier
- Cetearyl Olivate is the water-loving half of the olive-derived emulsifier pair. With sorbitan olivate it builds emulsions whose lipid profile is close to skin's own.
- Sorbitan Olivate emulsifier
- Sorbitan Olivate is an olive-derived emulsifier, the oil-loving half of the pair sold as Olivem. It holds oil into water and leaves a light, non-waxy feel.
- C12-14 Alketh-12 emulsifier
- C12-14 Alketh-12 is a solubiliser used to keep oils and fragrance dissolved in a water-based formula.
- Ammonium Acryloyldimethyltaurate/VP Copolymer thickener
- This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.
- Simethicone silicone
- A silicone that breaks surface foam. In skincare its job is usually to stop a formula foaming during manufacture rather than anything it does on 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.
- Melia Azadirachta Flower Extract plant extract
- Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone skin.
- 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.
- Polyacrylate-13 thickener
- Polyacrylate-13 is a pre-neutralised thickener that gels instantly and holds an emulsion together, so a formula can be built without heat.
- 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.
- 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.
- Triethyl Citrate solvent
- Triethyl Citrate is a citric acid ester used as a light solvent and plasticiser. It keeps films flexible and helps hold fragrance in place.
- 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.
- Polyisobutene film former
- Polyisobutene is a synthetic polymer that forms a flexible, water-resistant film. It gives gloss and holds a formula in place, which is why it appears in lip products and long-wear textures.
- Glyceryl Stearate emulsifier
- Glyceryl Stearate is glycerin joined to stearic acid, and one of the most used emulsifiers in skincare. It holds oil and water together and thickens the result, and it softens skin at the same time.
- Hydrolyzed Sclerotium Gum polysaccharide
- A fungal polysaccharide cut into shorter pieces so it dissolves easily. It holds water and thickens without the stringiness of the whole gum.
- Tranexamic Acid active
- Tranexamic Acid is a synthetic amino acid derivative used for the look of stubborn discolouration and post-blemish marks. It is water soluble, stable and comfortable next to niacinamide, which is how it is usually paired.
- 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.
- Coccinia Indica Fruit Extract plant extract
- Coccinia Indica is ivy gourd. Its fruit extract is used as a conditioning, hydrating plant extract in Korean formulas.
- Corallina Officinalis Extract plant extract
- Corallina Officinalis is coral seaweed, which holds calcium and magnesium in its structure. Its extract is used as a mineral-rich conditioning ingredient.
- Polysorbate 20 emulsifier
- Polysorbate 20 is a solubiliser: it dissolves small amounts of oil or fragrance into a watery formula so nothing separates or floats.
- Sorbitan Isostearate emulsifier
- Sorbitan Isostearate is a mild emulsifier that holds water into oil, the direction a cleansing balm or an oil-based cream needs.
- Glutathione antioxidant
- Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it.
- Castanea Crenata 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.
- Citrus Junos Peel Extract plant extract
- Yuja peel extract. The peel is where the citrus flavonoids and aromatic oils concentrate, so it is stronger than the fruit extract.
- Betula Platyphylla Japonica Bark Extract plant extract
- Japanese white birch bark extract, carrying betulin and flavonoids. It is a different ingredient from the tapped birch sap on the same lists.
- Ricinus Communis Seed Oil emollient
- Castor Oil is thick, glossy and unusually good at dissolving pigment, which is why it dominates lip and cleansing-balm formulas. It is a heavy emollient.
- Bisabolol active
- Bisabolol is the main active fraction of chamomile oil, usually supplied from candeia wood. It is used for the look of redness in formulas for reactive skin, and it helps other ingredients absorb.
- Ferulic Acid antioxidant
- Ferulic Acid is a plant antioxidant from bran and seeds. Its main formulation job is stabilising vitamins C and E so a serum keeps working for longer, which is why the three appear together so often.
- Cymbopogon Citratus Leaf Oil fragrance component
- Lemongrass leaf oil, an essential oil rich in citral. It scents a formula and is one of the essential oils most likely to bother reactive skin.
- Illicium Verum Fruit/Seed Oil fragrance component
- Star anise oil, an essential oil dominated by anethole. It scents a formula strongly and is used in small amounts.
- 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.
- Hydrolyzed Hyaluronic Acid humectant
- Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
- 3-O-Ethyl Ascorbic Acid antioxidant
- 3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that skin converts to ascorbic acid. It survives in a formula far better than pure vitamin C and works at a gentler pH, so it suits skin that finds the pure acid uncomfortable.
- 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.
- Alpha-Arbutin active
- Alpha-Arbutin is a plant-derived compound, related to the sugar-bound form found in bearberry, used for the look of dark spots and uneven tone. It is stable in water and works at skin-friendly pH.
- 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.
- Hydroxypropyltrimonium Hyaluronate humectant
- Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
- 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.
- Sodium Acetylated Hyaluronate humectant
- Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
- Hyaluronic Acid humectant
- Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
- Sodium Hyaluronate Crosspolymer humectant
- Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
- Potassium Hyaluronate humectant
- Potassium Hyaluronate is another salt of hyaluronic acid, used for the same reason as the sodium form: it dissolves easily and holds a large amount of water in the outer layer of skin.

How to use
- AM and PM, after water-based layers and before sunscreen. The niacinamide and 3-O-ethyl ascorbic acid support a clearer-looking tone, so morning application pairs with a UV filter.
- Break the capsule into the gel base and mix until the texture unifies. Apply a pea-sized amount to the face. Press it over the skin, do not rub: rubbing drags the capsule oils into a film before they can integrate with the gel base.
- Start with three applications a week, then increase to daily as the skin adjusts to the niacinamide and alpha-arbutin.
- Seal it with a moisturizer if the skin feels dry, and always follow with sunscreen in the morning.
Worth knowing
- Patch test on the inner arm before the first full-face application, especially on skin that reacts easily to new products.
- Stop use and rinse off if stinging, burning, or new redness shows up rather than pushing through discomfort.
