How it works
The AC Deep Blemish Calming Ampoule is a 60ml ampoule, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named second on its own ingredient list. The same list carries Adenosine, Methyl Diisopropyl Propionamide and Asiaticoside, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the ampoule format rather than by the list alone. This is the Original Korean Formula, the ampoule DEWYTREE sells in Korea, Niacinamide and all.
Key benefits
- Niacinamide, the active this ampoule is built around
- Adenosine, Methyl Diisopropyl Propionamide, Asiaticoside and Madecassic Acid on the same list, actives
- Asiatic Acid and Papain further down the same list
- Niacin and Riboflavin further down the same list
- Niacinamide named second on the manufacturer list printed on this page
- Original Korean Formula, the ampoule sold on Korean shelves
How to use
- Use this serum AM and/or PM, as the serum step, after toner or essence and before moisturizer. Pat or smooth it on rather than rubbing, and give it a moment to settle before layering the next step.
Where does this ampoule go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than an ampoule goes on before it, and anything richer goes on after. 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 Niacinamide and not three changes at once.
Is this the Korean-market ampoule or a US version?
The Korean-market one, Niacinamide and all. We match this ampoule 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 Niacinamide?
Adenosine, Methyl Diisopropyl Propionamide and Asiaticoside. The order they are printed in on this ampoule's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Madecassic Acid, Asiatic Acid and Papain.

63 of 63 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.
- 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.
- 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.
- 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.
- 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.
- Isopentyldiol solvent
- Isopentyldiol is a glycol used as a light solvent and humectant. It thins a formula, keeps extracts dissolved and leaves a dry finish.
- 2,3-Butanediol humectant
- 2,3-Butanediol is a fermentation-derived glycol. It hydrates and, like the other longer glycols, makes a formula harder for microbes to grow in.
- 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.
- Polyglyceryl-10 Laurate emulsifier
- Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
- 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.
- 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.
51 more explained
- 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.
- 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.
- Saccharide Isomerate humectant
- A plant-sugar complex whose structure resembles the sugars already bound to the skin surface, so it stays through washing. It is used as a long-acting humectant.
- 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.
- 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.
- 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.
- 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.
- 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.
- Mentha Piperita (Peppermint) Oil fragrance
- Peppermint essential oil. Its menthol content is what produces the cool feeling, and it is a commonly declared fragrance material.
- 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.
- 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.
- Centella Asiatica Extract plant extract
- Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
- Betula Platyphylla Japonica Juice plant extract
- Betula Platyphylla Japonica Juice is Asian white birch sap, tapped in spring. It is over 98 percent water with trace minerals and sugars, and Korean formulas use it in place of plain water as a hydrating base.
- 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.
- Sodium Citrate pH adjuster
- Sodium Citrate is the salt of citric acid, used as a buffer: it holds a formula at a steady pH rather than pushing it in one direction. It is also a mild chelator.
- 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.
- Citrus Aurantifolia (Lime) Fruit Extract plant extract
- Lime fruit extract, carrying citric acid, sugars and citrus flavonoids. It is the water based fruit extract rather than the peel oil.
- Citrus Limon (Lemon) Fruit Extract plant extract
- Lemon fruit extract, carrying citric acid, sugars and flavonoids. It is the water-based fruit extract rather than the peel oil, so it brings the fruit acids without the aromatic terpenes.
- Malus Domestica Fruit Extract plant extract
- Apple fruit extract, carrying malic acid, sugars and polyphenols. It is used as a conditioning extract and a mild source of fruit acid.
- Citrus Aurantium Dulcis (Orange) Fruit Extract plant extract
- Sweet orange fruit extract, carrying fruit acids, sugars and flavonoids. It is used as a conditioning extract.
- Vitis Vinifera (Grape) Fruit Extract plant extract
- Grape Fruit Extract carries polyphenols and fruit acids. It is used as an antioxidant plant extract.
- 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.
- Diospyros Kaki Fruit Extract plant extract
- Persimmon fruit extract. It carries tannins, sugars and vitamin C, and it is used as an antioxidant, conditioning extract.
- 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.
- Laminaria Japonica Extract plant extract
- Laminaria Japonica is kombu kelp. Its extract carries alginates, minerals and iodine, and it is used as a hydrating, mineral-rich ingredient.
- 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.
- Oryza Sativa (Rice) Extract plant extract
- Rice Extract is the anchor of the Korean rice-skincare category. It carries starches, amino acids and ferulic acid, and it is used for the look of dullness and for a soft, blurred finish.
- Artemisia Princeps Leaf Extract plant extract
- Artemisia Princeps is Korean mugwort, one of the country's oldest skincare and bathing plants. Its leaf extract is used for the look of reddened, reactive skin, and it is the ingredient behind the mugwort category.
- Aloe Barbadensis Leaf Extract plant extract
- Aloe Leaf Extract is mostly water with polysaccharides, amino acids and mild plant acids. It hydrates and leaves a light, cooling film, which is why it is the default after-sun ingredient.
- Viola Mandshurica Flower Extract plant extract
- Viola Mandshurica is Manchurian violet. Its flower extract is used as a conditioning plant extract.
- Dioscorea Japonica Root Extract plant extract
- Dioscorea Japonica is Japanese wild yam, whose root is naturally slippery with mucilage. Its extract hydrates and leaves a cushioned feel.
- Papain exfoliant
- Papain is a protein-cutting enzyme from papaya. Enzyme exfoliants act on protein rather than on the bonds an acid targets, and they need water to work, which is why they suit powder washes.
- Asiaticoside active
- Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
- Madecassic Acid active
- Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.
- Asiatic Acid active
- Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
- 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.
- Mentha Piperita (Peppermint) Extract plant extract
- Peppermint leaf extract, the water-based extract rather than the essential oil, so it carries far less menthol. It is used as a refreshing herbal extract.
- Phytosterols emollient
- Phytosterols are plant sterols, structurally close to the cholesterol in skin's own lipid layer. They soften skin and help the oil phase of a formula hold together.
- Niacin vitamin
- Niacin is the acid form of vitamin B3. It is the same vitamin as niacinamide in a different chemical form, and it is used at very low levels as a conditioning vitamin.
- Riboflavin vitamin
- Riboflavin is vitamin B2, and it is a strong yellow, so a formula carrying it often has a colour nobody added on purpose.
- Biotin vitamin
- Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
- 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.
- 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.
- Ascorbic Acid antioxidant
- Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone.
- Carnitine amino acid
- Carnitine is an amino acid derivative the body uses to move fatty acids inside cells. In a formula it is a conditioning, water-holding ingredient.
- Calcium Pantothenate vitamin
- Calcium Pantothenate is the calcium salt of pantothenic acid, vitamin B5. It is the salt form of the same vitamin panthenol converts to, and it hydrates and conditions.
- Thiamine HCL vitamin
- Thiamine is vitamin B1, supplied as its hydrochloride salt so it dissolves in water. It is a conditioning vitamin and usually appears as part of a B-complex.
- 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.
- Folic Acid vitamin
- Folic Acid is vitamin B9. It is used in a formula as a conditioning vitamin, usually as part of a B-complex blend.
- Pyridoxine vitamin
- Pyridoxine is vitamin B6. In a formula it is a conditioning vitamin, most often in B-complex blends and scalp products.
