- Tocopheryl Acetate and Tocopherol further down the same list
- Niacinamide named third on the manufacturer list printed on this page
Key actives
3Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this serum's own ingredient list it is named third.
9Arbutinactive
Arbutin is the naturally occurring form of the same compound, from bearberry and related plants, used for the look of uneven tone. The alpha isomer is the more stable of the two. It is named ninth on this serum's list, alongside Niacinamide.
37Allantoinactive
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. The panel names it thirty-seventh on this serum's list, beside Niacinamide.
39Adenosineactive
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. It is named thirty-ninth on this serum's list, alongside Niacinamide.
42Dipotassium Glycyrrhizateactive
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. The panel names it forty-second on this serum's list, beside Niacinamide.

Where each key active sits on the declared ingredient list, by entry number. Position is proportion: the further forward, the larger its share.
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum 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.
Does this serum contain fragrance?
Yes. The ingredient list names Limonene and Linalool. They sit on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this serum is not the one.
What else is on the list besides Niacinamide?
Arbutin, Allantoin and Adenosine. The order they are printed in on this serum's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Dipotassium Glycyrrhizate, Madecassoside and Asiaticoside.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

Ingredient list read from inkeedecoder.com on 10 September 2026.
50 of 52 explained
- Citrus Tangerina (Tangerine) Extract plant extract
- Tangerine extract, carrying citrus flavonoids, sugars and a little citric acid. It is used as a conditioning antioxidant botanical.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Arbutin active
- Arbutin is the naturally occurring form of the same compound, from bearberry and related plants, used for the look of uneven tone. The alpha isomer is the more stable of the two.
- Chondrus Crispus Extract plant extract
- Chondrus Crispus is Irish moss, a red seaweed. It is loaded with carrageenan, so it hydrates and thickens at once, and it leaves a cushioned, slippery film.
- Saccharum Officinarum (Sugarcane) Extract plant extract
- Sugarcane Extract carries natural glycolic acid and sugars. In cosmetics it is used as a humectant; the acid content is far too low to work as an exfoliant.
- Hydrolyzed Jojoba Esters emollient
- Jojoba Esters are jojoba wax rebuilt into a softer, meltable form. They condition skin and give body to balms without the heaviness of a butter.
38 more explained
- 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.
- Citrus Aurantium Bergamia (Bergamot) Fruit Oil fragrance component
- Bergamot Fruit Oil is a citrus essential oil and the top note of eau de cologne. It scents a formula; citrus oils are the aromatic class most likely to bother reactive skin.
- 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.
- Ocimum Sanctum Leaf Extract plant extract
- Ocimum Sanctum is holy basil, or tulsi. Its leaf extract carries plant antioxidants and is used in formulas built for the look of stressed, reactive skin.
- Curcuma Longa (Turmeric) Root Extract plant extract
- Turmeric Root Extract carries curcuminoids, well studied plant antioxidants. It is used for the look of dullness and uneven tone, and it tints a formula faintly yellow.
- 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.
- Lavandula Angustifolia (Lavender) Oil fragrance component
- Lavender Oil is an essential oil carrying linalool and linalyl acetate. It scents a formula, and linalool is one of the fragrance components EU labelling requires to be named separately.
- Citrus Limon (Lemon) Peel Oil fragrance
- Cold-pressed lemon peel oil. Citrus peel oils carry limonene and can make skin more sensitive to sunlight, which is why leave-on formulas use them sparingly.
- Cananga Odorata Flower Oil fragrance
- Ylang ylang oil, a heavy sweet floral essential oil. It is among the most commonly declared natural fragrance materials.
- Citrus Aurantium Dulcis (Orange) Peel Oil fragrance component
- Sweet Orange Peel Oil is a citrus essential oil carrying limonene. It scents a formula, and limonene is one of the components EU labelling names separately.
- Eucalyptus Globulus Leaf Extract plant extract
- Eucalyptus leaf extract, the water-based extract rather than the essential oil. It carries tannins and flavonoids with only a trace of the aroma.
- Glycyrrhiza Uralensis (Licorice) Root Extract plant extract
- Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives.
- Anthemis Nobilis Flower Extract plant extract
- Roman chamomile flower extract. It carries flavonoids and is one of the classic plant ingredients in formulas aimed at the look of reddened skin.
- 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.
- 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.
- Rosmarinus Officinalis (Rosemary) Leaf Extract plant extract
- Rosemary Leaf Extract carries rosmarinic and carnosic acids, both effective antioxidants. It is often there to keep the oils in a formula from going rancid.
- 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.
- 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.
- 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.
- Choleth-24 emulsifier
- Choleth-24 is a cholesterol-derived solubiliser. It keeps oils and oil-soluble actives dissolved in a clear formula.
- 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.
- 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.
- 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.
- 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.
- 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 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.
- Ascorbyl Glucoside antioxidant
- Ascorbyl Glucoside is vitamin C bound to glucose, which keeps it stable until enzymes in skin release it. It is a mild, slow-release route to a vitamin C formula.
- Dipotassium Glycyrrhizate active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- 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.
- Madecassoside active
- Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams.
- Maltodextrin film former
- Maltodextrin is a starch-derived sugar chain used to carry powdered extracts and to form a light film. It also gives a soft, smoothing feel.
- 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.
- 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.
- 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.
- 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.
- Limonene fragrance component
- Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
- Linalool fragrance component
- Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.

How it works
The Green Tangerine Vita C Dark Spot Care Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named third on its own ingredient list. The same list carries Arbutin, Allantoin and Adenosine, 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 serum format rather than by the list alone. goodal sells this Niacinamide serum in Korea, and this is that version.
How to use
- Apply a few drops to clean, toned skin morning and night, then follow with cream to seal it in.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- This list names Limonene and Linalool, so skip it if fragrance components are something you avoid.

What professionals say
What professionals say
What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Arbutin works to inhibit tyrosinase, an enzyme present in melanocytes, the pigment-producing cells in the skin. This results in less pigment, dark spots and skin lightening.
Tiffany Jow Libby, MDBoard-certified dermatologist, mindbodygreen Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
