How it works
The Miracle Vitamin C Serum is a 40ml serum, used after toner and before moisturizer, morning and evening. The antioxidant it is built around is Ascorbic Acid, named twenty-seventh on its own ingredient list. The same list carries Niacinamide, Adenosine and Biotin, so the antioxidant is not the only thing on it worth naming. How much of the Ascorbic Acid stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum DEWYTREE sells in Korea, Ascorbic Acid and all.

- Biotin and Folic Acid on the same list, vitamins
- Pyridoxine and Cyanocobalamin further down the same list
- Riboflavin and Thiamine HCl further down the same list
- Ascorbic Acid named twenty-seventh on the manufacturer list printed on this page
Inside the formula
Inside the formula
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 Ascorbic Acid and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Ascorbic Acid and all. We match this serum 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 Ascorbic Acid?
Niacinamide, Adenosine and Biotin. The order they are printed in on this serum's panel is the order on the box, so you can see where Ascorbic Acid sits relative to them. Further down the same panel: Folic Acid, Pyridoxine and Cyanocobalamin.

Ingredient list read from dewytree.com on 10 September 2026.
48 of 50 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Hippophae Rhamnoides (Sea Buckthorn) Fruit Extract (4,500 ppm) plant extract
- Sea Buckthorn Fruit Extract is high in vitamin C and carotenoids, which give it a strong orange colour. It is used as an antioxidant extract.
- PPG-13-Decyltetradeceth-24 emulsifier
- PPG-13-Decyltetradeceth-24 is a solubiliser used to hold oils and fragrance in a clear water-based formula.
- 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.
- Melia Azadirachta (Neem) 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.
36 more explained
- Ocimum Sanctum (Holy Basil) 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.
- 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.
- 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.
- 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.
- 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.
- Rosmarinus Officinalis (Rosemary) Leaf Oil fragrance component
- Rosemary Leaf Oil is an essential oil carrying camphor and cineole. It scents a formula and is a stronger aromatic than most.
- 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.
- Glyceryl Acrylate/Acrylic Acid Copolymer film former
- This is a polymer that forms a moisture-holding film on the surface, usually supplied with glycerin and propylene glycol as a hydrating complex.
- 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.
- PVM/MA Copolymer film former
- PVM/MA Copolymer is a film-forming polymer used to hold a formula in place and, in a mask, to give the peel-off film its strength.
- 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.
- Theobroma Cacao (Cocoa) Extract plant extract
- Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint.
- 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.
- Ascorbic Acid (10 ppm) 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.
- 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.
- 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.
- Terminalia Ferdinandiana (Kakadu Plum) Fruit Extract plant extract
- Kakadu plum fruit extract, the highest natural source of vitamin C known. It is used as a plant antioxidant.
- Citrus Junos Fruit Extract plant extract
- Yuja fruit extract, the Korean citrus preserved as yuja tea. It carries vitamin C, fruit acids and flavonoids.
- 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.
- 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.
- 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.
- Polyglyceryl-10 Stearate emulsifier
- Polyglyceryl-10 Stearate is a mild sugar-derived emulsifier that holds oil into water and thickens slightly.
- Lactococcus Ferment Extract ferment
- An extract of a lactococcus culture, one of the lactic acid bacteria used in cheesemaking. It supplies peptides and organic acids as a conditioning ferment.
- Bifida Ferment Extract ferment
- An extract of a bifidobacteria culture, the same organism behind bifida ferment lysate. It is used as a conditioning ferment.
- Lactobacillus Ferment Lysate ferment
- Lactobacillus Ferment Lysate is the ferment with the bacterial cells broken open, so their contents are in the formula too. It is a conditioning ferment used in barrier-focused products.
- Sodium Ascorbyl Phosphate antioxidant
- Sodium Ascorbyl Phosphate is a water-soluble, stable vitamin C salt. It works at near-neutral pH, so it appears in formulas aimed at skin that pure ascorbic acid leaves stinging.
- Hydroxypropyl Cyclodextrin solvent
- Hydroxypropyl Cyclodextrin is a ring-shaped sugar that traps an active molecule inside itself, keeping it stable and releasing it slowly. It is a delivery shell rather than an active.
- 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.
- Biotin vitamin
- Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
- 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.
- 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.
- Linoleic Acid fatty acid
- Linoleic Acid is an essential omega-6 fatty acid and the main fatty acid in sunflower, safflower and rosehip oil. In a formula it is a lipid that softens and sits in the outer layer.
- 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.
- Beta-Carotene antioxidant
- Beta-Carotene is an orange plant pigment and a vitamin A precursor. It is used as an antioxidant and it tints a formula, which is often why it is there.
- 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.

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.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Ascorbic Acid on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Ascorbic Acid rather than to three changes at once.
