How it works
Sodium Ascorbyl Phosphate leads the ingredient panel on this serum. 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. On this panel it sits alongside Niacinamide, Terminalia Ferdinandiana Fruit Extract and Brassica Oleracea Acephala Leaf Extract. 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.

Inside the formula
Inside the formula
What is Real Vitamin C Serum 32g, and who is it for?
It is a concentrated serum, used after toner and before moisturizer, for skin that wants a middle step beyond a basic routine. As with any new step, give it a fair, consistent trial of a week or two before you decide whether to keep it in your routine, and stop if you notice ongoing irritation rather than pushing through it.
Do I use this morning, night, or both?
Most people use a serum twice a day, though once a night is a reasonable way to start if you are new to an extra step. As with any new step, give it a fair, consistent trial of a week or two before you decide whether to keep it in your routine, and stop if you notice ongoing irritation rather than pushing through it.
Is this the same formula sold in Korea, or a version made for the US market?
This is the Korean-market formula, the same one sold on shelves in Korea rather than a version reformulated for US retail.
Can I use this if my skin runs sensitive?
This serum is formulated with skin types like normal or combination skin in mind, but any new product is worth a patch test first if your skin reacts easily. A short patch test on the inside of your arm or behind an ear before it goes on your face is worth doing, and that goes for sensitive skin most of all.
How long before I will know if this is right for my skin?
Give it a full week or two of consistent use before you judge, since a single use rarely tells you much either way. Watch for how skin feels and looks rather than for any specific number, and stop use if you notice ongoing irritation.

28 of 32 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Terminalia Ferdinandiana Fruit Extract plant extract
- Kakadu plum fruit extract, the highest natural source of vitamin C known. It is used as a plant antioxidant.
- Brassica Oleracea Acephala Leaf Extract plant extract
- Kale leaf extract, carrying carotenoids, vitamin C and glucosinolates. It is used as a plant antioxidant.
- 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.
- Octyldodeceth-16 emulsifier
- An ethoxylated branched fatty alcohol. It emulsifies and also gives a formula a soft, cushioned slip.
16 more explained
- 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.
- 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.
- Sodium Metabisulfite antioxidant
- Sodium Metabisulfite is a sulfite salt used to stop a formula oxidising and browning. It is the ingredient that keeps a vitamin C or plant-extract formula from going amber.
- 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 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.
- 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.
- 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.
- 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.
- 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.
- Polyglyceryl-4 Caprate emulsifier
- Polyglyceryl-4 Caprate is a mild sugar-derived solubiliser used to dissolve fragrance and oil into watery formulas.
- 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.
- Coptis Japonica Root Extract plant extract
- Coptis Japonica is a traditional East Asian medicinal root, bright yellow from its berberine content. In skincare its extract is used for the look of congested, oily skin.
- Persea Gratissima (Avocado) Oil emollient
- Avocado oil, rich in oleic acid and plant sterols. It is one of the heavier plant oils, which suits dry skin and cleansing balms.
- 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.
- 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.
- 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.
