How it works
This is a serum, so it is a small measured dose aimed at one concern rather than a layer for the whole routine. A few drops cover the whole face, and the finish it leaves is close to bare skin rather than glossy. Even tone is judged in a mirror, so what a cosmetic step changes is how uniform the surface looks and how evenly it reflects light. An ampoule is the same idea at a higher strength and a shorter course, while a serum is the everyday version of it. The result you can judge yourself is whether your tone looks more even in the same light over several weeks.
Key benefits
- Vita Niacinamide Dark Spot Serum 30ml is Round Lab's serum, sourced for the Korean market rather than reformulated for US shelves.
- Carries Niacinamide, which is the brightening, barrier-supporting workhorse behind most Korean tone-evening formulas, and it layers easily under sunscreen and makeup.
- Carries Panthenol, which is provitamin B5, a humectant that helps a formula feel less tight after it dries down.
- Carries Centella Asiatica Extract, which is a full cica leaf extract Korean formulators reach for on stressed, easily flushed skin.
- Ships with the Korean-market barcode and batch code intact, the same box sold on Korean shelves rather than a US repack.
- Suited to shoppers targeting redness and easily-stressed skin.
Inside the formula
Inside the formula
What is Vita Niacinamide Dark Spot Serum 30ml?
It is a targeted serum from Round Lab, made for anyone bothered by uneven tone and by the look of the dark marks a breakout leaves behind. It goes on after your toner and before your moisturiser, so it reaches clean skin rather than sitting on a cream. The result you can judge yourself is whether your tone looks more even in the same light over several weeks.
Where does Vita Niacinamide Dark Spot Serum 30ml go in my routine?
It goes on after your toner and before your moisturiser, so it reaches clean skin rather than sitting on a cream. In practice: Press three or four drops over the face after your toner, then follow with your moisturiser once it has settled. Applying it out of that order is the usual reason a step seems to do nothing.
Is Vita Niacinamide Dark Spot Serum 30ml right for my skin type?
It is aimed at anyone bothered by uneven tone and by the look of the dark marks a breakout leaves behind. The skin types we would put first are normal skin, combination skin and dry skin. Tone work is slow work, so photograph the same area in the same light every fortnight rather than judging it in a different mirror each week.
Will this pill or roll up under a moisturiser?
Pilling usually comes from applying the next layer too soon or from using too much of this one. Give it thirty seconds to settle, use three or four drops rather than a pipette full, and press the moisturiser on rather than rubbing it in. If a specific sunscreen still rolls with it, change the order of those two steps before you blame either product.
Is this Vita Niacinamide Dark Spot Serum 30ml the authentic Korean-market formula?
Yes. We stock the Round Lab Korean-market formula rather than a version reformulated for US shelves. The bottle you open is the 30ml one sold on Korean shelves, with Korean-primary packaging and an intact barcode you can check yourself.

37 of 37 explained
- Hippophae Rhamnoides Water plant extract
- Hippophae Rhamnoides is sea buckthorn. Its water is used in place of plain water as a base and carries traces of the fruit's vitamins.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Hippophae Rhamnoides Fruit Extract 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.
25 more explained
- 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.
- 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.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener
- This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
- 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.
- 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.
- Portulaca Oleracea Extract plant extract
- Portulaca Oleracea is purslane. Its extract is unusually high in omega-3 fatty acids and antioxidants for a plant, and Korean formulas use it for the look of reddened, 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.
- 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.
- 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.
- 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.
- Chamomilla Recutita (Matricaria) Flower Extract plant extract
- Chamomile Flower Extract is one of the oldest ingredients in skincare, carrying bisabolol and chamazulene. It is used for the look of redness in formulas for reactive skin.
- 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.
- 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.
- Cyamopsis Tetragonoloba (Guar) Gum thickener
- Guar Gum is a seed polysaccharide that thickens and stabilises. It also leaves a conditioning film that makes skin feel smooth.
- Agar thickener
- Agar is a seaweed polysaccharide that sets into a firm gel. It is the gelling agent behind jelly masks and thick sleeping packs.
- 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.
- 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.
- Ficus Carica (Fig) Fruit Extract plant extract
- Fig Fruit Extract carries fruit sugars, mild acids and a protein-digesting enzyme. It is used as a hydrating extract with a light smoothing effect.
- Hydroxydecyl Ubiquinone antioxidant
- Hydroxydecyl Ubiquinone is idebenone, a synthetic relative of coenzyme Q10 made to be more stable and more soluble than the natural molecule.
- 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.
- 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.
- 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.
- 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.
- Helianthus Annuus (Sunflower) Seed Oil emollient
- Sunflower Seed Oil is high in linoleic acid, the fatty acid dry and blemish-prone skin is often short of. It is a light, non-fragrant emollient and one of the better tolerated plant oils.
- Xanthophylls antioxidant
- Xanthophyll is the yellow carotenoid family lutein belongs to, found in marigold and leafy greens. It is used as a plant antioxidant and tints a formula yellow.

How to use
- Use it after cleansing and toning, while the surface is still slightly damp.
- Press three or four drops over the face and neck rather than rubbing them in.
- Wait until it feels dry to the touch, then apply your moisturiser over the top.
- Do not apply it over a cream or an oil, since a light serum cannot get through a finished occlusive layer.
Worth knowing
- Patch test on a small area first, since tone focused steps are the ones most likely to sting on reactive skin.
- Give it several weeks of consistent use before you judge it, and change one thing at a time in your routine.
