How to use
- Use the Yuja Niacin Brightening All-In-One Cleanser as your first step, morning and evening, on skin wet with lukewarm water.
- A coin-sized amount, worked between wet palms for twenty to thirty seconds, then massaged over the face in small circles.
- Rinse and tone while skin is still damp. Everything after this lands on bare skin, so it decides what the rest of the routine is working with.
- Twice a day, every day. Do not stretch the massage past a minute or finish with hot water; both leave the surface feeling tight rather than clean.
Does this product contain added fragrance?
Yes. The ingredient list for SOME BY MI Yuja Niacin Brightening All-In-One Cleanser 100ml includes Fragrance. That is the label name for an added scent blend, whose individual components are not itemised beyond any allergens the label declares separately. The full list is printed in the Ingredients section of this page.
Are any declarable fragrance allergens listed?
Yes. Limonene and Linalool appear on the ingredient list for SOME BY MI Yuja Niacin Brightening All-In-One Cleanser 100ml. These belong to the 26 fragrance components that EU cosmetic labelling requires to be named individually rather than folded into a fragrance entry.
Does this product contain denatured or SD alcohol?
No. The ingredient list for SOME BY MI Yuja Niacin Brightening All-In-One Cleanser 100ml names no denatured alcohol, SD alcohol or ethanol. Fatty alcohols such as cetyl and cetearyl alcohol are a different class of ingredient, used as emollients and thickeners, and are not counted here.

Ingredient list read from somebymi.co.kr on 13 September 2026.
49 of 49 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.
- Sodium C14-16 Olefin Sulfonate surfactant
- A strong anionic surfactant that foams heavily. It is a sulfate alternative in name but not in strength, and it is more common in shampoos than in facial cleansers.
- Citrus Junos Fruit Extract plant extract
- Yuja fruit extract, the Korean citrus preserved as yuja tea. It carries vitamin C, fruit acids and flavonoids.
- Cocamidopropyl Betaine surfactant
- Cocamidopropyl Betaine is a coconut-derived secondary surfactant. Its job is to boost foam and soften the harshness of the main cleanser rather than to clean on its own.
- Acrylates Copolymer film former
- Acrylates Copolymer is a synthetic polymer that forms a film as the water leaves. It holds a formula in place, controls shine and helps a texture stay put.
- 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.
- Gluconolactone exfoliant
- Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
- Tetradecene emollient
- A light hydrocarbon used as a spreading agent, mostly in the polymer blends that thicken a lotion.
- Sodium Chloride thickener
- Sodium Chloride is salt. In a cleanser it thickens the liquid; in a mask or essence it balances the mineral content of the water phase. It has no active role.
- 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.
- Hexadecene emollient
- A light hydrocarbon used as a carrier and spreading agent within a thickener system.
- 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.
37 more explained
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Succinic Acid active
- Succinic Acid is a small organic acid used for the look of blemish-prone skin and as a pH adjuster. It is far milder than an AHA at the levels used here.
- 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 Crosspolymer humectant
- Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
- Eriobotrya Japonica Leaf Extract plant extract
- Eriobotrya Japonica is loquat. Its leaf extract carries triterpenes and is used as a conditioning antioxidant extract.
- 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.
- Hydrolyzed Glycosaminoglycans humectant
- Hydrolyzed Glycosaminoglycans are short fragments of the sugar chains that sit between cells in skin, hyaluronic acid among them. They act as humectants and give a cushioned feel.
- Polyglyceryl-10 Stearate emulsifier
- Polyglyceryl-10 Stearate is a mild sugar-derived emulsifier that holds oil into water and thickens slightly.
- 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.
- Mentha Viridis (spearmint) Extract plant extract
- Spearmint Extract carries aromatic plant compounds and gives a faint cooling sensation. It also scents a formula.
- Sodium Acetylated Hyaluronate humectant
- Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
- Benzyl Glycol preservative booster
- Benzyl Glycol is a solvent that also makes a formula less hospitable to microbes, so it appears in preservative blends built without parabens.
- 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.
- 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.
- Biotin vitamin
- Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
- Pyridoxine vitamin
- Pyridoxine is vitamin B6. In a formula it is a conditioning vitamin, most often in B-complex blends and scalp products.
- 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.
- 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.
- Raspberry Ketone fragrance component
- Raspberry Ketone is the compound that gives raspberries their smell. On a list it is an aromatic ingredient rather than a functional one.
- 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.
- 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.
- 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.
- Inositol humectant
- Inositol is a sugar-like compound found in the body. In skincare it is a humectant that also helps a formula feel conditioning rather than merely wet.
- 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.
- 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.
- Fragrance fragrance
- Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
- 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.
