Key actives
5Niacinamide
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.
22Adenosine
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.
30Thyme Extract
Thyme leaf extract, carrying the phenols thymol and carvacrol along with rosmarinic acid. It is used as an antioxidant herbal extract.
31Salvia Officinalis Extract
Sage extract, carrying rosmarinic acid and tannins. It is used as an antioxidant, astringent-feeling plant extract.

What is Aroma Nut Slim Fit Body GuaSha Serum used for?
It is a serum from Nutseline, a concentrated, fast-absorbing liquid. Nutseline is a Korean nut-and-plant-oil skincare label, formulating its balms and creams around shea, coconut and other seed oils rather than gel humectants alone. It is meant to be used as one step in a routine rather than a stand-alone treatment, and it ships here in the same Korean-market formula sold at retail in Seoul.
How do I use Aroma Nut Slim Fit Body GuaSha Serum?
Apply a few drops to clean, toned skin morning and night, then follow with cream to seal it in. Give it a few uses before judging the result, since a single application rarely shows the full effect a serum is built to deliver over a routine.
Is this the same formula sold in Korea?
Yes. What we carry is the identical Korean-market version Nutseline sells at Olive Young and other Seoul retailers, carrying its original packaging, Korean-market barcode, and batch code rather than a swapped-in export version.
How is this different from buying Nutseline on Amazon or a general beauty marketplace?
The difference is the formula itself: this is what Nutseline sells at retail in Seoul, not a substitute made for a different market.
Can I use this with other actives in my routine?
Yes, a serum like this is built to sit alongside the rest of a layered routine rather than replace it. Introduce it on its own for the first few uses so that if anything in your routine causes a reaction, this step is easy to rule in or out.

Ingredient list read from nutseline.com on 30 August 2026.
32 of 46 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.
- 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.
- 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.
- 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.
- 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.
- Shea Butter emollient
- Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
- Polyglyceryl-6 Stearate emulsifier
- Polyglyceryl-6 Stearate is a mild plant-derived emulsifier for oil-in-water creams.
- 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.
- Macadamia Seed Oil emollient
- Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin.
- 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.
- 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.
- Potassium Cetyl Phosphate emulsifier
- Potassium Cetyl Phosphate is an emulsifier prized for keeping powdered ingredients evenly suspended, which is why tinted and mineral-powder textures use it.
20 more explained
- Polyglyceryl-6 Behenate emulsifier
- A polyglycerin ester with a long fatty chain. It emulsifies and thickens at the same time, which is how a cream gets body without wax.
- 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.
- 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.
- 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 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.
- Thyme Extract plant extract
- Thyme leaf extract, carrying the phenols thymol and carvacrol along with rosmarinic acid. It is used as an antioxidant herbal extract.
- Salvia Officinalis Extract plant extract
- Sage extract, carrying rosmarinic acid and tannins. It is used as an antioxidant, astringent-feeling plant extract.
- Anemarrhena Asphodeloides Root Extract plant extract
- Anemarrhena Asphodeloides is a root used in Korean traditional practice. Its extract is used as a conditioning plant extract.
- 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.
- Quercetin antioxidant
- Quercetin is one of the most widespread plant flavonoids, found in onion skin, apple peel and tea. It is a plant antioxidant and is yellow, so it tints a formula.
- Caffeine active
- Caffeine constricts small blood vessels near the surface, which is why eye products use it for the look of puffiness and shadow. It is water soluble and works only while it is on the skin.
- Sweet Almond Oil emollient
- Sweet almond oil, one of the oldest cosmetic oils. It is high in oleic acid, which makes it richer and slower to absorb than the linoleic oils.
- Coffea Arabica Seed Extract plant extract
- Coffee Seed Extract carries caffeine and chlorogenic acid. It is used as an antioxidant extract and, in eye and body formulas, for the look of puffiness.
- Hydrolyzed Extensin protein
- Extensin is a structural glycoprotein from plant cell walls. Hydrolysed, it is cut into fragments small enough to dissolve, and it works as a water-holding film on the surface.
- Citral fragrance component
- Citral is a sharp lemon aromatic found in lemongrass and citrus oils. It is one of the 26 fragrance components EU labelling requires to be named.
- Geraniol fragrance component
- Geraniol is a rose-scented aromatic found in geranium and citronella oils. It is one of the 26 declarable fragrance components.
- 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.
- Citronellol fragrance component
- Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
- 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.

How it works
Niacinamide leads the ingredient panel on this serum. 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. On this panel it sits alongside Adenosine, Thyme Extract and Salvia Officinalis Extract. 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.
