ACSEN Sen Ampoule 35ml
Squalane is third and a run of esters follows it, so this 35ml ampoule is an oil-in-water emulsion rather than a watery one. Birch juice is sixteenth and propolis twenty-third.

How to use
- Use the ACSEN Sen Ampoule after toner and before moisturizer, morning and evening.
- Attach the syringe-style dropper without removing the silver seal or inner stopper. Apply 1 to 3 ml according to your skin's condition, dividing the amount into three applications and gently patting each layer into the skin. When the product level is low, remove the silver seal and inner stopper and replace them with the cap fitted with a nozzle.
- It sits between the toner and the moisturizer, and it is the layer most worth leaving alone for a minute before anything covers it.
- Twice a day, every day. Do not use it as a spot application on one area; an ampoule is a routine step, not a targeted dose.
Does this product contain added fragrance?
No. Neither fragrance nor parfum appears on the ingredient list for TROIAREUKE ACSEN Sen Ampoule 35ml. Those are the two names a cosmetic label uses for an added scent blend, so a formula carrying one would name it. The full list is printed in the Ingredients section of this page.
Does this product contain essential oils?
Yes. The ingredient list for TROIAREUKE ACSEN Sen Ampoule 35ml includes Pelargonium Graveolens Flower Oil. Aromatic plant oils are listed under their botanical name rather than as fragrance, so they are named separately from any fragrance or parfum entry.
Are any declarable fragrance allergens listed?
Yes. Citronellol and Geraniol appear on the ingredient list for TROIAREUKE ACSEN Sen Ampoule 35ml. 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 TROIAREUKE ACSEN Sen Ampoule 35ml 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.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

33 of 39 explained
- Water (Aqua) 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.
- Squalane emollient
- Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.
- 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.
- Propylene Glycol Dibenzoate emollient
- Propylene Glycol Dibenzoate is a light ester used as an emollient and solvent. It gives a dry, non-greasy slip and helps dissolve powders and pigments.
- 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.
- 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.
- Bis-Diglyceryl Polyacyladipate-2 emollient
- Bis-Diglyceryl Polyacyladipate-2 is a thick synthetic emollient built to mimic the lipids in skin's own surface. It is used in balms for a cushioned, sealing feel.
- C12-15 Alkyl Benzoate emollient
- C12-15 Alkyl Benzoate is a light ester emollient and solvent. It gives a silky finish, dissolves pigments and UV filters, and mildly discourages microbial growth.
- Diphenylsiloxy Phenyl Trimethicone silicone
- Diphenylsiloxy Phenyl Trimethicone is a high-shine silicone used where a formula needs gloss without stickiness.
- Arginine amino acid
- Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
- Cetyl Alcohol fatty alcohol
- Cetyl Alcohol is a waxy fatty alcohol from coconut or palm, unrelated to drying ethanol. It thickens creams, stabilises the emulsion and leaves skin feeling softer.
21 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.
- Ammonium Acryloyldimethyltaurate/VP Copolymer thickener
- This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.
- 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.
- 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.
- 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.
- 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.
- Pelargonium Graveolens Flower Oil fragrance component
- Pelargonium Graveolens is rose geranium. Its flower oil is an essential oil used to scent a formula, carrying citronellol and geraniol.
- Propolis Extract plant extract
- Propolis is the resin bees collect from tree buds and use to seal the hive. It is rich in flavonoids, carries a warm amber colour and scent, and is used for the look of dull, stressed skin. It is a bee product, so it is worth knowing about if you react to those.
- 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 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.
- 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.
- 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.
- 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.
- 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.
- Brassica Oleracea Italica (Broccoli) Extract plant extract
- Broccoli extract, carrying sulforaphane and vitamin C. It is used as a plant antioxidant.
- Brassica Oleracea Capitata (Cabbage) Leaf Extract plant extract
- Cabbage leaf extract. The leaf carries sulphur compounds, vitamin C and vitamin K, and the extract is used as a conditioning antioxidant botanical.
- Raphanus Sativus (Radish) Seed Extract plant extract
- Radish seed extract. It is used as a conditioning plant extract, and radish-root ferment filtrate from the same plant is a common natural preservative.
- 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.
- Citronellol fragrance component
- Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
- Geraniol fragrance component
- Geraniol is a rose-scented aromatic found in geranium and citronella oils. It is one of the 26 declarable fragrance components.
