How it works
The Eyelash Treatment Serum is a 6.5g serum, used after toner and before moisturizer, morning and evening. The active it is built around is Acetyl Glucosamine, named fourteenth on its own ingredient list. The same list carries Caffeine, Acetyl Hexapeptide-8 and Acetyl Octapeptide-3, so the active is not the only thing on it worth naming. How much of the Acetyl Glucosamine stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum BANILA CO sells in Korea, Acetyl Glucosamine and all.

Inside the formula
Inside the formula
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Acetyl Glucosamine and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Acetyl Glucosamine and all. We match this serum to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Acetyl Glucosamine?
Caffeine, Acetyl Hexapeptide-8 and Acetyl Octapeptide-3. The order they are printed in on this serum's panel is the order on the box, so you can see where Acetyl Glucosamine sits relative to them. Further down the same panel: Acetyl Tetrapeptide-2, Acetyl Tetrapeptide-3 and Acetyl Tetrapeptide-5.

Ingredient list read from banila.com on 30 August 2026.
36 of 36 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.
- 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.
- 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.
- 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.
- Pentylene Glycol humectant
- Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
- 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.
- Vincetoxicum Atratum Extract plant extract
- Baekmi, a traditional Korean herbal root extract. It is used as a conditioning plant extract, usually beside other Korean herbal ingredients.
- Althaea Rosea Flower Extract plant extract
- Althaea Rosea is hollyhock, a mallow relative rich in mucilage. Its flower extract hydrates and leaves a cushioned, slippery feel.
- 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.
- Ammonium Polyacryloyldimethyl Taurate thickener
- Ammonium Polyacryloyldimethyl Taurate is a polymer thickener that gels instantly and gives a light, silky body.
- 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.
- 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.
24 more explained
- Biotin vitamin
- Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
- Acetyl Glucosamine active
- Acetyl Glucosamine is the sugar unit hyaluronic acid is built from. It is used as a humectant and, at higher levels, for the look of uneven tone, often paired with niacinamide.
- 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.
- 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.
- Hydroxyacetophenone preservative booster
- Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
- 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.
- 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.
- 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.
- 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.
- Acetyl Hexapeptide-8 peptide
- Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable.
- Ascorbic Acid Polypeptide antioxidant
- Ascorbic Acid Polypeptide is vitamin C attached to a short protein chain to keep it stable in water. It is an antioxidant used for the look of dullness.
- Acetyl Octapeptide-3 peptide
- Acetyl Octapeptide-3 is an eight-amino-acid peptide used for the look of expression lines. It is usually paired with acetyl hexapeptide-8 rather than used alone.
- Acetyl Tetrapeptide-2 peptide
- Acetyl Tetrapeptide-2 is a four-amino-acid peptide used for the look of firmness, particularly in eye and neck formulas.
- Acetyl Tetrapeptide-3 peptide
- Acetyl Tetrapeptide-3 is a four-amino-acid peptide used for the look of density and firmness. It appears in scalp formulas as often as in facial ones.
- Acetyl Tetrapeptide-5 peptide
- Acetyl Tetrapeptide-5 is a four-amino-acid peptide used in eye products for the look of puffiness and crepiness.
- Acetyl Tetrapeptide-9 peptide
- Acetyl Tetrapeptide-9 is a four-amino-acid peptide used for the look of firmness and density. It is most often supplied alongside acetyl tetrapeptide-11.
- Carnosine antioxidant
- Carnosine is a small peptide of two amino acids that acts as an antioxidant, particularly against the sugar-driven damage formulators call glycation. It is used for the look of dull, sallow skin.
- Copper Tripeptide-1 peptide
- Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines.
- Nonapeptide-1 peptide
- Nonapeptide-1 is a nine-amino-acid peptide used for the look of uneven tone rather than for firmness, which makes it unusual among cosmetic peptides.
- Palmitoyl Pentapeptide-4 peptide
- Palmitoyl Pentapeptide-4 is the five-amino-acid peptide originally sold as Matrixyl. It is used for the look of fine lines and is one of the longest-standing cosmetic peptides.
- Palmitoyl Tripeptide-1 peptide
- Palmitoyl Tripeptide-1 is a short peptide with a fatty tail added so it can travel through the oily outer layer of skin. It is used for the look of firmness and is almost always paired with palmitoyl tetrapeptide-7.
- Palmitoyl Tripeptide-5 peptide
- Palmitoyl Tripeptide-5 is a fatted three-amino-acid peptide used for the look of firmness and fine lines. The palmitoyl tail is what lets it cross an oily surface.
- 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.
- 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.

How to use
- Use the Eyelash Treatment Serum at the end of the evening routine, on clean dry lashes.
- One pass of the applicator along the upper lash line, the way a liquid liner goes on. One coat is the dose, and a second pass over the same lashes does not add to it.
- Everything else in the routine goes on first. The lashes need to be clean and completely dry when it goes on, because eye cream, oil or leftover mascara gives it a film to sit on instead of the lash line.
- Once a day, in the evening. Do not run it along the waterline or let it into the eye itself; the base of the lashes is the closest it belongs.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Acetyl Glucosamine on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Acetyl Glucosamine rather than to three changes at once.
