Key benefits

- Niacinamide on the same list, an active
- Biotin on the same list, a vitamin

- Acorus Calamus Root Extract and Arginine further down the same list
- Panthenol and Sodium Hyaluronate further down the same list
Key actives
3Caffeineactive
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. On this ampoule's own ingredient list it is named third.
5Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named fifth on this ampoule's list, alongside Caffeine.
15Biotinvitamin
Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas. The panel names it fifteenth on this ampoule's list, beside Caffeine.
16Pueraria Lobata Root Extractplant extract
Pueraria Lobata is kudzu. Its root extract carries isoflavones, plant compounds structurally similar to oestrogen, and Korean formulas use it for the look of thinning, less resilient skin. It is named sixteenth on this ampoule's list, alongside Caffeine.
17Camellia Sinensis Root Extractplant extract
Tea plant root extract rather than leaf extract. The root carries saponins instead of the catechins concentrated in the leaf, so it has a mild self foaming character. The panel names it seventeenth on this ampoule's list, beside Caffeine.

Where each key active sits on the declared ingredient list, by entry number. Position is proportion: the further forward, the larger its share.
Where does this ampoule go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than an ampoule 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 Caffeine and not three changes at once.
What else is on the list besides Caffeine?
Niacinamide, Biotin and Pueraria Lobata Root Extract. The order they are printed in on this ampoule's panel is the order on the box, so you can see where Caffeine sits relative to them. Further down the same panel: Camellia Sinensis Root Extract, Acorus Calamus Root Extract and Arginine.

19 of 19 explained
- Water/Aqua/Eau 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Camellia Sinensis Leaf Water plant extract
- Camellia Sinensis Leaf Water is green tea distillate used in place of plain water as a base. It is far more dilute than the extract, so it sets the base rather than supplying the antioxidants.
- 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.
7 more explained
- 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.
- Alcohol solvent
- Alcohol here means ethanol. It dissolves ingredients water cannot, evaporates fast so a formula sets quickly and does not feel heavy, and thins texture. In quantity it can leave dry or reactive skin feeling tight, which is why many Korean formulas avoid it and some deliberately use it for a fast, weightless finish.
- Biotin vitamin
- Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
- Pueraria Lobata Root Extract plant extract
- Pueraria Lobata is kudzu. Its root extract carries isoflavones, plant compounds structurally similar to oestrogen, and Korean formulas use it for the look of thinning, less resilient skin.
- Camellia Sinensis Root Extract plant extract
- Tea plant root extract rather than leaf extract. The root carries saponins instead of the catechins concentrated in the leaf, so it has a mild self foaming character.
- Acorus Calamus Root Extract plant extract
- Sweet flag root extract, an aromatic wetland rhizome long used in Korean herbal practice. It is a conditioning plant extract.
- 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.

How it works
The HOUSE Power Eyelash Ampoule is a 6g ampoule, used after toner and before moisturizer, morning and evening. The active it is built around is Caffeine, named third on its own ingredient list. The same list carries Niacinamide, Biotin and Pueraria Lobata Root Extract, so the active is not the only thing on it worth naming. How much of the Caffeine stays on the skin, and for how long, is decided by the ampoule format rather than by the list alone. ETUDE sells this Caffeine ampoule in Korea, and this is that version.
How to use
- Use the HOUSE Power Eyelash Ampoule 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 ampoule on a small area and wait a day before using it more widely, especially with Caffeine on the list.
- Introduce this ampoule on its own for the first week, so anything your skin does is traceable to the Caffeine rather than to three changes at once.

It has also been proven that caffeine stimulates lipolysis, which Lupo et al postulated may contribute to improvements in lower eyelid sagging and puffiness.
Stacey J. PilkingtonDO, Azeal Dermatology Institute, The Journal of Clinical and Aesthetic Dermatology We find biotin to be very helpful for hair disorders. It also makes nails thicker, and oral biotin is exceedingly safe.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
