Key actives
2Biotinvitamin
Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas. On this serum's own ingredient list it is named second.
6Aloe Barbadensis Leaf Extractplant extract
Aloe Leaf Extract is mostly water with polysaccharides, amino acids and mild plant acids. It hydrates and leaves a light, cooling film, which is why it is the default after-sun ingredient. The panel names it sixth on this serum's list, beside Biotin.
7Panax Ginseng Root Extractplant extract
Ginseng Root Extract is the signature ingredient of Korean traditional skincare, carrying ginsenosides. It is used for the look of tired, dull skin, and brands often ferment it to break the ginsenosides into smaller forms. The panel names it seventh on this serum's list, beside Biotin.
12PEG-32humectant
PEG-32 is a longer polyethylene glycol. It is a humectant that also adds a little body to a watery formula. It is named twelfth on this serum's list, alongside Biotin.
16Swertia Japonica Extractplant extract
Japanese swertia extract, a bitter herb used in Korean and Japanese scalp formulas. It is a conditioning plant extract. The panel names it sixteenth on this serum's list, beside Biotin.

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 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 Biotin and not three changes at once.
What else is on the list besides Biotin?
Aloe Barbadensis Leaf Extract, Panax Ginseng Root Extract and Swertia Japonica Extract. The order they are printed in on this serum's panel is the order on the box, so you can see where Biotin sits relative to them. Further down the same panel: PEG-32 and Sodium Hyaluronate.

14 of 24 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.
- Biotin vitamin
- Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
- 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.
- 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.
- 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.
- Aloe Barbadensis Leaf Extract plant extract
- Aloe Leaf Extract is mostly water with polysaccharides, amino acids and mild plant acids. It hydrates and leaves a light, cooling film, which is why it is the default after-sun ingredient.
- Panax Ginseng Root Extract plant extract
- Ginseng Root Extract is the signature ingredient of Korean traditional skincare, carrying ginsenosides. It is used for the look of tired, dull skin, and brands often ferment it to break the ginsenosides into smaller forms.
- Phenoxyethanol preservative
- Phenoxyethanol is the most widely used cosmetic preservative outside the paraben family. It keeps a water-containing formula from growing bacteria and mould, and is capped at one percent in most markets, so it always sits low on a list.
- 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.
- 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.
- Peg-32 humectant
- PEG-32 is a longer polyethylene glycol. It is a humectant that also adds a little body to a watery formula.
- 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.
2 more explained
- Swertia Japonica Extract plant extract
- Japanese swertia extract, a bitter herb used in Korean and Japanese scalp formulas. It is a conditioning plant extract.
- 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.

How it works
The HOUSE My Lash Serum Eyelash Serum is a 9g serum, used after toner and before moisturizer, morning and evening. The vitamin it is built around is Biotin, named second on its own ingredient list. The same list carries Aloe Barbadensis Leaf Extract, Panax Ginseng Root Extract and Swertia Japonica Extract, so the vitamin is not the only thing on it worth naming. How much of the Biotin stays on the skin, and for how long, is decided by the serum format rather than by the list alone. ETUDE sells this Biotin serum in Korea, and this is that version.
How to use
- Use the HOUSE My Lash Serum Eyelash 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 Biotin on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Biotin rather than to three changes at once.

We find biotin to be very helpful for hair disorders. It also makes nails thicker, and oral biotin is exceedingly safe.
