How it works
Powerproof Pen Liner #Black is a felt-tip eyeliner pen, applied along the lash line or in a wing shape depending on the look wanted. The pen tip gives more control for a precise line than a pencil or a brush-and-pot liner, which is the main reason people reach for this format. It is applied after eye makeup that goes underneath it, such as eyeshadow, and before mascara. Being marketed as smudge-resistant, it is built to hold its line through a normal day rather than needing frequent touch-ups. Removed at the end of the day, it comes off the same way the rest of eye makeup does, usually needing a dedicated remover for a long-wear formula.
Key benefits
- What it is: a liner from innisfree, for the eye makeup step.
- Format: a liner used along the lash line.
- Fits into the routine: draws a defined line along the lash line.
- Original Korean Formula: the version sold on Korean shelves, not a US reformulation.
Inside the formula
Inside the formula
How long does Powerproof Pen Liner #Black take to set?
A few seconds; let the line dry before blinking or it can transfer onto the lid above it. That holds true whichever size or variant of this product you buy, so the same placement in a routine and the same answer apply across the line.
Do I apply it before or after mascara?
Before. Eyeliner is generally applied after eyeshadow and before mascara, as the second-to-last step of eye makeup. That holds true whichever size or variant of this product you buy, so the same placement in a routine and the same answer apply across the line.
Is it waterproof?
Check the product page for the specific claim on this formula; a smudge-resistant liner and a fully waterproof one are not always the same thing. That holds true whichever size or variant of this product you buy, so the same placement in a routine and the same answer apply across the line.
How do I remove it?
A dedicated eye makeup remover works more reliably than a regular cleanser on a long-wear, smudge-resistant formula. That holds true whichever size or variant of this product you buy, so the same placement in a routine and the same answer apply across the line.
Can I create a wing with it?
Yes, the fine felt tip is built for controlled lines, which makes a winged shape easier than with a thicker liner format. That holds true whichever size or variant of this product you buy, so the same placement in a routine and the same answer apply across the line.

Ingredient list read from innisfree.com on 13 September 2026.
11 of 15 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.
- 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.
- 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 Benzoate preservative
- Sodium Benzoate is a mild preservative that works only in acidic formulas. It is usually paired with potassium sorbate, and the pair is the standard choice where a brand wants no phenoxyethanol.
- Potassium Sorbate preservative
- Potassium Sorbate is a preservative that holds off yeast and mould in acidic formulas. It is almost always used with sodium benzoate, because neither covers the whole range of microbes alone.
- 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.
- Sodium Hydroxide pH adjuster
- Sodium Hydroxide is a strong base used in traces to bring an acidic formula up to skin-friendly pH. None of it remains as itself once the formula is neutralised.
- 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.
- 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 to use
- Starting close to the lash line, draw a thin line from the inner to outer corner, adding a wing if wanted, and let it set for a few seconds before blinking. Apply it after eyeshadow and before mascara, as the last step of eye makeup before the rest of the face.
Worth knowing
- Let it set for a few seconds before blinking, since a fresh line can transfer if the eye closes too soon.
- Use a dedicated eye makeup remover at the end of the day, since a long-wear, smudge-resistant formula does not always come off with a light cleanser alone.
