Product details

Fine + superproof
An ultra-fine brush liner that draws crisp, thin lines in one stroke and doesn’t smudge.
CLIO’s Superproof Brush Liner pairs a slim, springy brush with an ink-tank pen, so colour flows evenly from the first touch to the end of the line. A special film-forming coat resists water and oil, so the line stays sharp for hours.

What’s inside
The ingredients doing the work
Superproof film formers
Flexible polymers that set into a thin coat over the line, so it resists water and oil without smudging.
No. 3, 6 of 16 on the list
Deep pigments
Iron oxides near the top of the list, plus carbon black, for a vivid black or a deep brown in one pass.
No. 2, 4, 11 of 16 on the list
Water-based ink
A fluid, water-based formula that feeds steadily from the ink tank to the brush tip.
No. 1, 5, 10 of 16 on the list

How to use
Clean lines, every time
- 1
Shake
Before use, shake the pen two or three times with the tip pointing down.
- 2
Draw
Draw along the lash line in one smooth stroke. Press lightly for a hairline, a little harder for a bolder line or wing.
- 3
Click shut
Close the cap until it clicks, so air can’t dry out the brush.
- 4
Store tip down
Keeping the tip pointing down helps the pen last longer.

Sharp from morning to night
A crisp, fine line that holds through water, oil and long days, without smudging.
Good to know
- 01 Kill Black is a deep, vivid black; 02 Kill Brown is a clear, deep brown.
- If the colour looks faint or skips, foundation or shadow may be stuck on the brush: wipe the tip gently with a wet tissue.
- Superproof: remove with an oil cleanser or cleansing balm, not water alone.
- Each pen holds 0.55 mL.
