The five eyeliner formats, compared honestly
Same pigment, very different tools. Here is how each format actually behaves on lids, not how the marketing describes it.
| Format | Precision | Longevity | Difficulty | Best for | The catch |
|---|---|---|---|---|---|
| Liquid (pen) | High | High once set | Medium | Wings, graphic lines, everyday definition with crisp edges | Hard to correct; tips fray with use; dries out faster than pots |
| Liquid (dip brush) | Highest | High once set | High | The sharpest possible wing; artists and patient perfectionists | Steepest learning curve of all formats |
| Gel (pot + brush) | High | High, especially waterproof gels | Medium | Tightlining, smoked-out lines, hooded eyes, brown-liner looks | Needs a separate brush; pots dry out if left open |
| Pencil | Medium | Medium | Low | Beginners, soft daily definition, quick corrections | Needs sharpening; harder pencils can tug the lid |
| Kohl | Low-medium | Low unless set | Low | Waterline, smoky eyes, deliberately lived-in looks | Transfers and fades; not the tool for crisp lines |
| Felt-tip / marker | High | Medium-high | Low-medium | Fast everyday wings without dip-brush skill | Tip softens over weeks; less ink control than a brush |
Two distinctions worth knowing before you buy
Waterproof is not smudge-proof. Waterproof formulas resist water and tears; smudge-proof formulas resist oil and friction, which is what actually destroys most liner by 3 pm. Oily lids need film-forming, smudge-proof formulas more than they need "waterproof" on the label. The chemistry is explained in this guide.
The waterline needs its own rules. Only use liners intended for the waterline (typically kohl or specific gel pencils), and expect any liner there to fade within hours; that is physiology, not product failure. There is also published research on lining inside the lash line, which we summarise in the tightlining guide.
Match the format to the job
By eye shape
Eight shapes on one chart. Hooded lids and monolids both punish thin lines, but for different reasons and with different fixes.
