A monolid is an eyelid without a visible crease between the lashes and the brow bone. The lid is one smooth plane, and the skin at the lash line folds inward when the eye opens. A line that looks bold on the closed lid can be a hairline, or nothing at all, on the open one.
The rules for monolid liner are the reverse of the rules for most other shapes. Thicker works better than thinner, straight works better than steep, and colour shows better than most people expect. Make-up artists compiled by AOL put it plainly: monolids take far more colour than they are given credit for.
What is a monolid and why does a thin line vanish?
A monolid is an eye shape in which the upper lid has no crease, or a crease so low that it is hidden when the eye is open. It is common in East and Southeast Asian faces and occurs in every population. The lid skin is often smoother and slightly fuller at the lash line than on a creased eye.
When a monolid opens, the lid skin nearest the lashes rolls under the fold above it. Any line drawn on that strip of skin goes with it. A line 1 mm thick on the closed lid can disappear entirely; a line 3 mm thick may show as 1 mm. The line has to be drawn for the open eye, and it has to be drawn wider than the eye that is used to a crease would ever draw it.
How thick should eyeliner be on a monolid?
Thicker than feels natural on the closed lid. Draw with the eye open and look straight into the mirror. Build the line in short strokes and stop when the open eye shows a clean band of colour along the lashes, usually 2 to 4 mm at the outer half. That band may look heavy when the eye is closed; the closed eye is not the one that is worn.
Daily Vanity's monolid guide gives the same instruction and adds a check: open both eyes, look ahead, and widen the line only where it has disappeared (Daily Vanity). Keep the inner third thinner than the outer two-thirds, so the line tapers and the eye looks longer.
Which wing shapes suit monolids?
| Shape | Direction of the wing | Effect on a monolid |
|---|---|---|
| Natural straight wing | Continues the lash line straight out, little or no lift | Lengthens the eye without a hook; the safest default |
| Cat eye | Up and out along the lower lash line | Works when kept short; a steep flick can look detached from the lid |
| Puppy liner | Follows the lid's downward curve, wing points slightly down and out | Softer and rounder; keep it aligned with the inner corner to avoid a droop |
| Thick lash-line band | No wing, a solid 2 to 4 mm band along the upper lashes | Bold definition that shows when the eye is open |
| Tightline | Pencil between the lashes and on the upper waterline | Density with no lid space used; pairs with any shape |
Daily Vanity's rule for puppy liner on a monolid is to keep the wing aligned with the inner corner of the eye, so the result reads as a soft extension and not as a droop (Daily Vanity). Bangstyle's eye-shape guide lists cat, puppy and natural straight wings as the three monolid options (Bangstyle).
How do you draw puppy liner in six steps?
Puppy liner is the inverse of a cat eye. The line follows the natural downward curve of the upper lid and the wing points down and out, which gives a softer, rounder and younger look (Beauty Crew).
You will need
- A felt-tip liquid liner, or a gel pencil for a softer edge
- A soft pencil in the same colour, for mapping
- A mirror at eye level in daylight
- A cotton bud with micellar water for corrections
- Look straight ahead with both eyes open. With the pencil, mark a small dot 2 to 4 mm past the outer corner, level with the outer corner or a fraction lower, in line with the inner corner of the eye.
- Draw a line from the inner third of the upper lashes to the outer corner, pressed into the lash base. Thicken it steadily toward the outer corner.
- Extend the line from the outer corner to the dot, following the downward curve of the lid.
- Check with the eye open. Widen the band wherever it has vanished under the fold, until a clean line shows along the whole lash line.
- Trace the mapped shape with the liquid liner and fill the wing.
- Wait 30 seconds with the eye open before blinking. Tidy the lower edge of the wing with a cotton bud so the line does not pull the eye down.
How do you tightline a monolid?
Tightlining presses a pencil into the upper waterline and the gaps between the lash roots, so the lash line looks denser with no drawn edge. On a monolid it is the one technique that adds definition without using any lid space, and it stops a thick band from looking as if it floats above the lashes.
Use a sharpened, waxy, waterproof pencil. Lift the lid gently with a fingertip under the brow, look down into the mirror, and press the pencil into the lash base in short strokes at about 45 degrees, as Bangstyle's guide advises for monolids. Eye-care professionals warn that any product on the waterline blocks the oil glands along the lid margin (Coveteur), so keep most of the pigment on the lid side of the roots, use it occasionally, and replace the pencil after three months of waterline use.
Which colours show on a monolid?
Deep colours. A monolid has a wide, uninterrupted lid, and once the line is drawn thick enough to show, it can be any shade that is dark enough to read at a distance. Deep plum, navy and forest green give the definition of black with a softer edge, and they show as colour up close.
Metallic gold along the lower lash line or at the inner corner brightens the eye without adding width to the upper lid. India Anaïs Plum Ink, a gel pencil in a plum that reads as black from a distance and violet up close, was designed for this use; the first edition is sold out, and the next edition is planned for spring 2027. Colour placement by eye colour follows the colour wheel: bronze and gold against blue eyes, plum against green, navy against brown (Jane Iredale).
What mistakes make a monolid look heavy?
A thick line at the inner corner. The band should taper: thin at the inner third, full at the outer. A line that is 3 mm along its whole length closes the eye and shortens it.
A wing that points down without the puppy alignment. If the tip drops below the line of the inner corner, the whole eye reads as drooping. Keep the tip level with the outer corner or a fraction lower, never more.
Black on the lower waterline. It rims the eye and, with a thick upper band, leaves no light in it. A nude pencil on the lower waterline and a soft brown shadow smudged under the outer lower lashes keep the eye open while the upper line does the work.
- On a monolid, draw the line thicker than feels natural and check it with the eye open.
- Taper the band from thin at the inner corner to 2 to 4 mm at the outer half.
- A natural straight wing or a puppy wing aligned with the inner corner suits the shape better than a steep cat eye.
- Tightlining adds density behind the lashes without using lid space; keep it occasional and use a sharpened pencil.
- Monolids take deep colour well: plum, navy and forest green read as definition up close and as black from a distance.
Questions people ask
Why does my eyeliner disappear on my monolid?
The lid skin nearest the lashes folds inward when the eye opens, and the line goes with it. Draw with the eye open, build the line wider than feels natural, and check after every few strokes.
Should monolids wear winged eyeliner?
Yes. A short straight wing that continues the lash line works on almost every monolid. A puppy wing aligned with the inner corner gives a softer look. Keep a cat-eye flick short so it stays attached to the lid.
Is liquid or pencil eyeliner better for monolids?
Liquid draws the clean, opaque band that a monolid needs and does not transfer when the lid folds. A gel pencil works for a smudged look and for tightlining. Many people map with a pencil and trace with liquid.
Does tightlining help monolids?
It helps a great deal. It thickens the lash base without using any lid space and anchors a thick line so it does not look as if it floats. Use a sharpened waxy pencil and keep it to occasional use, because product on the waterline blocks the oil glands.
