Monolid eyes: what they are, monolid vs hooded, and makeup

What is a monolid?

A monolid is an upper eyelid without a visible crease. When your eyes are open and relaxed, the skin runs smoothly from the lash line up to the brow instead of folding into two sections. The name simply means “one lid,” as opposed to a double eyelid, where a crease divides the lid into a lower part that moves with the eye and an upper part that stays put.

Monolids are very common in East Asian faces. Cleveland Clinic and All About Vision both put them at about half of people of Asian descent, and they also appear in people of many other backgrounds. Anatomically, the difference is mostly about where the soft tissue sits: in a monolid, the fat layer of the upper lid extends lower and the tissue that would form a crease doesn’t pull the skin in, so the lid stays smooth. Cleveland Clinic describes monolids as typically a harmless trait. They are a variation in how eyelids are built, not a problem to solve.

Monolids often come with an epicanthic fold, a small fold of skin that covers part of the inner corner of the eye. The two are separate traits, though. Some people have one without the other, and some articles use the terms loosely, which is part of why the topic gets confusing.

Monolid vs hooded eyes: what’s the difference?

Both can look similar in a photo, because in both you see little or no lid above the lashes. The difference is whether a crease exists. A monolid has no crease. A hooded eye has one, but skin from the brow bone drapes over it when the eye is open, so the crease is hidden. Hooded lids are common at any age and become more common as skin loosens over time, so someone can have double lids at 25 and hooded ones at 55. A monolid, by contrast, is how the lid has always been built.

There’s also a middle ground many people with East Asian features recognize: a low or partial crease that sits close to the lashes, sometimes visible only toward the outer corner. Makeup artists often call this an inner or tapered double lid. It behaves a lot like a monolid for makeup, because most of the lid you’d normally decorate is folded away when your eyes are open.

To check yours, use a mirror rather than a photo, and follow these steps in order.

• Face a mirror at eye level, relax your face and look straight ahead. Don’t raise your brows.
• Look for a line on the upper lid. If none shows, you most likely have monolids.
• Gently lift the skin under your brow with one finger. If a crease appears that was hidden, your lids are hooded.
• If a thin crease sits right at the lash line or only at the outer corner, you have an inner or partial double lid.
• Check both eyes. It’s common to have a crease on one side and not the other.

Can a photo tell if you have monolids?

Not reliably, and FaceRater doesn’t try. The landmark model behind the eye shape test finds 478 points on the face, including the corners of each eye and the edges of the lid opening, but it doesn’t trace the crease above the lashes. A smooth lid, a hidden crease and a faint crease can look nearly identical to it, so the test leaves eyelid type to your mirror instead of guessing.

What the photo does measure well are the other traits of your eye shape, and they apply to monolid eyes just as much: how open the eye is, which way the outer corner points and how far apart the eyes sit. Openness is the visible lid opening divided by the eye’s width, and the test calls anything from 0.31 to 0.37 almond. Monolid eyes can be almond, round or long and narrow, upturned or level, close-set or wide-set, just like any other eyes.

One note on tilt: in FaceRater’s reference photos, East Asian faces sit about 1.2° more lifted at the outer corner in their middle half than the set as a whole. The English eye shape test compares every face with the same bands, so a lifted, upturned reading is a little more common for East Asian faces. That’s a description of the angle, not a better or worse result.

Makeup for monolids: what works

The main thing to know about monolid makeup is that your open eye is what everyone sees, so plan for that view, not the closed-eye one tutorials often show. Shadow placed only on the lid can disappear completely when you look straight ahead. Work with gradients and height instead of a crease line, and check each step with your eyes open in a mirror at eye level.

None of this is about making monolids look like double lids. It’s about showing off the shape you have: a smooth lid is a great canvas for gradients, graphic liner and color.

• Start with an eyelid primer or a thin layer of concealer so shadow and liner don’t transfer when the lid folds against the brow area.
• Build shadow as a gradient: the deepest shade at the lash line, blended upward and lighter, so color still shows above the lashes when your eyes are open.
• Take shadow a little higher than you think you need, then open your eyes and check how much is visible.
• Keep liner thin at the inner corner and thicker toward the outer corner; a slightly winged end shows past the lid where a thin line would vanish.
• Tightlining (liner along the upper waterline) defines the eye without taking up lid space.
• Curl your lashes, since monolid lashes often point slightly down, and use a waterproof or tubing mascara to help the curl hold.
• A touch of light shimmer in the center of the lid or at the inner corner adds dimension on a smooth lid.

Brows and glasses for monolid eyes

Brows frame a monolid more than any other eyelid type, because there’s no crease line between the lashes and the brow to break up the space. A soft, straighter brow is common and suits many monolid eyes, while a gentle arch adds lift if you want a more open look. Map where the brow should start, arch and end from your own eye and nose rather than copying a shape from someone with a different lid.

With glasses, fit matters as much as style. Many East Asian faces have a lower nose bridge and fuller cheeks, so standard frames can slide down, sit on the cheeks when you smile or bring the lenses close enough for lashes to brush them. Frames sold as “low bridge fit” or “Asian fit,” or ones with adjustable nose pads, sit higher and a little further from the eyes. A frame whose top line follows your brow keeps the eye area clear.

Do monolids need to be changed?

No. Monolids are a normal, healthy eyelid type, shared by a huge number of people, and plenty of faces people admire have them. Some people choose eyelid tape or glue to create a temporary crease for certain looks, and others never would; both are personal choices, not corrections.

Double eyelid surgery (a type of blepharoplasty) exists, but it is a medical procedure with real risks and recovery, and whether it’s right for anyone is a decision to make with a qualified, board-certified surgeon, not something a face tool or article should push. A measurement tool, ours included, can only describe what a photo shows.

One thing worth separating: an upper lid that newly starts to droop, especially on one side, is different from a monolid. A drooping lid (ptosis) can have medical causes and is worth showing to an eye doctor. A monolid is simply how your lid has always looked.
