Monolid vs Double Eyelids: The Difference, Plus How to Tell Yours
Monolid vs double eyelids is a one-fold difference. A double eyelid has a visible crease above the lashes that splits the lid in two. A monolid has none, so the lid runs smooth from lash line to brow.
I spent years assuming everyone had a crease, because every tutorial I watched started with one. Then a friend showed me her routine and there was no crease step at all. Watching her blend shadow upward from the lash line rewired how I think about lids.
Quick answer
A double eyelid has a visible supratarsal crease that divides the upper lid into a small strip near the lashes and a taller space above. A monolid has no crease. Between them sit low creases, tapered and parallel folds, and hooded lids, and plenty of people have one of each.

What each term means
Monolid. No supratarsal crease. The upper lid is one smooth plane, the lashes often angle downward, and the lid may sit close over the lash line. Common in East Asian populations and present in every population. More in the monolid eyes guide.
Double eyelid. A visible crease arcs above the lashes, leaving a strip of lid, the platform, between the lashes and the fold. It is the default anatomy in most Western makeup tutorials. More in the double eyelids guide.

On a portrait, look for the strip of lid between the lashes and the crease line. A defined crease leaves that strip visible; a monolid shows one smooth plane.
Monolid vs double eyelids chart
| Monolid | Double eyelid | |
|---|---|---|
| Crease | None | Visible fold above the lashes |
| Visible lid platform | None or minimal with eyes open | A strip of lid shows below the crease |
| Lash angle | Often straight or downward | Usually outward or upward |
| Shadow technique | Gradient blended up from the lash line | Crease work and outer-V placement |
| Liner behavior | Thicker bands read cleanly | Thick bands eat the platform |
The in-between creases
Monolid and double are the ends of a spectrum, not two boxes. The middle is crowded.
- Low crease. A fold that sits close to the lash line, leaving a narrow platform. Reads almost monolid with the eyes open.
- Tapered crease. The fold merges with the inner corner and rises toward the outer corner. Common alongside an epicanthic fold.
- Parallel crease. The fold runs level with the lash line, clear of the inner corner. The style most Western tutorials assume.
- Hooded double. A crease exists, but skin from the brow bone folds over and hides it. Makeup behaves closer to monolid rules. See hooded eye makeup.
How to tell which one you have
- Face a mirror at eye level, eyes open and relaxed, brows down.
- Look for a fold line above your upper lashes. A clear arc from inner to outer corner means double eyelid.
- No fold at all, with smooth skin from lashes to brow, means monolid.
- A fold that hides when your eyes open, or only shows at the outer half, means a low or hooded lid, not a true monolid.
- Check each eye separately. One of each is common enough to have its own tutorials.
A straight-on photo at eye level shows the crease more honestly than a mirror, because mirrors invite you to raise your brows and lift the lid.
One of each?
Asymmetric lids, one monolid and one double, are a normal variation. Makeup can even them out: match the double-lidded eye's crease with shadow placement on the monolid side, or use the gradient technique on both so the difference stops reading on camera. Eyelid tape is the other common fix, covered below.
Where the difference comes from
The crease forms where fibers from the muscle that lifts the lid, the levator, attach to the skin. Strong attachments pull the skin into a fold when the eye opens, producing a double eyelid. Weak or absent attachments leave the lid smooth, producing a monolid. It is anatomy you are born with, and it runs in families.
Age moves the line too. Skin loses elasticity, so a crease can hood over in later decades, and a low crease can vanish under the fold. A crease appearing or disappearing suddenly, on one side, is worth mentioning to a doctor.
What it means for makeup
- Monolids build depth as a gradient from the lash line upward, since there is no crease to blend into. The monolid eye makeup guide has the full routine.
- Double eyelids follow the crease: transition shade in the fold, depth at the outer corner, lid shade on the platform.
- Low and hooded creases borrow from both: place color with the eyes open so it survives the fold.
- Lash curl matters most on monolids, where lashes often point down. On double lids the platform shows mascara smudges faster, so set liner before mascara.
Can you change a monolid into a double eyelid?
Temporarily, yes. Eyelid tape and lash glue pressed into the lid can hold a fold for the day, and a firm false-lash band can push one up. They take practice, and daily adhesive on lid skin deserves a light touch.
Permanently, only surgery. Double eyelid surgery, a form of blepharoplasty, creates a crease by suturing or incising the lid. It is one of the most common cosmetic procedures in East Asia, and like any surgery it carries cost, recovery time, and risk. Creams, exercises, and massage do not create a crease. If you consider surgery, consult a board-certified surgeon and expect them to assess your lid anatomy in person.
Frequently asked questions
Are monolids rare?
No. They are the majority lid type in many East Asian populations and appear in every population. Nobody runs a global eyelid census, so treat any percentage online with suspicion.
Can a monolid become a double eyelid with age?
The lid changes with age, but usually toward hooding, since skin loses elasticity and folds over the crease. A true monolid rarely grows a crease on its own.
Is a monolid the same as a hooded eye?
No. A monolid has no crease at all. A hooded eye has a crease hidden under a skin fold. Makeup behaves similarly on both, which is why the techniques overlap.
Is it common to have one monolid and one double eyelid?
Yes, asymmetric lids are a normal variation. Makeup placement or eyelid tape can even them out for photos.
What makeup works for monolids vs double eyelids?
Monolids use a vertical gradient from the lash line up and rely on lash curl. Double eyelids use crease-based placement with depth at the outer corner. Low and hooded creases mix both.
