Can You Change Your Canthal Tilt? How to Fix Negative and Get Positive Tilt
You can't change your canthal tilt naturally — the angle is set by bone and by the tendon that anchors the outer corner of your eye, and only surgery moves it. What you can change is how your eyes read: brows, eyeliner, puffiness, and camera angle all shift whether the outer corner looks lifted or dropped.
Canthal tilt is the angle between the inner and outer corners of the eye. If you're not sure whether yours is positive, neutral, or negative, start with how canthal tilt is measured.
It's also one trait among many. How attractive a face reads depends on the whole picture — symmetry, skin, jawline, proportions — which is what an attractiveness test looks at, rather than a single angle.
Can You Change Your Canthal Tilt Naturally?
No — not the angle itself. Canthal tilt depends on where the lateral canthal tendon attaches to the bony rim of the eye socket, and no exercise, massage, or habit moves that attachment. Natural methods can only change how the eye area looks around a tilt that stays the same.
Here's what holds the angle in place:
The lateral canthal tendon — a band of tissue that anchors the outer corner of the eyelids to the lateral orbital rim (Kim et al., 2016).
The bone it attaches to — the shape and height of the eye socket rim.
Stability in adulthood — in a study of 320 people aged 10–89, the position of the outer eye corner didn't change with age (van den Bosch et al., 1999).
So when people online say they "fixed" their tilt naturally, what usually changed is the frame around the eye — not the angle.
Method | Changes the angle | Changes how the eye looks |
|---|---|---|
Canthoplasty or canthopexy (surgery) | Yes | Yes |
Brow shaping | No | Yes |
Eyeliner and lashes | No | Yes |
Less puffiness, better sleep | No | Yes |
Head and camera angle | No | Yes, in photos |
Eye exercises, face yoga, mewing | No | No evidence |
Pulling or taping the skin | No | No |
Does Canthal Tilt Change With Age?
Canthal tilt can shift a little during the teen years and then stays stable through adulthood. In a 2024 study, males aged 10–19 had a tilt about 1.6° lower on average than those aged 20–29, with little change after 20 (Shao et al., 2024).
During puberty
The eye area is still growing: between about 12 and 25, the eye opening gets roughly 3 mm wider (van den Bosch et al., 1999).
A tilt that measures neutral or slightly negative at 14 isn't necessarily where it will end up.
Measuring your tilt from photos at this age tells you about now, not about your adult face.
In adulthood
The outer eye corner itself doesn't move with age (van den Bosch et al., 1999).
What changes is the area around it: the lower eyelid sags slightly with age — about 1 mm in men and 0.5 mm in women in the same study.
That can make the eyes look more downturned over time, even though the measured angle stays the same.
How to Get a Positive Canthal Tilt Look Without Surgery
You can make a neutral or negative canthal tilt read as more lifted by changing what frames the eye: the brows above it, the lines and lashes along it, and the puffiness or shadows under it. None of this changes the angle, but it changes the first impression of the eye area.
Shape the Outer Brow
The brow tail sets the line the eye is read against. A tail that droops below the outer eye corner pulls the whole area down.
Remove stray hairs under the outer third of the brow so the tail sits level or slightly higher.
Keep the tail — don't over-thin it. A sparse tail can make the outer eye look lower.
Brush brow hairs up and slightly outward with a clear brow gel.
For a straighter, lower brow — the look behind hunter eyes — keep the arch minimal and the tail level.
Use Eyeliner to Lift the Outer Corner
Eyeliner is the most direct way to change how the tilt reads, because it draws a new line at the exact spot that sets the angle.
Keep the line on the upper lash line only, or very light on the outer lower lash line.
End the line with a short upward flick that follows the outer brow, not the lower lid.
Skip heavy liner along the whole lower lid — it frames the downturn instead of hiding it.
For step-by-step liner shapes for a downturned outer corner, see eyeliner for negative canthal tilt.
Curl and Emphasize the Outer Lashes
Curl lashes and focus mascara on the outer third.
Brush outer lashes up and outward, not straight up.
For men, curling and a clear mascara or brow gel work without a visible makeup look.
Reduce Puffiness and Under-Eye Shadows
Swelling and dark circles under the eye add visual weight to the lower lid and make the outer corner look lower.
Get consistent sleep — puffiness is usually worse after short nights.
Cut back on salt and alcohol in the evening if you wake up puffy.
Sleep with your head slightly raised.
Use a cold compress in the morning.
Use concealer only under the inner and middle part of the eye, not dragged down from the outer corner.
Check Your Head Angle in Photos
Canthal tilt measured from a photo depends on the camera and your head position.
Tilting your chin down makes the outer corners look lower; a level head or a very slight chin-up reads more neutral.
Shoot at eye level — a camera held below the face exaggerates a downturn.
Before judging your tilt from a selfie, take a straight-on photo with a level head and neutral face.
What Doesn't Change Your Canthal Tilt
Eye exercises, face yoga, mewing, and pulling or taping the skin around the eyes don't change canthal tilt. No study has shown any of them moving the outer eye corner, and the tendon that sets the angle isn't something a muscle exercise can reposition.
These methods spread fast in looksmaxxing videos because before-and-after clips look convincing. But lighting, head angle, brow grooming, and a less puffy morning can all change a photo without any change in the angle.
Eye Exercises and Face Yoga
The best-known study of facial exercise was a small 20-week pilot in middle-aged women, looking at signs of facial aging — not at eye shape or canthal tilt (Alam et al., 2018).
One of its authors founded the face yoga program the participants used.
There's no research on exercises changing canthal tilt.
Mewing
Mewing is a tongue-posture habit aimed at the jaw and lower face.
There's no evidence that it changes the position of the outer eye corner.
Claims that mewing "lifts" the eyes come from personal before-and-after photos, not studies.
Pulling, Taping, or Gua Sha Around the Eyes
Pulling the outer corner up with your fingers or tape changes the look only while it's held.
The skin around the eyes is thin, and repeated stretching or rubbing it won't reshape the tendon underneath.
Rubbing near the eye with tools or fingers can irritate the skin and the eye itself.
"Hunter Eye" Routines
Videos promising “hunter eyes in 30 days” usually combine brow grooming, squinting, and photo angles.
These can change how the eyes look in a clip, but not the angle you'd measure on a neutral, straight-on photo.
How to Fix a Negative Canthal Tilt With Surgery
The only way to permanently change canthal tilt is eyelid surgery on the outer corner of the eye, usually lateral canthoplasty. A surgeon detaches the outer corner and re-anchors it to the eye socket rim at a new height (Kim et al., 2016). It's a real operation with real risks, not a cosmetic tweak.
Canthoplasty and Canthopexy
Lateral canthoplasty — the outer corner is released and fixed to the orbital rim in a new position. Depending on where it's fixed, it can change the eye's slant or lengthen the eye (Kim et al., 2016).
Lateral canthopexy — a related procedure you'll often see mentioned next to canthoplasty. A surgeon can explain which one fits your case.
Why it's done — in the US and Europe, canthoplasty is often done to lift an outer corner that has dropped, usually with age. In East Asia, a cosmetic version is commonly done for the opposite reason: to lower the slant so the eyes look larger and softer (Kim et al., 2016). There's no single "correct" tilt that surgery aims for.
Risks of Canthal Surgery
Complications reported after lateral canthal surgery include:
A misshapen or rounded outer corner of the eye (Kim et al., 2016; Homer et al., 2020)
Recurrence — the corner drifting back toward where it was, so the result fades
The lower lid turning outward (ectropion) or showing the pink inner lining, which can cause dry eyes
A corner placed too low or in the wrong spot (canthal malposition)
Rarely, tears leaking through the skin near the outer corner, which needs another operation (Zhang et al., 2020)
Some of these problems can be fixed with another surgery, and some can't (Zhang et al., 2020).
Who Performs It
Canthal surgery is done by oculoplastic surgeons (ophthalmologists who specialize in the eyelids and eye socket) and by facial plastic surgeons.
If you're considering it, talk to a board-certified specialist about what's realistic for your face, which technique they'd use, and how often they see complications.
If you're still in your teens, keep in mind that tilt can shift until around 20 (Shao et al., 2024).
FAQ
Can you actually fix a negative canthal tilt?
Only with surgery, such as lateral canthoplasty, which re-anchors the outer eye corner higher. Without surgery, you can make a negative tilt look more neutral with brow shaping, eyeliner, lashes, and less under-eye puffiness, but the angle stays the same.
How do you turn a negative canthal tilt into a positive one?
Permanently, only through surgery. Visually, lift the outer brow tail, draw an upward eyeliner flick on the upper lash line, curl the outer lashes, and avoid heavy liner along the lower lid.
Is canthal tilt genetic?
No study has measured how much canthal tilt itself is inherited. But the shape of the eye area is strongly genetic: in a 3D face study of UK twins, the region around the inner eye corners and the bone lines around the eye sockets were among the most heritable parts of the face (Tsagkrasoulis et al., 2017). More on what sets it in our canthal tilt guide.
Does mewing change canthal tilt?
No. Mewing is a tongue-posture habit aimed at the jaw, and there's no evidence it moves the outer corner of the eye.
Can uneven eyes go back to normal?
Small differences between the left and right eye are common, and photos often make them look bigger than they are. If one eye has changed shape recently, or one lid droops more than before, see an eye doctor rather than trying to fix it yourself.
Is a negative canthal tilt bad?
No. Negative, neutral, and positive tilts are all normal variations. What a negative tilt looks like and why it's common is covered in negative canthal tilt explained.
