Facial Symmetry: Why It Matters and 9 Ways to Look More Symmetrical

Look closely at any face and you'll notice one eye sits a little higher, one side of the smile lifts more, or the jaw is slightly stronger on one side. That's completely normal. Still, facial symmetry is one of the most researched factors in attractiveness — and one of the biggest inputs into an AI face rating. Here's what you need to know.

Why does facial symmetry matter?

Studies across cultures have found that people tend to rate more symmetrical faces as more attractive. One popular explanation is that symmetry acts as a subtle signal of healthy development. Symmetry also simply makes a face look more balanced and harmonious.

That said, perfect symmetry isn't the goal. Artificially perfect mirrored faces often look uncanny — slight asymmetry adds character.

What causes facial asymmetry?

• Genetics and natural development — the most common cause
• Sleeping on one side night after night
• Chewing mostly on one side
• Dental issues such as missing teeth or bite problems
• Posture habits like leaning your face on one hand
• Sun damage and aging, which can affect sides differently
• Injury or medical conditions — sudden asymmetry (e.g., one side of the face drooping) needs immediate medical attention

How to test your facial symmetry

1. Take a straight-on photo at eye level in even light.
2. Draw a vertical line through the middle of your face.
3. Compare the height of your eyes, brows, ears and mouth corners.
4. Compare jaw and cheek width on each side.

For an objective number, an AI tool measures all landmarks at once. Try the facial symmetry test — it gives you a symmetry score out of 10 plus a golden ratio breakdown.

9 ways to look more symmetrical

1. Switch your sleeping position

Sleeping on your back avoids pressing one side of your face into the pillow every night.

2. Chew evenly

If you always chew on one side, consciously alternate. Over long periods this may help keep jaw muscles more balanced.

3. Shape your brows

Brows frame your eyes. Grooming them to a matching height and shape is one of the fastest ways to make your face look more even.

4. Choose a hairstyle that balances

A side part on the "fuller" side or a slightly asymmetrical cut can visually offset asymmetry. See how to find your face shape for cuts that suit you.

5. Style your beard strategically

Men can trim a beard slightly fuller on the narrower side of the jaw.

6. Use makeup contouring

Contour and highlight can even out cheekbone height and jawline differences.

7. Fix your posture

Forward head posture and habitually tilting your head can make asymmetry more obvious, both in person and in photos.

8. Take care of your skin

Uneven pigmentation and sun damage on one side (common in drivers) make faces look less even. Daily sunscreen helps.

9. Find your better side for photos

Most people have a side that photographs better. Take photos at eye level, not too close, and experiment with a slight turn toward your stronger side.

Significant asymmetry caused by dental or jaw problems is best discussed with a dentist or orthodontist.

FAQ

Is it normal to have an asymmetrical face?

Yes. Virtually everyone has some facial asymmetry. It usually only becomes noticeable in photos, which flip or distort your features compared to what you see in the mirror.

What is a good facial symmetry score?

Most faces score between 6 and 8 out of 10 in Aesthetica's symmetry analysis. Above 8.5 is very high symmetry.

Can mewing fix facial asymmetry?

There's no strong scientific evidence that mewing corrects facial asymmetry in adults.

Why does my face look asymmetrical in photos but not in the mirror?

The mirror shows a flipped image you're used to seeing, and front cameras held close exaggerate differences. A camera at arm's length and eye level gives a more accurate picture.
