Do you have an asymmetrical face and want to know how to improve it? In this complete guide, we explain what facial asymmetry is, what the causes are, and which treatments really work.
What is an asymmetrical face? (+ free self-test)
An asymmetrical face means that the left and right sides of your face differ noticeably. This is most visible with:
Asymmetrical eyes: different shapes or heights
Crooked face: caused by an asymmetrical jaw or nose
Uneven cheeks: one cheek fuller than the other
Different mouth corners: one side droops lower
Important: A completely symmetrical face does not exist. We only speak of facial asymmetry when the differences are clearly visible.
Free facial symmetry test (do it now)
Step 1: Take a selfie straight from the front (with good lighting!)
Step 2: Draw a vertical line through the middle of your nose
Step 3: Compare both halves carefully
Step 4: Assess: are the differences subtle or noticeable?
Tip: Also ask a friend to take a look — sometimes others see less than we do ourselves.
Asymmetrical face causes: what causes a crooked face?
1. Congenital causes of an asymmetrical face
Genetics: hereditary facial structure
Developmental disorders: during pregnancy
Birth trauma: from a difficult delivery
2. Asymmetrical face from sleeping and daily habits
Sleeping on one side is a very common cause. Years of sleeping on the same side create:
Pressure lines that become permanent
Uneven muscle development
Differences in skin firmness
Other daily causes:
Chewing on one side (always the same side)
Teeth grinding and jaw tension
Poor head posture during work
3. Medical causes of a crooked face
Facial paralysis (Bell’s palsy)
Stroke aftereffects
Trauma from accidents
Dental problems
Treating an asymmetrical face with Botox and fillers
Most facial asymmetry can be effectively treated with non-invasive treatments. Botox and fillers are the most popular and effective options for making your face more symmetrical.
Botox for an asymmetrical face
How does Botox work for asymmetry?
Botox relaxes overactive muscles on the stronger side of your face, creating more balance. It is the ideal treatment for dynamic asymmetry – differences caused by muscle activity.
Botox works best for:
Asymmetrical eye corners and crow’s feet
Drooping mouth corners
Uneven forehead lines and eyebrow position
Asymmetrical smile caused by muscle tension
One-sided jaw tension (masseter treatment)
Benefits of Botox for symmetry:
✅ Quick treatment (15–30 minutes)
✅ Minimal downtime
✅ Visible results after 3–7 days
✅ Natural-looking outcome
✅ Reversible (effects fade after 4–6 months)
Price of Botox for asymmetry: €200–400 per treatment
Duration of results: 4–6 months

Combination treatment: Botox + fillers
Best results for asymmetry
Many patients choose a combination of Botox and fillers for the best outcome:
Botox for muscle balance and dynamic correction
Fillers for volume and structural improvement
This combination provides the most natural and complete result for facial asymmetry.
When are other treatments needed?
For severe asymmetry caused by medical conditions, trauma, or congenital abnormalities, surgical procedures may be necessary. These are performed by plastic surgeons and fall outside the treatments available at cosmetic clinics.
Asymmetrical face from sleeping: how to prevent it

When to see a specialist for an asymmetrical face?
Go directly to a doctor if you have:
Sudden asymmetry (possible medical cause)
Pain or functional complaints
Problems with eating, drinking, or speaking
Consider treatment if you have:
Asymmetry that affects your self-confidence
Makeup can no longer mask the differences
Photos show clear unevenness
How to choose the best clinic for Botox and fillers?
Practitioner selection checklist:
✅ BIG-registered doctor (required for injections)

"Which brands of Botox/fillers do you use and why?"
"What happens if I am not satisfied with the result?"
"Can you show references of similar cases?"

Yes, everyone has slight asymmetries. Only when there are noticeable differences do we call them treatable asymmetries.
Partly yes, through good sleeping position, alternating chewing and healthy habits.
