Facial Exercises for Asymmetry: Causes, Safe Exercises and When to See a Doctor

Facial exercises for asymmetry can help you relax a tight side, use both sides of your face more evenly and notice one-sided habits, but they can’t change the bones, teeth or nerves that shape most asymmetry, and a perfectly symmetrical face isn’t a realistic goal. A small difference between your left and right side is normal; almost everyone has one. A sudden change is different: it can be a sign of a stroke or Bell’s palsy and needs medical help first.

First: when asymmetry is an emergency

Sudden asymmetry is a medical problem, not a cosmetic one, and no exercise should be your first step.

Call emergency services (999 in the UK, 911 in the US) straight away if one side of the face suddenly droops, someone can’t smile evenly or lift both arms, or their speech is slurred or confused. These are the FAST signs of a stroke: Face, Arms, Speech, Time to call (NHS: stroke symptoms).

If one side of your face becomes weak or hard to move over a few hours or days, ask for an urgent doctor’s appointment. This can be Bell’s palsy, and the NHS advises getting seen quickly because treatment works best when started early (NHS: Bell’s palsy). Bell’s palsy and a stroke can look alike, so any new facial weakness should be checked (Mayo Clinic).

Also see a doctor or dentist if one side is newly swollen, numb or painful, or the difference appeared after an injury.

If you’ve had Bell’s palsy or another facial nerve problem, face yoga is not a treatment for it. Any exercises for facial weakness should be planned and guided by your doctor or a specialist physiotherapist, because the wrong kind of effort can make some movements harder to control.

Is it normal to have an asymmetrical face?

Yes. Mild facial asymmetry is common and usually not a sign that anything is wrong. A review in an orthodontic journal describes facial asymmetry as common in the general population and often too subtle to notice without measuring (Thiesen et al., 2015). One eye may sit a little higher, one cheek may look fuller, or your smile may lift more on one side.

Most people notice their asymmetry in photos rather than in the mirror, for two reasons:

• You’re used to your mirror image. The mirror flips your face left to right. A photo shows the unflipped version, which can look oddly uneven simply because it’s unfamiliar.
• Close-up cameras distort. A 2018 analysis in JAMA Facial Plastic Surgery estimated that selfies taken about 30 cm (12 inches) from the face make the base of the nose look roughly 30% wider than in a photo taken from about 1.5 metres (5 feet) away (Ward et al., 2018). Tilt your head or hold the phone off-centre and one side of your face gets the same exaggeration.

So before judging, take a photo from a few feet away with the timer and your head level.

Common everyday causes of facial asymmetry

Most facial asymmetry comes from things exercise can’t reach, such as bone, teeth and age, with habits playing a smaller, less certain role.

• Genetics and bone structure. The two halves of your skull, jaw and cheekbones grow slightly differently. This is the biggest factor for most people.
• Teeth and bite. Missing teeth, crowding or a bite that shifts to one side can change how the lower face sits.
• Chewing on one side. Many people prefer one side. The research is mixed: in a large Finnish study of 748 adults, a preferred chewing side wasn’t significantly linked to facial asymmetry, but missing teeth on the opposite side were linked to which side people chewed on (Heikkinen et al., 2024). A strong one-sided habit is worth mentioning to a dentist, because it often points to a tooth or bite problem.
• Sleeping on one side. It’s often blamed online, but there’s little research on it. Pressing the same cheek into the pillow every night can leave creases and puffiness on that side that are more visible in the morning.
• Posture. Tilting your head or leaning on one hand can make one side of the neck and jaw feel tighter.
• Sun exposure. If one side of your face gets more sun, for example by a window, that side may show more sun damage over the years. Daily sunscreen is one of the most useful ways to slow premature skin aging (American Academy of Dermatology).
• Expression habits. Smiling more on one side, raising one eyebrow or clenching on one side are muscle habits. These are the part facial exercises can work with.

Habits to balance first

Before adding exercises, even out the daily habits that load one side of your face, since they run all day while a routine lasts minutes.

• Chew on both sides. Try switching sides during meals. If chewing on one side hurts or feels awkward, see a dentist rather than forcing it.
• Rotate your sleep side. Alternating sides, or spending part of the night on your back, is harmless and reduces pillow creases on one cheek.
• Check your head position. Raise your phone and screen to eye level, keep your ears roughly over your shoulders, and stop resting your chin on one hand. Our tech neck exercises help with the posture side.
• Unclench. Rest your tongue lightly on the roof of your mouth with your lips closed and teeth slightly apart. If one side of your jaw often aches or clicks, our jaw tension relief guide explains the signs that mean it’s time to see a dentist.

Balanced facial exercises for asymmetry

These four moves train control on both sides, so the aim is evenness and awareness, not strengthening one side. Do them slowly in front of a mirror, with about a third of your maximum effort, and always work both sides equally.

1. Mirror Smile Check (about 40 seconds)

1. Sit tall, relax your shoulders and look straight into a mirror.
2. Slowly spread your lips into a soft, closed-lip smile.
3. Watch both corners of your mouth. Try to let them rise at the same pace and to the same height, without forcing the lazier side.
4. Hold for about 3 seconds, then relax completely.
5. Repeat 6 to 8 times.

What you should feel: light, even work in both cheeks. If one side won’t respond the way the other does and this is new, stop and see a doctor.

2. O-Shape Pump (about 30 seconds)

1. Form a gentle “O” with your lips, keeping your teeth apart.
2. Lift your upper cheeks slightly as if smiling with your cheeks, not your mouth.
3. Release and repeat in a slow, steady rhythm, 8 to 10 times.
4. Check the mirror: both cheeks should lift together.

Common mistake: squinting or creasing the forehead. Keep your eyes soft.

3. Tongue Reach, Both Sides (about 40 seconds)

1. Stick your tongue out and reach toward the right corner of your upper lip.
2. Hold for a moment, then draw it back in and relax.
3. Repeat 4 to 5 times, then do exactly the same on the left.

What you should feel: work under the chin and along the side of the jaw. Stop if your jaw clicks or aches.

4. Cheek Air Shift (about 30 seconds)

1. Close your lips and puff a little air into your mouth.
2. Slowly move the air into your right cheek and hold for 2 to 3 seconds.
3. Move it across to your left cheek and hold for the same time.
4. Repeat 5 to 6 times each side, keeping the pressure gentle.

Common mistake: puffing hard. A light puff is enough; you’re practising control, not stretching the skin.

Mistakes to avoid

• Overworking the “weaker” side. Extra reps on one side can create new tension. Keep it equal.
• Forcing symmetry. Expressions are naturally a little uneven. Aim for relaxed, not identical.
• Pushing through pain. Stop any move that hurts, clicks or tingles.

Safety: skip these moves and talk to a clinician first if you have current facial weakness or numbness, jaw joint (TMJ) pain, or recent facial surgery, injectables or dental work. For more ideas, see our guides to 12 face yoga exercises for every area and cheekbone exercises, and the face muscles guide if you’d like to know which muscles you’re using.

Massage and relaxation for the tighter side

If one side of your face or jaw feels tighter, gentle massage may help it feel looser, but do the same strokes on both sides.

1. Jaw muscle circles. Find the chewing muscle in front of your ear (it bulges when you clench). With teeth apart, make slow circles with your fingertips for about 20 seconds each side.
2. Cheekbone glide. Glide your fingers from beside your nose along the underside of the cheekbone toward your ear, 4 to 5 times per side.
3. Neck finish. Sweep from below each ear down the side of the neck toward the collarbone.

With a stone, hold it almost flat and press lightly. Our step-by-step gua sha for the jawline guide covers the lower face, and how to relax face muscles has more ways to release tension.

What exercises can and cannot change

Facial exercises may improve muscle control and awareness, but they can’t change bone, teeth or nerve damage, and there’s no research on them for asymmetry.

Can be influenced by habits and exercise	Can’t be changed by exercise
Muscle tension on one side	Bone structure of the skull and jaw
Awareness of one-sided expressions	Bite and tooth position
Posture and head tilt	Nerve damage from facial palsy or injury
Pillow creases and morning puffiness	Asymmetry present since birth

The best-known face yoga study was about aging, not asymmetry. In a small pilot, 27 women aged 40 to 65 enrolled and 16 completed 20 weeks of facial exercises (30 minutes daily for 8 weeks, then every other day). Dermatologists rating standardised photos saw fuller upper and lower cheeks, and estimated age dropped from 50.8 to 48.1 years on average (Alam et al., 2018). There was no control group, so larger controlled studies are needed. Our article on whether face yoga works looks at the evidence in more detail.

If an asymmetry bothers you, a dentist, orthodontist or doctor can explain its cause.

Track it with consistent photos

Because any change will be slow and subtle, compare careful photos over months instead of checking the mirror every day.

• Same setup. Same room, light and camera.
• Distance, not close-ups. Prop the phone at eye level about 1.5 metres (5 feet) away and use the timer, to avoid selfie distortion.
• Neutral face. Head level, lips gently closed, teeth apart, no smile. Add one photo with a relaxed smile if expressions are your focus.
• A fixed rhythm. Every few weeks, compare your newest photos with your first set, and note how your jaw feels.

Our face yoga before and after guide has a full checklist.

Practise both sides evenly with Gluvy

Gluvy’s face yoga video workouts include full-face plans that work both sides of your face in short, follow-along videos with a timer on every step, usually 5 to 10 minutes a day as part of a 3-week plan. The library has more than 200 guided exercises across the face, and a jaw relaxation routine helps when one side feels tense. The AI face analysis offers a starting-point analysis that suggests focus areas; it isn’t a medical diagnosis and can’t tell you why your face is asymmetric. A private progress journal with selfies keeps your photos in one place. When you’re ready, download Gluvy for iPhone, or browse more facial exercises by area.
