Key Points
- Droopy eyebrows (brow ptosis) mean the brow sits lower than it should, pushing weight onto the upper eyelid and making the eyes look tired or cross.
- A dropped brow, a dropped eyelid and excess eyelid skin look alike but need three different treatments, so check which you have first.
- Ageing is mostly volume loss, not gravity. The fat over the eyebrow bone deflates, so the brow sits lower and the brow ridge shows more.
- Forehead injections placed too low can drop the brow. Trials show injecting higher on the forehead protects brow position, and the effect wears off in three to four months.
- A brow lift moves soft tissue; brow bone surgery reshapes bone. Muscle-relaxing injections give a modest, temporary lift of a few millimetres.
- A brow that drops on one side suddenly needs medical assessment, urgently if there is facial or limb weakness or slurred speech.
Droopy eyebrows — clinically called brow ptosis or eyebrow ptosis — occur when the eyebrow sits lower than it should, pushing the weight of the brow tissue down onto the upper eyelid. Drooping eyebrows make the eyes look smaller and heavier, can give a permanently tired, cross or sad expression, and in more pronounced cases restrict the upper field of vision.
The distinction that matters most is between a brow that has dropped, an eyelid that has dropped, and simple excess skin. They look similar in the mirror and need entirely different treatments — a point covered below with a self-test you can do now.
This guide covers what causes sagging eyebrows, how to tell brow ptosis from eyelid problems, how to lift eyebrows without surgery and where that genuinely works, the surgical options, and the one increasingly common cause most guides leave out.
What are droopy eyebrows (brow ptosis)?
Droopy eyebrows describe a brow that has descended from its natural position. The medical terms are brow ptosis or eyebrow ptosis — “ptosis” simply means drooping.
The brow is held up by the frontalis, the broad sheet of muscle across your forehead. It is the only muscle that lifts the brow. Pulling against it are three depressor muscles — corrugator, procerus and the upper fibres of orbicularis oculi — which pull the brow down and inward. Brow position is the balance between them, plus the elasticity of the skin holding everything in place.
That balance is worth understanding before any treatment, because it explains both how a brow lift works and why anti-wrinkle injections can either raise the brow or drop it depending entirely on where they are placed — covered in detail below.
When skin laxity increases or that muscular balance shifts, the brow drops. The brow, the upper eyelid and the eyelid skin sit in one continuous unit, so a low brow makes the eyelid look heavier even when the eyelid itself is completely normal.
Signs of drooping eyebrows
- Low eyebrows sitting close to or on the upper lash line
- A hooded or heavy upper eyelid, with less visible lid space — though hooded eyes can also occur with a perfectly normal brow position
- A tired, cross or sad expression that doesn’t match how you feel
- Horizontal forehead lines from constantly raising the brows to compensate
- Brow ache or forehead ache, particularly late in the day
- Difficulty applying eye makeup — the lid space disappears when your eyes are open
- Restricted upper vision in more pronounced cases
- Uneven or asymmetrical eyebrows, since the two sides rarely descend equally — one part of broader facial asymmetry
That forehead-line symptom is worth dwelling on. Many people treat the lines and the droopy brows as two separate concerns. They are usually one: the lines exist because the frontalis is working overtime to hold the brow up.
Why droopy eyebrows bother people
The brow is the most expressive part of the face. It is how we signal surprise, concern, scepticism and warmth — so when it descends, the expression it broadcasts stops matching the person behind it. Patients frequently describe being asked whether they are tired, upset or annoyed when they feel none of those things, and finding that mismatch wearing over time.
There is a practical dimension too. Where the brow restricts the upper visual field, people quietly stop doing things — driving at night, reading for long stretches — often without connecting the two. That is worth raising at consultation, because it changes the conversation from cosmetic preference to function.
Brow ptosis, eyelid ptosis or hooding? A self-test
This is the single most useful thing on this page. Getting it wrong is the most common reason people are disappointed by upper-face surgery.
- Look straight ahead in a mirror, face relaxed. Don’t raise your brows — people do this unconsciously, so it may take a moment.
- Find your brow relative to the bony rim above your eye socket. Feel for that ridge with a fingertip. If your brow sits below it, that points to brow ptosis.
- Now hold your brow up gently with a finger, at the position it should sit. If the heaviness largely disappears, your problem is mainly the brow. If a fold of skin still hangs over the lid, there is an eyelid component too.
- Look at your lid margin — the line the lashes come from. If it covers part of your pupil, you also have eyelid ptosis, which is a different operation again.
The three possibilities:
- Brow ptosis — the brow has dropped. Needs a brow lift.
- Eyelid ptosis — the lid margin has dropped. Needs ptosis repair. See our guide to droopy eyelids.
- Dermatochalasis (hooding) — brow and lid margin are fine, but there’s excess skin. Needs upper eyelid surgery. See hooded eyes.
Plenty of people have two or all three at once, which is exactly why an in-person assessment beats a self-test. But knowing which question is being asked makes the consultation far more useful.
Where should your eyebrow sit?
There is a broad aesthetic convention rather than a rule. In women, the brow typically arches slightly above the bony orbital rim, with the peak sitting roughly over the outer part of the iris. In men, it sits lower and flatter, on the rim itself.
That difference matters surgically. Over-elevating a male brow, or placing the arch peak too far towards the centre, produces the surprised or startled look that gives brow surgery a bad name. Restoring your own natural position is the goal, not importing someone else’s.
Eyebrow bone anatomy: how the brow ridge affects brow position
The eyebrow bone is the supraorbital ridge, the curved edge of the frontal bone that forms the roof of each eye socket. The eyebrow rests on a cushion of fat over this ridge, held up by frontalis above. Frontalis does not reach the outer third of the brow, which is one reason the tail of the eyebrow is usually the first part to drop.
Behind the central ridge sits the frontal sinus, an air space that varies a great deal in size between people. A large sinus pushes the front wall of the bone forward and creates a prominent brow ridge, usually more marked in men. A heavy ridge can make normally positioned eyebrows look low and the eyes deep-set, and it changes what surgery can achieve: a brow lift moves soft tissue, not bone.
Ageing alters the picture as well. Comparing patients with photographs taken in their late teens or early twenties, a 2008 study in the Journal of Oral and Maxillofacial Surgery ↗ concluded that the main changes of periorbital ageing reflect volume loss more than gravity[1]. The fat over the ridge deflates, so the brow sits lower and the bone shows more.
Where the bone itself is the issue, it can be reshaped. A 2025 review in Annals of Plastic Surgery ↗ describes burring a mildly prominent ridge and setting back the front wall of a large frontal sinus, with high satisfaction and low complication rates[2]. Our guide to reducing the brow bone explains the options, and brow bone augmentation can be considered after surgeon assessment where a flat ridge leaves the brow poorly supported.
What causes droopy eyebrows?
Ageing and skin laxity
The most common cause. Collagen and elastin decline from the mid-twenties onwards, and forehead skin gradually loses the ability to hold the brow in position. Descent is usually gradual and often more pronounced at the outer third of the brow, which is why the tail of the eyebrow tends to drop first.
Genetics
Brow position is substantially inherited. Some people simply have naturally low-set eyebrows in their twenties, with no ageing involved. This is worth knowing, because a naturally low brow that has always been low is a different conversation from one that has descended.
Sun damage and smoking
Both accelerate the breakdown of collagen and elastin. Cumulative UV exposure is one of the most modifiable contributors to how quickly the upper face descends.
Significant weight loss
Facial fat volume contributes to soft-tissue support. Rapid or substantial weight loss can leave the upper face looking deflated and the brow lower — increasingly seen following GLP-1 medication weight loss.
Years of eyebrow shaping
Decades of waxing, threading and plucking are sometimes cited as a cause of sagging eyebrows, on the basis that repeatedly pulling at thin brow skin stretches it over time. The evidence for this is weak — it is a plausible mechanism rather than a demonstrated one, and it is almost certainly a minor contributor next to ageing and sun exposure. Worth knowing about, not worth worrying about.
Anti-wrinkle injections placed too low
This is the cause most guides omit, and it is increasingly common.
Frontalis is the only muscle lifting your brow. Anti-wrinkle injections treat forehead lines by relaxing frontalis. Relax too much of it, or place it too low, and the brow loses its support and drops — sometimes noticeably.
This produces a frustrating cycle: forehead lines are treated, the brow drops, the upper lids look heavier, and the patient concludes they need eyelid surgery when what they actually need is for the injections to be placed differently.
This is not anecdotal. A randomised controlled trial published in Plastic and Reconstructive Surgery compared three forehead injection patterns in 45 patients and found that injecting the middle of the forehead lowered the eyebrow significantly more than injecting the upper forehead — and concluded that upper forehead injections were less effective on forehead lines but prevented eyebrow ptosis (Jabbour et al., 2018 ↗)[3].
A separate anatomical study in the same journal identified why. Mapping forehead skin movement in 27 volunteers, the authors found the forehead moves in two directions at once: the lower forehead travels upward while the upper forehead travels downward, meeting at a horizontal boundary they termed the line of convergence, sitting at roughly 61% of forehead height. Injecting above that line, they concluded, mitigates the risk of neuromodulator-induced brow ptosis (Cotofana et al., 2020 ↗)[4].
Injection depth matters too. A randomised trial in Dermatologic Surgery found brow position dropped at two and four weeks after intramuscular forehead injection, but was preserved throughout follow-up when the same dose was given intradermally (Kim et al., 2020 ↗)[5].
The practical upshot: a dropped brow after forehead treatment reflects where and how deep the product went, not bad luck. It is avoidable with correct technique — treating the depressors alongside frontalis, staying high on the forehead, and using conservative doses in anyone whose brow is already low. It also resolves on its own as the effect wears off over three to four months. If your droopy eyebrows appeared within a few weeks of forehead injections, that is very likely the explanation, and surgery is not the answer.
Nerve weakness
A brow that drops on one side only, particularly suddenly, is different. This can indicate facial palsy affecting the nerve that supplies frontalis, and needs medical assessment rather than a cosmetic consultation — urgently if it came on over hours and is accompanied by facial or limb weakness or slurred speech. Neuromuscular conditions such as myasthenia gravis can also cause drooping that fluctuates through the day.
How to lift eyebrows without surgery
This is one of the most searched questions on the topic, and it has a genuinely mixed answer rather than a flat no.
Muscle-relaxing injections — a real, modest lift
This is the one non-surgical option with a real mechanism behind it. By relaxing the depressor muscles that pull the brow down — while leaving frontalis free to lift — a skilled injector can produce a genuine elevation of roughly two to four millimetres, with the effect strongest at the brow tail.
That is a modest but visible change, and for mild droopy eyebrows in someone not ready for surgery, it can be exactly right. Effects appear within one to two weeks and last three to four months.
The same technique, done poorly, causes the problem described above. This is a procedure where injector skill matters far more than product. See anti-wrinkle injections and our guide to whether you can get an eyebrow lift without surgery.
Dermal fillers
Volume placed in the temple or along the brow bone can provide a small amount of structural support and indirect lift. Best suited to patients whose upper face has lost volume rather than those with significant skin laxity. See dermal fillers.
Energy-based skin tightening
Radiofrequency and similar devices can improve skin quality and produce mild tightening. Expect subtle improvement in texture and firmness rather than repositioning of the brow. Honest expectation-setting matters here — these are not a substitute for surgery in moderate to severe brow ptosis.
What doesn’t work
- Eyebrow exercises — no evidence. Repeatedly contracting frontalis does not shorten lax skin, and may deepen forehead lines.
- Firming creams and serums — improve surface hydration and texture. They do not lift a brow.
- Brow tapes and lifting strips — a cosmetic, temporary illusion for a few hours.
- Facial massage or gua sha — pleasant, may reduce puffiness. No lasting effect on brow position.
How to fix droopy eyebrows: surgical options
A brow lift — also called an eyebrow lift or forehead lift — repositions the brow and releases the tissues holding it down. Several techniques exist, and the right one depends on your anatomy, hairline and the degree of descent.
Endoscopic brow lift
The most commonly performed technique at Centre for Surgery. Several short incisions are made behind the hairline and a small camera guides release and repositioning of the brow tissues. Scars are hidden in the hair, recovery is quicker than open techniques, and the whole brow can be elevated. See endoscopic brow lift and how it compares in endoscopic vs traditional brow lift.
Temporal (lateral) brow lift
A more targeted procedure addressing the outer third of the brow, through a smaller incision in the temporal hairline. Ideal where the brow tail has dropped but the central brow is well positioned — the commonest pattern. See temporal brow lift.
Gliding brow lift
A minimally invasive technique repositioning the brow through very small access points. See gliding brow lift.
Direct brow lift
The incision sits immediately above the eyebrow itself, and excess skin is removed directly. It gives precise, powerful control over brow height and is particularly useful in older patients with deep forehead lines to hide the scar in, in men with receding hairlines where hairline-based approaches are difficult, and in one-sided brow drop from nerve weakness. The trade-off is a visible scar above the brow, so it is chosen deliberately rather than as a default.
Coronal and hairline brow lift
Open techniques giving the most powerful correction and the greatest control over hairline position. A hairline (pretrichial) lift can shorten a high forehead at the same time, which an endoscopic lift cannot — see forehead lift surgery.
Brow lift with upper eyelid surgery
Where both brow and eyelid contribute, combining a brow lift with upper blepharoplasty gives the most complete result in one recovery. Sequence matters: the brow is lifted first, then any remaining excess eyelid skin assessed — because lifting the brow itself takes up some of that skin. Removing eyelid skin first, then lifting the brow, risks leaving too little skin for the eye to close properly. Our comparison of brow lift vs blepharoplasty covers how the decision is made.
Brow lift recovery
Most patients take 10 to 14 days off work. Bruising and swelling peak around days two to three and can track down into the eyelids. Numbness across the forehead and scalp is normal and settles over weeks to a few months. Sleep propped up for the first week, and avoid strenuous exercise, swimming and saunas for four weeks.
Results settle over three to six months as swelling resolves and tissues soften. Our brow lift recovery guide covers the timeline in detail.
How long does a brow lift last?
Typically 10 years or more. Ageing continues, so gradual change over that period is expected, but a well-executed brow lift is a long-lasting correction rather than a temporary one.
What does treatment for droopy eyebrows cost?
Cost depends on the technique and whether it is combined with eyelid surgery, so a single figure would be misleading. Our brow lift cost guide sets out current prices by technique and what each quote includes, and if eyelid surgery is part of the plan, the blepharoplasty cost guide covers that side. Your exact quote is confirmed in writing after an in-person consultation, and finance is available, subject to status.
Frequently asked questions
How do you fix droopy eyebrows?
It depends what has dropped. A low brow needs a brow lift — endoscopic, temporal, gliding, coronal or hairline depending on your anatomy. Excess eyelid skin needs upper blepharoplasty. A dropped eyelid margin needs ptosis repair. For mild, brow-driven cases, muscle-relaxing injections placed into the depressor muscles give a modest temporary lift.
What causes drooping eyebrows?
Most commonly ageing and skin laxity, with genetics, sun damage, smoking and significant weight loss contributing. Anti-wrinkle injections placed too low in the forehead are an increasingly common and entirely reversible cause. A one-sided drop, especially a sudden one, can indicate nerve weakness and needs medical assessment.
How to lift eyebrows without surgery?
Muscle-relaxing injections into the depressor muscles are the only non-surgical option with a genuine mechanism, giving roughly two to four millimetres of lift for three to four months. Dermal fillers can add indirect support where volume has been lost. Creams, eyebrow exercises and lifting tapes do not reposition the brow.
Can droopy eyebrows affect vision?
Yes. A low brow pushes tissue down onto the upper eyelid and can restrict the upper visual field. Many people compensate by raising the brows or tilting the head back without realising. If your vision is affected, it is worth being assessed properly.
Why is one eyebrow lower than the other?
Some asymmetry is normal — very few faces have perfectly matched eyebrows, and most people’s have always been slightly uneven. What matters is change. A brow that has recently dropped on one side, particularly with other facial weakness, needs medical assessment rather than cosmetic treatment.
Can anti-wrinkle injections cause droopy eyebrows?
Yes, if placed too low or too heavily in the forehead. Frontalis is the only muscle that lifts the brow, so relaxing too much of it removes that support. It resolves as the effect wears off over three to four months, and is avoidable with correct placement.
At what age do eyebrows start to droop?
There is no set age. Gradual descent typically becomes noticeable from the forties onwards, but naturally low-set brows can be present from your twenties, and significant sun exposure or weight loss can bring it forward.
Do eyebrow exercises work for sagging eyebrows?
No good evidence supports them. Frontalis is not weak from underuse — the supporting skin has become lax, and contracting the muscle does not tighten skin. Repeated forceful brow-raising may deepen forehead lines.
Is a brow lift better than eyelid surgery?
Neither is better — they treat different problems. A brow lift raises a descended brow; blepharoplasty removes excess eyelid skin. Choosing the wrong one produces a poor result, which is why the self-test above and a proper assessment matter.
Will a brow lift make me look surprised?
Not when done properly. That appearance comes from over-elevation or from placing the arch peak too centrally. Modern technique aims to restore your own natural brow position, with male and female positions treated differently.
Why do some people have a prominent brow bone?
Mostly genetics and puberty. The brow ridge grows forward during adolescence as the frontal sinus behind it enlarges, and it typically becomes more prominent in men. Some people simply inherit a larger sinus or thicker bone. A prominent ridge is not harmful, but it can make the eyes look deep-set and the brows lower than they are. It can be reduced surgically when it bothers you; creams, exercises and massage do not change bone.
What is a thyroid eyebrow?
It describes thinning or loss of hair from the outer third of the eyebrow, sometimes called Queen Anne’s sign. It is classically linked with an underactive thyroid, but it is not specific: ageing, years of plucking, eczema and alopecia areata can cause the same pattern. It is a hair problem rather than a droop, as the brow itself stays in the same position. If outer-brow thinning comes with tiredness, weight gain, feeling cold or dry skin, ask your GP for a thyroid blood test before considering cosmetic treatment.
How do you fix ageing eyebrows that have dropped and thinned?
Treat the two problems separately. Position comes first: a temporal brow lift raises a dropped brow tail, the most common pattern with age, while carefully placed muscle-relaxing injections give a smaller, temporary lift. Thinning hair is a separate issue to check with your GP if it is new, and can be disguised with brow pencil or tinting. Avoid over-plucking the lower edge of the brow, which makes it look lower still.
