Milia are the small, firm, pearly white bumps that appear most often around the eyes, on the cheeks and across the nose. They sit just under the surface of the skin, they do not have an opening, and they will not respond to squeezing. That last point is where most of the damage gets done.
They are harmless. The reason people want them gone is cosmetic, and that is a perfectly reasonable thing to want addressed. Understanding what they actually are makes it much clearer why some approaches work and most home remedies do not.
What milia actually are
A milium is a tiny cyst filled with keratin, the structural protein that makes up the outer layer of skin, hair and nails. Dead skin cells that would normally shed become trapped in a small pocket beneath the surface, and the keratin they contain hardens into a compact ball.
This is why they behave so differently from spots. Acne and whiteheads involve oil and bacteria in a blocked follicle, and the follicle has an opening to the surface. If your bumps turn out to be acne rather than trapped keratin, the treatment path is completely different.
A milium has no opening at all. There is nothing to squeeze out, which is why pressing on one moves it around without releasing anything.
- Firm rather than soft, and they do not flatten under pressure
- Uniformly white or pale yellow, without the redness that surrounds inflamed acne
- Usually 1 to 2 millimetres across and consistent in size
- Not painful or itchy
- Persistent, often unchanged for months or years
Why they form
Dermatology distinguishes between two situations, and the difference matters for what you do next.
Primary milia arise on their own without any obvious trigger. In adults they tend to appear around the eyes and on the cheeks, and they often persist rather than clearing on their own.
Secondary milia follow something that disrupted the skin. Common precursors include burns including sunburn, blistering conditions, prolonged use of heavy occlusive products, and healing after a skin injury or some resurfacing procedures. Where skin has been damaged, the normal shedding process can be interrupted and keratin becomes trapped.
Certain topical medications can also trigger secondary milia. Prolonged use of potent prescription anti-inflammatory creams thins the outer skin layer and disrupts the normal shedding cycle, creating the conditions for keratin to become trapped. If you notice milia forming in an area where you have been applying a prescribed topical medication, it is worth raising with the prescribing doctor rather than stopping the treatment on your own.
Cumulative sun exposure is a recognised contributor, which is relevant in South Australia given the UV levels through much of the year. Long-term damage thickens the outer layer of skin and makes trapping more likely.
If you are noticing milia alongside broader signs of sun damage, our article on how laser treatment helps sun-damaged skin covers the wider picture.
Where they form on the face
The face accounts for the vast majority of milia that people notice. The cheeks and the bridge of the nose are the most common sites after the eye area, and bumps on the chin and forehead are not unusual. On the nose they tend to cluster across the bridge and around the nostrils, while on the chin they often sit just below the lower lip where the skin is relatively thin.
The distribution does not follow the oily T-zone pattern you see with acne. Milia form wherever dead skin cells become trapped, which can happen in drier areas just as easily. That is part of why acne products designed for oil control do nothing for them.
Why milia are so common around the eyes
Under the lower lash line, across the upper eyelid and at the outer corners: milia turn up here more than anywhere else on the body. Small white bumps under the eyes are one of the most common presentations.
The skin here is among the thinnest on the body, with very few oil glands and a slower rate of cell turnover. That combination makes keratin trapping more likely. Heavy eye creams and concealers make it worse. Occlusive products sitting on skin that already sheds poorly is a reliable trigger.
People often ask whether milia on the eyelid can be removed. They can, but the thin skin and proximity to the eye itself mean this is not the place for home attempts with a needle. In clinic, the same sterile lancet technique is used with additional care around the lid margin. For milia right at the lash line, a practitioner experienced with the area is the appropriate choice.
If you have persistent milia around your eyes and live in Adelaide, a consultation at the Kent Town clinic can help confirm whether they are milia rather than something like syringomas, which look similar in that area, and determine the right approach from there.
Why squeezing does not work
Because there is no pore or opening, pressure has nowhere to push the contents. What it does instead is damage the surrounding tissue. People frequently arrive at a clinic with more marking from months of picking than from the milia themselves.
- Bruising and prolonged redness in the area worked on
- Broken capillaries, especially in the thin skin around the eyes
- Introduced infection from unsterile fingernails or tools
- Post-inflammatory pigmentation that can outlast the original bump by months
- Scarring, which is a lasting trade for a temporary cosmetic concern
If picking has already left dark marks, pigmentation removal treatments may help once the area has settled, though results depend on the type and depth of discolouration. Preventing further damage is always the better path.
The same applies to comedone extractors bought online. The tool is not the problem; the absence of an opening is.
The skin around the eyes deserves particular caution, and that is exactly where milia most often turn up. It is roughly a quarter the thickness of skin elsewhere on the face, sits over a dense network of fine blood vessels, and marks easily. Damage there is both more likely and more visible, and it takes longer to settle.
There is also the question of what you are actually looking at. Several unrelated conditions produce small bumps in the same locations, and some of them respond badly to being interfered with. Attempting removal before knowing which one you have is a reasonable way to turn a cosmetic issue into a clinical one.
| Milia | Whiteheads | |
|---|---|---|
| Contents | Trapped keratin | Oil and bacteria |
| Opening to surface | None | Yes, a blocked follicle |
| Feel | Firm, does not flatten | Softer, compressible |
| Responds to squeezing | No | Sometimes, though not advised |
| Usual treatment | Sterile lancet extraction | Topical acne management |
How they are removed in clinic
The usual approach is a small procedure done in the consulting room. A very fine sterile needle or lancet is used to create a small opening in the skin over the cyst, and the keratin core is then lifted out with gentle pressure or a small extractor. Each one is dealt with individually, and several can be treated in a single appointment.
Most people describe a brief sharp sensation rather than significant pain, and anaesthetic is not usually required. Afterwards there may be small pink marks for a day or two. Because the opening created is deliberate, controlled and sterile, the risk profile is quite different from doing it yourself.
Where milia are numerous or particularly stubborn, other approaches such as light electrosurgery or a resurfacing treatment may be discussed instead. CO2 laser resurfacing is one option sometimes considered for widespread milia alongside broader skin texture concerns, though it involves more recovery time than extraction alone. Chemical peels are another resurfacing option, particularly where improving overall skin texture is also a goal.
You can read more about how this is handled at our Kent Town clinic on our milia removal in Adelaide page.
Milia have no opening to the surface. That single fact explains why squeezing, extractor tools and steam achieve nothing except risk of marking the skin.
What about home treatments
Exfoliating acids are the one category with a plausible rationale. Products containing salicylic acid or glycolic acid increase skin cell turnover, which over time may help prevent new milia forming and occasionally helps very superficial ones work their way out.
Realistically, they will not clear established milia. The cyst sits below the surface within intact skin, and a topical product cannot reach it. Expect prevention rather than removal, and give any regimen a couple of months before judging it.
Prescription vitamin A creams work along similar lines but are stronger. They speed up the rate at which the outer skin layer renews itself, which may help prevent new milia from forming in people who are prone to them. A GP can assess whether one is worth trying. They take several weeks to show any effect, they make the skin noticeably more sensitive to UV, and they are not suitable during pregnancy, so they need to be discussed rather than self-prescribed.
Steam, scrubs, toothpaste and pin-based kits sold for extraction do not work and carry the same injury risks as squeezing. Some skin conditions and treatments make aggressive exfoliation a poor idea, so check with a practitioner before adding acids if you have reactive skin.
Reducing the chance of new ones
A few practical habits reduce the chance of new milia forming.
- Daily broad spectrum sun protection, since UV damage is a contributing factor
- Lighter products around the eyes, where heavy occlusive creams are a common trigger
- Gentle regular exfoliation appropriate to your skin type rather than aggressive scrubbing
- Removing makeup properly, particularly heavy eye products
- Treating any underlying condition that damages the skin barrier
Several other conditions produce small bumps in the same places and are regularly mistaken for milia.
- Sebaceous hyperplasia, soft yellowish bumps with a small central dimple
- Syringomas, firm skin-coloured bumps clustered under the eyes
- Xanthelasma, soft yellow plaques near the inner eyelid
- Closed comedones, which look similar but sit in a blocked follicle
Each is managed differently. That is the practical reason to have bumps identified rather than assumed.
How long treatment takes and what it costs
Most people want to know two things before they call: how long they will be in the chair, and what they are up for. A typical milia appointment runs 15 to 30 minutes depending on how many are being treated.
Pricing is listed on our pricing page and depends on the number treated. Those figures are indicative and confirmed at consultation once we have seen what you have.
Many people combine the appointment with something else they were already considering, since the extraction itself takes little time.
When to have something looked at
Milia are benign, so there is no medical urgency. That said, several other things can look similar, including sebaceous hyperplasia, syringomas, xanthelasma and some early skin lesions. A bump that grows, changes colour, bleeds, or behaves differently from the others is worth having assessed rather than assumed.
Any procedure carries risk, including infection, pigment change and scarring, and outcomes vary between individuals. Assessment by a registered health practitioner is the only way to confirm what you are dealing with and whether removal suits you. General information on skin lumps is available from healthdirect’s page on milia.

Common questions
Will milia go away on their own?
Adult milia often persist for months or years. Many do not resolve without intervention, which is the usual reason people end up having them removed.
Are milia a sign of high cholesterol?
No. That association belongs to xanthelasma, which are soft yellowish plaques usually near the inner eyelid and can relate to lipid levels. Milia are keratin cysts and carry no such link, but if you are unsure which you have, get it looked at.
Do they come back after removal?
The one removed does not return, but new milia can form if the underlying tendency or trigger remains. People prone to them often have occasional maintenance appointments.
Can milia be removed from the eyelid?
The area around the eyes is where they most commonly appear and where the skin is thinnest, so it needs care and is a particularly poor place to attempt anything yourself.
How many can be treated at once?
Several are commonly addressed in one appointment. Where there are a great many, treatment may be staged so the skin is not overworked in a single session.
What causes milia in adults?
Primary milia in adults form when dead skin cells become trapped under the surface with no obvious cause. Unlike neonatal milia in newborns, which typically clear on their own within a few weeks, adult milia tend to persist. Secondary milia in adults follow a clear trigger: sun damage, skin injuries, blistering conditions, or prolonged use of heavy occlusive products.
Are milia itchy?
Milia are not normally itchy or painful. If the bumps you are noticing do itch, they may be something else entirely: closed comedones, a mild dermatitis, or another condition that looks similar. That is worth mentioning when you have them assessed.
Why do I keep getting milia?
Some people are simply more prone to them. Ongoing triggers such as heavy skincare products around the eyes, cumulative sun damage, or incomplete exfoliation mean the conditions for keratin trapping stay in place even after existing milia are removed. A sudden cluster can follow a change in skincare products, a period of heavy sun exposure, or a skin procedure. Adjusting products and maintaining sun protection can reduce how often new ones appear, but may not prevent them entirely.
Can retinol help with milia?
Over-the-counter retinol and prescription vitamin A creams increase the rate at which skin cells turn over, which may help prevent new milia from forming by keeping dead cells from building up under the surface. They are unlikely to clear an established milium that has already hardened into a cyst. A GP can advise whether a prescription-strength option suits your situation, keeping in mind that these creams increase sun sensitivity and are not suitable during pregnancy.
Do certain medications cause milia?
They can. Prolonged use of potent topical prescription anti-inflammatory creams can be a trigger, particularly on the face. These medications thin the outer skin layer and disrupt the normal shedding cycle, creating the conditions for keratin to become trapped. If milia appear in an area where you have been applying a prescribed topical medication, mention it to the prescribing doctor rather than stopping the treatment yourself.
The short version
Milia are trapped keratin, not blocked pores, which is why squeezing achieves nothing except risk. Removal is an in-clinic procedure using a sterile lancet.
Topical acids may help prevent new ones but will not clear existing cysts. If they bother you, an assessment will confirm what they are and what is sensible from there.
If you want the bumps identified and dealt with properly rather than picked at, an assessment is the next step. Book a consultation at our Kent Town clinic in Adelaide, or call the clinic on (08) 8239 0431 to talk it through first.
