Milia: The White Bumps No Scrub Will Remove

Milia are tiny keratin cysts sealed beneath the skin, with no opening to the surface, which is why scrubs, acids, and squeezing usually fail to remove them. They are harmless, painless, and very common. Clearing one usually means a clinician opening it with a sterile lancet and lifting the core out.

What are milia, exactly?

A milium is a small cyst filled with keratin, the structural protein of the outer skin. The plural is milia. One bump is a milium.

They look like firm white or yellowish domes, usually a millimeter or two across. They do not redden. They do not drain. They do not hurt.

Microscopically, they are cysts. A 2026 pediatric overview of milia en plaque describes epidermal cysts containing keratin within the dermis. Inflammatory infiltrate around those cysts is minimal (Nowowiejska-Purpurowicz et al., 2026).

Note what that describes. A walled off pocket of keratin, sitting below the surface, surrounded by intact skin. The obstacle is the wall.

Two things milia are not. They are not clogged pores, and they are not a sign of poor cleansing. Nothing about washing frequency changes a cyst that sits under intact skin.

Why scrubs and acids do not remove milia

A milium is a closed sac. Its wall is a layer of epithelium, and the keratin is packed behind that wall.

Surface exfoliants work on the outermost dead layer of skin. AHAs, BHAs, and PHAs loosen those cells. Loosening surface cells does not open a cyst wall underneath them.

Time behaves the same way. Normal skin cell turnover pushes cells outward and sheds them. It has no mechanism for emptying a sealed compartment below the surface.

Now compare a comedone. A comedone forms inside a hair follicle, and a follicle has an opening at the skin surface. Its contents have a route out. That is why extraction and topical actives can help there. Our pore science page covers that anatomy.

Milia have no such route. That single structural fact explains why so many routines aimed at them go nowhere.

It also explains a familiar cycle. People treat milia as though they were closed comedones and escalate the actives. The skin gets irritated. The white bumps are still there six weeks later.

Steaming, hot cloths, and suction tools run into the same wall. They can soften the surface. They cannot create an exit that does not exist.

Primary and secondary milia: what is the difference?

A 2008 review in the Journal of the American Academy of Dermatology set out an updated classification. The authors noted that few studies had examined where milia come from. No comprehensive review existed before theirs (Berk and Bayliss, 2008).

The working split is primary versus secondary.

Primary milia appear in skin with no identifiable preceding injury. Neonatal milia sit in this group.

Secondary milia follow damage. Blisters, burns, trauma, resurfacing procedures, and certain drugs all appear in the case literature.

Form	Typical setting	What the literature reports
Primary milia	Otherwise healthy facial skin, often around the eyes	A 2026 overview describes neonatal and primary milia as transient, in contrast to the plaque form (source)
Milia en plaque	White papules sitting on a raised red plaque	The same overview classes it as an uncommon variant of primary milia. In its series of six children, every case followed trauma and appeared 2 to 6 months later, most often on the knee (source)
Secondary milia after blistering disease	Bullous pemphigoid and other blistering conditions	Milia were recorded in 8 of 102 bullous pemphigoid patients, or 7.8%, in a Brazilian chart review (source)
Secondary milia after procedures	CO2 laser resurfacing performed for premalignant and malignant skin lesions	Acneiform lesions and milia, counted together as one category, were among the most common problems in a 105 patient series. The series logged 11 problems and 2 complications in total (source). Milia also appear in an earlier review of laser resurfacing complications (source)
Drug associated milia	Reported during systemic retinoid therapy	A 2026 case report describes roughly 20 milia on the upper cheeks after two months of oral isotretinoin at 30 mg daily (source)

One row in that table looks like a contradiction, so it is worth naming. Milia en plaque is filed as a variant of primary milia. Yet all six children in the pediatric series developed it after an injury.

Both statements come from the same paper. The primary label there describes what the lesion is, meaning keratin cysts distributed across a plaque. It is not a statement about what caused it.

The classification matters for one practical reason. If your milia are secondary, the trigger is often findable. A dermatologist is the person who can find it.

Note the timing in the pediatric plaque series. The lesions did not appear at the moment of injury. They showed up months afterward, which makes the connection easy to miss.

Why milia are easiest to notice under the eyes

The skin below the lower eyelid is thin. A cyst sitting just beneath it shows through as an obvious white dot. The same cyst on the back would be easy to miss.

That region shows up repeatedly in the case literature. The 2026 isotretinoin report describes tiny white dome shaped papules on the upper cheeks. They sat mainly below the lower eyelids (AlQaydi and AlMarzouqi, 2026).

The 2026 pediatric overview lists reported sites for milia en plaque. They include the periorbital area, the retroauricular region, and the cheeks (source).

Visibility is not the same as frequency. None of these reports establishes that milia form more often under the eyes than elsewhere. They establish that the area comes up often in published descriptions.

The practical point is about consequences, not counts. Skin there is thin and it moves constantly. A mark left behind in that spot is hard to hide.

How to get rid of milia: what removal actually involves

Removal is mechanical. The cyst has no opening, so one has to be made.

The standard approach is a small nick over the cyst with a sterile lancet or needle. The keratin core is then expressed gently through that opening.

Technique notes published for dermatologists describe several ways to make and clear that opening (Haller et al., 2023). Those notes are written for clinicians working with sterile instruments.

Outcomes can be clean. In the isotretinoin case above, the milia were managed with simple manual extraction. They resolved completely without recurrence, and the drug was continued (source).

For milia en plaque, the 2026 overview lists four reported options: topical retinoids, curettage or manual extraction, CO2 or Er:YAG laser, and observation. Selection depends on lesion size, location, and the child's tolerance for intervention (source).

None of that is a home project. Three reasons.

First, diagnosis. Several unrelated conditions look like milia, and some need a different response entirely.

Second, sterility and depth. You are making a break in the skin barrier, often within a centimeter of the eye.

Third, scarring and pigment change. Digging at a cyst with fingernails can leave a mark. That mark can outlast the bump by years.

See a board-certified dermatologist. This is a short, low drama visit for them, and it is the correct route.

Milia in newborns: how common are they?

Very common, and unrelated to anything a parent did.

One caution about the numbers below. Only the Iranian study reported a rate for milia specifically. The other two counted skin lesions of every kind, which is a different measure entirely.

Study population	Newborns examined	Any skin lesion	Milia specifically
Iran, first three days of life (Firouzi et al., 2020)	1,202	958 newborns, or 79.8%	45.2%
Hungary, first 72 hours (Abraham et al., 2017)	4,658	74.35% had at least one skin manifestation	Not reported separately
Germany, 12 to 120 hours old (Lorenz et al., 2000)	1,000	59.7% had one or more skin lesions	No figure published

The German team did comment on their milia count. They noted it came in below other published series, without stating a number (source).

That is a useful caution to carry. A single prevalence figure from one hospital population is not a fixed rate for all newborns.

Neonatal milia are described as transient (source). Persistent or unusual bumps in an infant are a question for a pediatrician or pediatric dermatologist. They are not a skincare problem.

Can you prevent milia?

The evidence here is thin. Pretending otherwise would be dishonest.

The 2008 classification review stated plainly that few studies had examined the origin of milia (Berk and Bayliss, 2008). The mechanism of primary milia is not well characterized. A prevention protocol built on top of it is not well supported either.

What the literature does support is narrower. Specific events are associated with secondary milia: blistering disease, ablative resurfacing, trauma, and at least one systemic retinoid. Those associations are documented in the sources cited above.

Common advice to avoid rich eye creams, or to exfoliate more often, is not backed by trial evidence. It may well be harmless. It is not proven, and it should not be sold to you as proven.

If your milia followed a procedure or a medication, tell the treating clinician. That is a conversation, not a product swap.

Milia versus other white bumps

Identification changes what you should do next. It is also the part people most often get wrong.

What it is	How it presents	Key structural difference
Milium	Firm white or yellow dome, does not drain	Keratin cyst with no opening to the surface
Closed comedone	Skin colored or white bump, softer, can become inflamed	Plugged hair follicle, so a follicular opening exists
Sebaceous filament	Grey or tan dots, mostly on the nose	Normal follicular content, not a lesion at all
Syringoma	Small yellowish papules, often around the eyes	Described on dermoscopy as translucent papules without cystic structures (source)
Molluscum contagiosum	Dome shaped papules, often in clusters	Shows central umbilication and a cheesy plug on dermoscopy (source)

Dermoscopy is what makes that table usable in a clinic. In the 2026 pediatric series, milia en plaque looked consistent across the cases with dermoscopy available. Those showed pearl white globules on a pink background (source).

That kind of pattern recognition is exactly what a visit buys you. It is not available to you in a bathroom mirror.

Some bumps are part of a broader roughness rather than discrete cysts. Our guide to uneven skin texture covers that separate problem.

Should you use a microneedling device on milia?

No. Do not use a home device on milia.

A milium is a diagnosis. It needs a clinician to confirm it and to remove it. That is the whole answer, and nothing about a home routine changes it.

There is a second reason for caution. Ablative resurfacing procedures are documented as being followed by milia in some patients (source, source). In this literature, procedures sit on the causal side of secondary milia rather than the treatment side.

Two of our guides cover the caution side of home devices in general. Read who should not microneedle and microneedling under the eyes. Active or undiagnosed lesions belong in the first category.

When should you see a dermatologist about milia?

Any white bump you cannot confidently identify is worth a look. That is the general rule, and it covers most cases.

A few situations move it up the list.

Bumps that grow, change color, bleed, or crust over are not behaving like milia. Get those assessed promptly.

White papules sitting on a raised red plaque fit the milia en plaque pattern rather than ordinary milia. That variant is described as persistent rather than self resolving (source).

A crop of new bumps appearing at once, particularly after starting a medication, is worth reporting. The isotretinoin case report is one documented example of that timing (source).

Bumps on the eyelid margin need professional handling regardless of what they turn out to be.

The visit itself is usually brief. Expect an examination, often with dermoscopy, and a diagnosis. Where removal is appropriate, it can frequently happen in the same appointment.

FAQ

Can you pop milia at home?

You should not. A milium has no opening, so squeezing pushes on intact skin and releases nothing. Removing one means making a small opening with a sterile instrument. That is a clinical procedure. Fingernails or an unsterile tool risk infection and scarring. Near the eye, pigment change can outlast the bump.

Do milia go away on their own?

Sometimes. Neonatal milia are described in the literature as transient. Milia en plaque, by contrast, is described as slow growing and persistent without spontaneous resolution. For ordinary adult milia there is no reliable timeline to promise. If a bump has been unchanged for months, get it looked at rather than waiting longer.

What is the difference between milia and whiteheads?

Structure. A whitehead is a closed comedone, meaning a plugged hair follicle. A follicle has an opening at the skin surface. A milium is a keratin cyst with no such opening. That is why extraction and topical actives can help comedones. The same approach usually does nothing at all for milia.

Does retinol get rid of milia?

The evidence is limited. In the 2026 pediatric milia en plaque series, two of six children were given a topical retinoid. Two others were given topical salicylic acid. The remaining two were simply observed. That is a small case series, not a trial, and it concerns one uncommon variant. Ask a dermatologist first.

Why do I keep getting milia under my eyes?

Thin skin in that area makes small cysts easy to see, so recurrence there is noticeable. Repeated milia can also be secondary, following blistering, trauma, resurfacing, or a medication. One 2026 report links eruptive milia to oral isotretinoin. A dermatologist can look for a trigger, which is more useful than cycling through products.

Are milia ever a sign of something more serious?

Usually not. Milia themselves are benign. The 2008 classification review does highlight rare variants, including milia associated with genetic skin disorders. Widespread, eruptive, or plaque forming milia deserve medical assessment. So do milia alongside other symptoms. That is a reason to book an appointment, not a reason to worry in advance.
