Acne vs Milia

Milia are tiny, firm white bumps that sit just under the surface of the skin, most often around the eyes. Each one is a small pocket of trapped keratin with no opening, which is why squeezing does nothing and why a professional can remove one in seconds.

What is it?

Acne
Milia
What is it?

It starts in the follicle.
Acne affects the hair follicle and its oil gland.

Spots take several forms.
Plugs form blackheads or whiteheads; inflammation forms pimples and deeper lumps.

It is not about dirt.
Bacteria are only one part of the process.

Tests are rarely needed.
An unusual pattern or hormonal symptoms may call for assessment.

Overview
Oil and dead skin cells block hair follicles. This can cause blackheads, whiteheads, pimples, or deeper painful lumps.

They are tiny cysts.
Milia contain keratin just beneath the skin surface.

They look like white bumps.
They are firm and pearly, often on the eyelids or cheeks.

They are harmless.
Milia are different from acne whiteheads.

Unusual bumps need a check.
Inflamed, widespread or persistent bumps may need assessment.

Skin tones
Inflamed acne on light skin. The spots sit in a patch of pink, and the ring of redness around each one is easy to see. A few have a yellow-white head, and the skin between them is dry and flaking.
Acne on medium skin. Raised pink-red spots across the cheek and jaw, some with white heads, alongside flat brown marks left behind by spots that have already cleared.
Acne on brown skin. Active spots read as brown-purple rather than red, which makes the inflammation easy to underestimate. Flat dark marks from older spots cover as much of the area as the raised spots do.
Acne on deep skin. The active bumps look darker and slightly purple rather than red, and the flat dark marks left behind by earlier spots are the most obvious thing in the photo.

In the skin

Oil and shed skin cells can block a hair follicle, changing the environment inside the pore. Bacterial activity and the immune response contribute to inflammation, swelling and tender spots.

Milia are tiny cysts that trap keratin, a normal skin protein, just beneath the surface. The enclosed keratin makes a firm pale bump rather than an inflamed acne spot.

Milia. Can occur at any age and are especially common in newborns.

Causes and triggers

Causes

Acne forms when oil and dead skin cells clog pores, acne bacteria grow inside them, and inflammation follows. Hormones that increase oil play a central role.

Oil and dead skin cells block hair follicles. Bacteria within the follicles and inflammation contribute to pimples and deeper spots. Hormonal changes can increase oil production.

Milia form when keratin, a skin protein, gets trapped in a tiny pocket just under the surface. They can appear on their own or after skin damage.

Family tendency

Acne often runs in families. A parent with severe acne raises the chance of severe acne.

Acne can run in families. A close relative with deep, painful acne increases the chance of developing that pattern.

Daily Care

Acne
Milia
Daily care

Habits that help

  • Strip the routine back
    Use a gentle cleanser, moisturizer and sunscreen without unnecessary product layers.
  • Cut back on sugar and refined carbs
    Helps a little, mostly in oily, hormonal acne.
  • Wear sunscreen daily
    Stops dark marks from deepening.

Avoid

  • Avoid: Picking and squeezing
    The biggest cause of avoidable scars.
  • Avoid: Scrubbing and over-washing
    Strips the barrier and pushes you off treatment.
  • Avoid: Adding more products
    Avoid adding several irritating products at the same time.
  • Avoid: Heavy oil-based hair products
    Cause stubborn small bumps along the hairline.
  • Avoid: Friction and trapped sweat
    Straps and collars press oil into pores.
  • Avoid: Heat and humidity
    Swell the pore lining and trap what is behind it.
  • Avoid: High-glycemic diet
    Sugar and refined carbs raise the hormones driving oil.
  • Avoid: Skim milk and whey protein
    Linked to acne more than other dairy, though weakly.
  • Avoid: Stress
    Raises the hormones that worsen acne you already have.
  • Avoid: Stopping treatment once it works
    Acne usually returns within two to three months.

Habits that help

  • A lighter product around the eyes
    Low cost, low risk, uncertain benefit.
  • Daily sunscreen
    Keeps any mark after extraction from darkening.
  • Professional extraction
    A tiny nick lifts the pearl out whole.
  • A gentle chemical exfoliant
    Salicylic or low-strength glycolic acid keeps ducts clearer.
  • Treating the cause in secondary milia
    Stops new ones forming; extraction alone does not.

Avoid

  • Avoid: Squeezing them
    No opening — pressure only bruises and marks the skin.
  • Avoid: Picking with fingernails
    Risks infection, a scar or a dark mark.
  • Avoid: Using a needle on yourself at home
    Unsterile and hard to aim near the eye.
  • Avoid: Scrubs, brushes and grainy exfoliants
    Abrading the surface cannot reach the sac.
  • Avoid: Pore strips and extraction tools
    Nothing to grip — there is no opening.
  • Avoid: Repeated injury to the same area
    Each healing episode can seal off another fragment.
  • Avoid: Aggressive resurfacing
    Deep peels, dermabrasion and ablative lasers are triggers.
  • Avoid: Heavy occlusive balms in one spot
    Worth changing if milia keep forming there.
  • Avoid: Waiting for cleansers to fix it
    Cleansing cannot reach a sealed sac.

Treatment differences

Evidence labels come from each condition’s own treatment list.

Treatment
● Acne
● Milia
Filter by type
Acne type

Select one or more.

All types
Over-the-counter
Five adapalene gel 0.1% tubes and boxes lined up on white, including Differin, Effaclar, PanOxyl and Neutrogena

Adapalene

Strong evidence

The strongest thing you can buy without a prescription, and the best first move for most acne. It unclogs pores before they inflame, which is why it prevents spots rather than treating them.

Three acne wash tubes on white: Differin Deep Cleanser, CeraVe Acne Foaming Cream Cleanser and PanOxyl

Benzoyl Peroxide

Strong evidence

Kills the bacteria involved in inflamed spots, and is the one thing that stops acne bacteria becoming resistant to antibiotics. Lower strengths work about as well as higher ones and sting less. It bleaches towels and pillowcases.

Five azelaic acid tubes and bottles on white, most marked 10 percent, from Peach Slices, Paula's Choice, Facetheory, The Ordinary and Naturium

Azelaic Acid

Moderate evidence

Works on the spot and the mark it leaves at the same time, which makes it useful on deeper skin tones. It is also one of the few acne treatments considered safe in pregnancy.

Paula's Choice 2% BHA exfoliant, La Roche-Posay Effaclar cleanser and a CeraVe psoriasis cream pump

Salicylic Acid

Moderate evidence

Gets inside the pore and loosens the plug, so it suits blackheads and whiteheads more than deep spots. Gentler than a retinoid, and weaker than one.

Six niacinamide products on white, including The Ordinary 10% + Zinc 1%, Paula's Choice Booster and EltaMD UV Clear

Niacinamide

Limited evidence

Sold heavily for acne, and the evidence for clearing spots is thin. It is genuinely useful for the marks left behind and for tolerating stronger actives - just not as the treatment itself.

Four sulfur acne products: Kate Somerville EradiKate, De La Cruz 10% sulfur ointment, The Ordinary and Thayers

Sulfur

Limited evidence

An old treatment, usually a mask or a spot dab, that dries the surface of a spot and mildly loosens plugs. It is gentle enough for skin that cannot tolerate benzoyl peroxide or a retinoid. It smells, and it is weaker than everything above it on this list.

Five dark glass tea tree essential oil bottles with glass droppers and one green box on white

Tea Tree Oil

Limited evidence

A 5 percent gel reduces inflamed spots in small studies, more slowly than benzoyl peroxide does. Neat oil straight from the bottle is a common cause of an itchy rash, so buy it already diluted. It is a reasonable extra rather than something to build a routine on.

Five adapalene gel 0.1% tubes and boxes lined up on white, including Differin, Effaclar, PanOxyl and Neutrogena

Adapalene

Limited evidence

The over-the-counter retinoid, used at night. It speeds up how the duct lining sheds, which over two to three months lowers how many new milia form. It will not open or empty the ones you already have, because nothing applied to intact skin can reach a sealed sac. Start a few nights a week, and keep it off the eyelids themselves. Ask your doctor about it if you are pregnant or trying to become pregnant.

Paula's Choice 2% BHA exfoliant, La Roche-Posay Effaclar cleanser and a CeraVe psoriasis cream pump

Salicylic Acid

Limited evidence

A gentle leave-on exfoliant that helps keep small ducts clear, which is prevention rather than treatment. It does nothing to a milium that has already sealed over. Low strength, a few times a week, and not on eyelid skin, which is thin and irritates easily.

Existing Dermapedia illustration of scrubs, brushes and pore strips.

Scrubs, brushes and pore strips

Avoid

These are what most people try first, and they cannot work. A scrub abrades the surface, and the sac sits under an intact surface. A pore strip needs an opening to grip, and a milium has none. What scrubbing does achieve is irritation, which is not neutral here, because repeated injury to one area can seal off new ducts.

A lighter cream around the eyes

A lighter cream around the eyes

Listed

Thick eye creams and balms get blamed for milia constantly. The evidence is weak and plenty of people get milia while using nothing at all, so this is not a reliable fix and it will not clear the bumps already there. If you keep getting them in the exact spot where a heavy product sits, switching to something lighter costs nothing and is worth trying.

Four glycolic acid toner and liquid bottles lined up on white, one with its box

Glycolic Acid

Limited evidence

Keeps the surface layer shedding evenly, on the same prevention logic as salicylic acid. Low strength only. Strong glycolic peels are the opposite of helpful here — deep peeling is one of the recognized causes of milia in the first place.

Prescription topicals
Tretinoin — Header Image

Tretinoin

Strong evidence

The most studied topical in acne. Stronger than adapalene and more irritating with it, so it is usually the step up rather than the starting point. Not used in pregnancy.

A white plastic tube lying on its side on a white background, cap to the left, labeled Trifarotene in teal lettering with a pale green swoosh curving beneath the word.

Aklief

Strong evidence

A newer retinoid, and the one specifically tested on chest and back acne rather than just the face. Useful when the trunk is the main problem. Expensive without coverage.

A white metal tube lying at an angle on a white background, white ribbed cap to the left, labeled Clindamycin in black lettering with a teal swoosh curving beneath the word.

Clindamycin

Strong evidence

Calms inflamed spots, but should never be used on its own. Guidelines are explicit about this - alone it stops working within months as bacteria adapt, so it is always paired with benzoyl peroxide or a retinoid.

Tazarotene — Header Image

Tazarotene

Strong evidence

The strongest of the prescription retinoids, and the step to take when tretinoin has stopped making a difference. It is particularly good on stubborn blackheads and whiteheads. It is also the most irritating of them, so it is usually started two or three nights a week. Not used in pregnancy.

Winlevi — Header Image

Winlevi

Moderate evidence

Blocks the hormone signal that drives oil production, but only where you put it. It is the first hormonal option that works topically, and the only one that can be used by men as well as women.

Aczone — Header Image

Aczone

Moderate evidence

Mild on the skin and tends to suit adult women with inflamed spots who cannot tolerate a retinoid. Applied at the same time as benzoyl peroxide it can temporarily stain skin orange, so space them apart.

Tretinoin — Header Image

Tretinoin

Limited evidence

The prescription-strength version of the same idea as adapalene, used at night when there are many milia or they keep coming back. Over two to three months it reduces how many new ones form. It does not clear the existing bumps, and it is used carefully near the eyes. Ask your doctor about it if you are pregnant or trying to become pregnant.

Prescription pills
An amber prescription bottle lying on its side on a white background with a plain white label reading Doxycycline, and six small round white tablets spilled out in front of it.

Doxycycline

Strong evidence

Brings widespread inflamed acne down quickly, and is meant to be used for three to four months, not indefinitely. Always alongside a topical, which is what carries on once the tablets stop.

Accutane

Strong evidence

The only acne treatment that often produces lasting clearance after the course ends. What it costs you is months of dry lips and skin, blood tests, and strict pregnancy prevention. For acne that scars, that trade is usually worth making early rather than late.

Spironolactone — Header Image

Spironolactone

Moderate evidence

For the pattern rather than the individual spot - deep jawline acne in adult women that flares with the cycle. It works slowly, over three to six months, and can be continued long term. Not used in pregnancy.

An illustrative blister pack and white sleeve labeled Birth Control Pills.

Birth Control Pills

Moderate evidence

Lowers the hormone signal driving oil production across the whole body, so it suits acne on the chest and back as well as the face. Takes about three months to show, and carries a small clot risk that needs weighing up.

16:9 hero for Minocycline. Never cropped: the tone strip and the corner logo depend on the full frame.

Minocycline

Moderate evidence

Another tetracycline antibiotic for widespread inflamed acne, used the same way as doxycycline: three to four months, always alongside a topical. It is usually kept as the second choice, because it carries rarer but more serious side effects, including a blue-gray skin discoloration with long use.

Seysara shown in recognizable oral medication carton or bottle matching the reference packaging, with three beige oval tablets beside it.

Seysara

Moderate evidence

A narrow-spectrum antibiotic designed specifically for acne, so it disturbs gut bacteria less than doxycycline. One tablet a day, still meant for three to four months and still alongside a topical. It works about as well rather than better, and it is considerably more expensive.

None listed
Injections
Editorial illustration for Cortisone Injection, based on the entry’s treatment or equipment reference.

Cortisone Injection

Limited evidence

Deals with one stubborn painful lump, not the condition. It settles in a day or two and is the safe alternative to squeezing it. It does nothing to prevent the next one.

None listed
Procedures
Editorial illustration for Comedone Extraction, based on the entry’s treatment or equipment reference.

Comedone Extraction

Limited evidence

Clears blackheads that are already there, quickly and visibly. It does not stop new ones forming, so it is an add-on to a retinoid rather than a substitute for one.

Editorial illustration for Chemical Peel, based on the entry’s treatment or equipment reference.

Chemical Peel

Limited evidence

Modest benefit for clogged pores and a better one for the dark marks left behind. Needs repeat sessions, and the benefit fades if the daily treatment stops.

Editorial illustration for 1726 nm Laser, based on the entry’s treatment or equipment reference.

1726 nm Laser

Limited evidence

Heats the oil glands themselves, which is a genuinely different approach from everything else on this page. Trial results out to about six months are good, it works across skin tones, and it is expensive and rarely covered. Long-term data is still limited.

Editorial illustration for Photodynamic Therapy, based on the entry’s treatment or equipment reference.

Photodynamic Therapy

Limited evidence

Can help stubborn inflamed acne, but the protocols vary widely between clinics, the downtime is real, and the evidence is not strong enough to put it ahead of the options above.

Editorial illustration for Blue Light Therapy, based on the entry’s treatment or equipment reference.

Blue Light Therapy

Limited evidence

Blue light kills acne bacteria at the surface, so a course can quiet mild inflamed spots for a while. The effect fades within weeks of stopping, and it does nothing for blackheads or deep lumps. In-clinic courses cost far more than a topical that would do more.

Editorial illustration for Comedone Extraction, based on the entry’s treatment or equipment reference.

Comedone Extraction

Moderate evidence

The definitive treatment, and the only thing that actually empties a milium. The roof is nicked with a sterile blade or needle and light pressure lifts the keratin pearl out whole, in about ten seconds a bump. The one that is removed does not come back in that spot. Done once, properly, it heals in a few days; repeated digging at the same place is what leaves marks.

Editorial illustration for Electrodesiccation and Curettage, based on the entry’s treatment or equipment reference.

Electrodesiccation and Curettage

Limited evidence

A fine heated needle used to destroy the sac, usually kept for milia that are numerous, very small, or sitting somewhere awkward for a blade. It works. It is also more likely than a simple nick to leave a small mark, so it is not the first choice for one or two bumps on an eyelid.

Editorial illustration for Cryotherapy, based on the entry’s treatment or equipment reference.

Cryotherapy

Limited evidence

Freezing is sometimes offered for milia. It is less precise than extraction, more uncomfortable, and on deeper skin tones it carries a real risk of leaving a pale or dark mark where the bump was. There is little reason to choose it over opening the sac and lifting the contents out.

Outlook

Long term

Acne is usually controlled rather than permanently cured. Treatment reduces new breakouts, but improvement takes time and maintenance may be needed. Deep or scarring acne deserves early assessment because existing scars may remain after the active spots settle.

The course depends almost entirely on age: in a newborn the bumps clear themselves, and in an adult they sit still. Milia that follow an injury or procedure appear one to two months after the skin healed and often clear over several months, though they can be extracted sooner.

Complications

Possible complications
  • Dark marks
  • Redness
  • Scars
  • Depression and anxiety
  • Family conflict
  • Social impact
More details

Dark marks
Flat brown or violet patches left where a spot was. They are not scars and they do fade, but it commonly takes 6 - 12 months, and sun exposure makes them last longer. These WILL FADE with time.

Redness
Flat pink or red marks left where a spot was, most often on lighter skin. Also not scars. They usually settle on their own, though it can take several months. These WILL FADE with time.

Scars
Permanent dents, pits or raised bumps left where inflammation broke down the skin's structure. Once formed, they can only be improved by procedures. These WILL NOT FADE with time.

Depression and anxiety
Acne can affect self-esteem, confidence and mental health. The link is consistent, and it does not track with how severe the acne looks to anyone else - which is itself a reason to treat it.

Family conflict
This is very common. Acne visits involving a teenager and a parent can sometimes be challenging, particularly when there is ongoing conflict about acne care.

Social impact
People may avoid photos, dating, social situations or activities because of their skin.

  • Gone from that spot for good
More details

Gone from that spot for good
An emptied milium does not return there. New ones can form nearby — a new bump, not a recurrence.

When to get help

When to get help

Seek help for painful deep spots, scarring, persistent breakouts, or an uncertain diagnosis. Earlier treatment can reduce the chance of more scars.

Do not assume eye symptoms are part of acne. They need their own assessment.

Ask a clinician about persistent or troublesome bumps, especially near the eyes. Avoid trying to pierce or extract them yourself.

Common questions

Acne:Does acne ever go away?

For most people it settles by the mid-twenties. About one in six women still has it into her 30s and 40s, and it can return after pregnancy, after stopping the pill, or with any hormone shift. Controlled rather than cured.

Acne:Does what I eat cause acne?

Less than the internet suggests. The evidence points at high-glycemic diets - sugar and refined carbohydrate - and, less consistently, at skim milk. Chocolate and greasy food never held up, and no diet replaces treating the skin.

Acne:Why does my skin get worse when I start a new treatment?

That is purging. Retinoids speed up clogs already forming under the surface, so weeks of spots arrive at once. It peaks around weeks two to six and settles by week eight. Still worsening past 10 to 12 weeks is irritation, not purging.

Acne:Is it ever okay to pop a spot?

No. Squeezing pushes the contents sideways into surrounding skin, turning a spot that would have gone in days into a mark that lasts months, or a scar that lasts forever. A large, painful lump can be injected in clinic instead, and settles in a day or two.

Acne:Do I need antibiotics?

Sometimes, but never alone and never for long. They go alongside benzoyl peroxide or a retinoid, usually for three to four months, then stop while the topical carries on. Alone or indefinitely, they stop working and drive resistance.

Acne:Is my acne hormonal?

Almost all acne is hormonal - hormones drive oil production. The label only matters if it changes treatment: deep spots along the jawline and lower face in an adult woman, flaring before periods, usually respond better to hormonal treatment than to antibiotics.

Milia:Why will they not pop?

Because there is no pore. A milium is a sealed sac of keratin under intact skin, so nothing has a route out. Pressure sends the contents sideways into the tissue, which is how bruising and dark marks happen. Open the roof first and it comes out.

Milia:Can I get rid of them at home?

You can reduce how many new ones form, with a retinoid at night over two to three months. You cannot reliably remove the ones you have, and please do not try with a needle - eyelid skin is thin, the aim is difficult, and the usual result is a mark that outlasts the bump.

Milia:Does extraction hurt or leave a scar?

A brief scratch rather than real pain; most people need no anesthetic. One small nick and light pressure heals in a few days without a scar. Repeated digging at the same spot is what leaves marks.

Milia:Will they come back?

The one removed does not return. New ones can form elsewhere, especially if you are prone to them or something is triggering them — a blistering condition, a resurfacing procedure, steroid cream. That is a new bump, not a recurrence.

Milia:My newborn has white bumps on the nose. What should I do?

Nothing. Newborn milia are common and clear within a few weeks as the ducts finish maturing. No creams, no rubbing, no special washing. If they are still there after a couple of months, or the baby has widespread bumps with fragile or blistering skin, have them looked at.

Milia:I got them after a laser treatment. Is that normal?

Yes. Milia are a recognized consequence of laser resurfacing, dermabrasion and deep peels, usually a month or two after the skin heals. They often settle over several months, and can be extracted any time if they bother you.
