Milia: leave alone or get them removed?
Tiny pearly white bumps that look like they should pop but won't are usually milia — trapped keratin cysts under the surface of the skin. Answer 8 questions and we'll tell you whether you actually have milia (vs. something that looks similar), whether to leave them alone, and what extraction options are safe for the location you have them in.
Milia are tiny pearly-white cysts of trapped keratin (the protein in skin, nails, and hair) that form just under the surface of the skin — most commonly around the eyes, on the cheeks, and along the forehead. They look like whiteheads but behave nothing like them: they don't have a pore opening, they don't respond to squeezing, and trying to "pop" them at home usually causes scarring without releasing the cyst.
What milia actually are
Milia are small (usually 1-2mm) keratin-filled cysts that develop when dead skin cells get trapped in pockets just below the skin surface. They're not infected, not contagious, and not the same biological structure as acne — which is why acne treatments don't make them go away.
Two broad categories:
- Primary milia: appear spontaneously, with no clear cause. Common in newborns (50% of babies have some — they clear on their own within weeks). In adults, they appear randomly, particularly around the eyes and on the cheeks.
- Secondary milia: form after skin damage — sunburn, blisters, dermabrasion, laser resurfacing, or after using occlusive products like heavy creams, petroleum jelly, or thick sunscreens.
Milia vs. things that look like milia
Several conditions get mistaken for milia. The triage tool below sorts your inputs across the differential:
- Whiteheads (closed comedones): pore-based, soft, can technically be extracted with proper extraction. Milia are closed under skin, hard, dome-shaped.
- Sebaceous hyperplasia: yellow-white with a tiny central dimple, common in adults over 40. Often confused with milia and even with basal cell carcinoma — first-time appearance after 40 warrants a derm visit.
- Syringomas: small flesh-colored or pale yellow bumps that cluster under the eyes. Sweat gland origin. Hereditary. Look very similar to milia but treatment differs.
- Xanthelasma: yellow plaque-like deposits on the eyelids, often associated with elevated cholesterol. Needs internal medicine consult, not just topical treatment.
- Cherry angioma: bright red, blood vessel origin. Different category entirely.
Why you shouldn't squeeze milia at home
Milia don't have a pore opening at the skin surface. The cyst is encapsulated below intact skin. Squeezing creates pressure on the surrounding skin without releasing anything — the cyst stays. What you get instead:
- Bruising and inflammation in the surrounding skin (especially fragile under-eye skin)
- Scarring — visible, sometimes permanent
- Secondary infection if your hands or nails aren't sterile
- Hyperpigmentation — darker skin tones are particularly prone to leaving a darker mark than the original bump
The proper extraction technique requires a sterile lancet to make a tiny break in the overlying skin, then gentle expression. Dermatologists do this in under 5 minutes per lesion. Even aestheticians need specific training and proper tools — and they shouldn't work around the eye area.
How milia clear on their own (or don't)
- Newborn milia: clear spontaneously within 2-4 weeks. Do nothing.
- Primary milia in older children: often clear within months.
- Adult primary milia: less likely to resolve. Months to years if untreated.
- Secondary milia after skin damage: may resolve once the underlying skin condition heals — but stubborn ones persist.
Treatment options when they don't clear
- Dermatology extraction with sterile lancet: the gold standard. 5-10 minutes, minimal discomfort, no scarring when done correctly. Some derms call this "milia extraction" or "cyst express." Often covered by insurance if multiple lesions or symptomatic.
- Topical retinoids (adapalene 0.1% OTC, tretinoin 0.025-0.05% Rx): increase cell turnover, can soften milia over 8-12 weeks. The slowest path but the only non-procedural option.
- Chemical exfoliation: low-strength glycolic or salicylic acid can help, but won't extract the cyst itself.
- Electrocautery or curettage: for stubborn or large milia. Quick in-office procedure.
- Cryotherapy: rarely used for milia, and never on darker skin tones (Fitzpatrick V-VI) due to permanent hypopigmentation risk.
Prevention
If you keep developing milia, look at your routine:
- Heavy occlusive eye creams are the most common adult-milia cause. Switch to lighter, water-based serums under the eyes.
- Petroleum jelly or Aquaphor overnight on the face. Same problem.
- Heavy mineral sunscreens with thick texture. Switch to lighter chemical or fluid mineral formulations.
- Sun damage (the underlying skin damage type that breeds secondary milia). Daily SPF, year-round.
- Mild regular exfoliation: a low-strength AHA 2-3x per week helps prevent keratin trapping.
When to see a dermatologist
- The bumps are around or on the eyelids (sensitive area, needs sterile procedure)
- You're seeing more bumps appear over months
- The bumps are spreading or changing
- First-time appearance after age 40 (rule out sebaceous hyperplasia masquerading as milia)
- You're already on a retinoid for 12+ weeks without improvement
- You want them gone faster than the topical route can deliver
Common questions about milia
Can I pop milia at home?
No — and trying causes the most common milia-related skin damage. Milia don't have a pore opening; the cyst is encapsulated below intact skin. Squeezing creates bruising, inflammation, and often scarring without releasing the cyst. Proper extraction requires a sterile lancet to break the surface skin, then gentle expression — a 5-minute office procedure with no scarring when done correctly.
How do I get rid of milia naturally?
The two evidence-based "natural" routes: (1) topical retinoid (adapalene 0.1% OTC) applied nightly for 8-12 weeks increases cell turnover and softens existing milia while preventing new ones; (2) mild AHA exfoliation 2-3x weekly. There's no DIY extraction method that doesn't risk scarring. For newborns and young children, the answer is patience — most resolve spontaneously within weeks to months.
What causes milia in adults?
The most common cause: heavy occlusive products around the eyes — thick eye creams, petroleum jelly overnight, occlusive sunscreens. Other causes: skin damage from sunburn or laser treatments (which produce secondary milia), retinoid initiation in some people, and genetic predisposition. Some adults develop primary milia spontaneously with no clear cause.
Are milia the same as whiteheads?
No. Whiteheads are closed comedones — clogged pores with a visible opening and soft contents. Milia are deeper, harder, encapsulated keratin cysts with no pore connection. Whiteheads respond to acne treatments (salicylic acid, benzoyl peroxide); milia don't. The diagnostic difference: a whitehead has a tiny head you could conceivably pop; milia look like solid white domes with no opening.
How much does milia removal cost?
Dermatology in-office extraction typically runs $50-200 per session in the US, with some insurance coverage if lesions are symptomatic or numerous. Aesthetician extraction (where legal) is usually $50-100. The cost of treating a scar from at-home extraction is far higher. For multiple lesions, a single derm visit can clear most of them at once.
Will milia go away on their own?
Newborn milia: almost always, within 2-4 weeks. Older children: usually within months. Adults: less likely. Adult primary milia can persist for months to years without intervention. Secondary milia (after skin damage) sometimes resolve as the underlying skin heals, but stubborn ones persist. If they're cosmetically bothersome and haven't moved in 8-12 weeks of a retinoid, a dermatology visit for extraction is the fastest path.
