Quick Summary
- Milia are small, firm, white or yellowish cysts caused by trapped keratin just under the skin's surface — most common around the eyes, cheeks, and nose.
- Whiteheads are a type of acne caused by a clogged pore with oil and dead skin trapped beneath a thin layer of skin.
- Milia are firmer and don't have a visible pore opening; whiteheads sit within a pore and are often slightly softer.
- Milia cannot be extracted the way whiteheads can — squeezing doesn't work since there's no open pore to release the contents.
- Milia are common in newborns (where they resolve on their own) and adults (where they may need professional extraction).
Milia and whiteheads both show up as tiny white bumps on the skin, especially around the face, and they're routinely mixed up — but milia aren't actually a form of acne at all, and the standard whitehead approach (squeezing) simply doesn't work on them.
What Milia Are
Milia are small, firm cysts that form when keratin — a protein found in skin, hair, and nails — becomes trapped just beneath the surface of the skin instead of shedding normally. They appear as tiny, hard, white or pale yellow bumps, most commonly around the eyes, cheeks, eyelids, and nose. Unlike whiteheads, milia have no visible pore opening on the surface, which is exactly why they can't be popped or extracted the way a whitehead can — there's simply no exit point for the trapped material. Milia are extremely common in newborns (where they resolve on their own within weeks) and also common in adults, sometimes linked to sun damage, skin injury, or certain heavy skincare products.
What Whiteheads Are
Whiteheads are a type of acne lesion — a closed comedone — that forms when a hair follicle becomes clogged with oil and dead skin cells, with a thin layer of skin closing over the top. Unlike blackheads, the trapped material doesn't oxidize and darken, so it stays white or flesh-colored. Whiteheads sit within an actual pore and, while extraction should ideally be done properly (not squeezed at home, which risks scarring or worsening inflammation), they are tied to the pore and oil-gland system the way milia are not.
Key Differences at a Glance
| Feature | Milia | Whiteheads |
|---|---|---|
| What it is | Trapped keratin cyst | Clogged pore (closed comedone) |
| Firmness | Firm, hard to the touch | Slightly softer |
| Pore opening | None | Present, just closed over by skin |
| Common locations | Around eyes, cheeks, nose | Face, chest, back — typical acne zones |
| Extractable by squeezing? | No | Can be, though professional extraction is safer |
Why Acne Products Don't Clear Milia
Because milia aren't caused by oil or clogged pores the way whiteheads are, typical acne treatments — benzoyl peroxide, salicylic acid washes — generally don't resolve them, though gentle exfoliation can sometimes help prevent new ones from forming. Persistent milia usually need a small, precise extraction procedure done in-office, where a fine tool is used to nick the overlying skin and release the trapped keratin.

If small white bumps around the eyes or face aren't going away with gentle skincare and aren't responding like typical whiteheads, they're likely milia — a quick in-office extraction is a simple, effective fix rather than continuing to try acne products that won't work on them.
