The Bottom Line

Milia are tiny white or yellowish pearly bumps that appear on the face of about 40–50% of newborns. They are completely harmless, require no treatment, and go away on their own within 3–4 weeks. Do not squeeze or pick them — this can irritate your baby's delicate skin. Simply wait, and they will disappear without leaving any mark.

What Are Milia?

Milia (singular: milium) are tiny cysts — small pockets filled with a protein called keratin — that form just beneath the surface of a newborn's skin. Their name comes from the Latin word for "millet," the tiny grain they resemble. Under the skin, they look like miniature pearls.

They appear in 40–50% of healthy newborns, making them one of the most common skin findings in the first weeks of life. Milia are not a rash, not an infection, and not a sign that anything is wrong with your baby. They are simply a feature of normal newborn skin development.

What Do Milia Look Like?

Here is what you will see:

  • Very small bumps — typically 1–2 millimeters across (about the size of a pinhead)
  • White to pale yellow in color, with a slightly pearly sheen
  • Firm to the touch, not soft or squishy
  • No surrounding redness, swelling, or irritation
  • Most common on the nose, cheeks, forehead, and chin — though they can appear on the lips, scalp, or elsewhere on the face
  • Often appear in small clusters, not just a single bump

Milia do not itch, hurt, or bother your baby in any way.

Why Do Newborns Get Milia?

Milia form when tiny amounts of keratin (the protein that makes up the outer layer of skin, nails, and hair) become trapped within small pockets in the developing skin. In the womb, the skin's microscopic oil glands and pores are still maturing. Keratin can get stuck before those tiny channels fully open. Once the skin matures after birth, the channels open and the keratin releases — and the milia disappear.

Milia are not caused by poor hygiene. Washing your baby's face differently will not prevent or treat them. They are simply a normal part of newborn skin development.

How Are Milia Different from Other Newborn Bumps?

Several other normal newborn skin findings can look similar to milia. Here is how to tell them apart:

  • Erythema toxicum: Red blotchy areas with a white or yellow center; milia have no surrounding redness
  • Baby acne (neonatal acne): Small red pimples, sometimes with whiteheads; tends to appear at 2–4 weeks and involves surrounding redness
  • Sebaceous gland hyperplasia: Tiny yellowish bumps specifically on the nose from maternal hormones; fades quickly on its own
  • Neonatal herpes: Fluid-filled blisters (vesicles), not firm white papules; often accompanied by systemic illness — if you are unsure, contact your doctor

The key distinction for milia: firm, white, no redness, no fluid, no fever, no distress in the baby.

What Happens to Milia Over Time?

Milia resolve completely on their own without any treatment:

  • Most milia start to disappear in the first 2–4 weeks of life
  • By 1–2 months of age, virtually all neonatal milia are gone
  • They leave no scars, no discoloration, and no lasting mark of any kind

What Should You Do (and Not Do)?

Do:

  • Wash your baby's face gently with warm water and a soft cloth as part of normal care
  • Leave the milia alone to resolve on their own
  • Mention them at your baby's next well-child visit if you have any questions

Do not:

  • Squeeze, pop, or pick the bumps — this can break the skin, cause pain, risk infection, and potentially leave a small scar
  • Apply creams, lotions, or over-the-counter acne products — these do not help and may irritate newborn skin
  • Scrub the face harder than normal — this will not speed up resolution

When to See a Doctor

  • The bumps are surrounded by redness or look inflamed
  • Your baby seems uncomfortable, fussy, or shows other signs of illness
  • The bumps contain visible fluid or are weeping
  • The bumps have not fully resolved by 3 months of age
  • You are unsure whether what you are seeing is milia or something else

Frequently Asked Questions

Are milia harmful to my baby?

No, not at all. Milia are completely benign. They are one of the most common normal findings in newborns and do not indicate any health problem. Your baby feels nothing from them.

Can I speed up how fast milia go away?

No. There is nothing that speeds up the resolution of neonatal milia. The bumps disappear as your baby's skin naturally matures. Any attempt to manipulate them — squeezing, rubbing with a cloth, or applying products — risks causing more harm than good.

My baby has dozens of them — is that normal?

Yes. Some babies have just a few milia; others have many. The number of milia does not indicate any health problem or say anything about your baby's overall condition. All will resolve at the same rate.

Can older children or adults get milia?

Yes. Milia can occur at any age — in older children and adults, they often arise from sun damage, certain skincare products, or after skin injuries. Adult milia can sometimes be removed by a dermatologist if they don't resolve on their own.
