Those tiny white dots on your baby’s nose are called milia, and they’re one of the most common skin findings in newborns. About half of all full-term babies are born with them. They’re completely harmless, require no treatment, and disappear on their own within a few weeks.
What Milia Actually Are
Each white dot is a tiny cyst sitting just beneath the surface of the skin. Inside, it contains keratin, the same protein that makes up hair and the outer layer of skin. Milia form in the tiny hair follicles that cover a baby’s face. The keratin gets trapped in a small pocket near the surface, creating a firm, pearl-like bump usually about 1 to 2 millimeters across.
The nose is the most common spot, but milia also show up on the cheeks, eyelids, and scalp. Babies can have just a handful or dozens scattered across the face. They aren’t red, swollen, or irritated. They look like small white or yellowish pinpoints and feel slightly raised if you run a finger over them gently.
Why Newborns Get Them
A newborn’s skin is still maturing. The follicles and oil glands are functioning for the first time outside the womb, and keratin can accumulate faster than the skin sheds it. Maternal hormones circulating in the baby’s body also play a role. These hormones stimulate the oil glands on the nose and cheeks, making the follicles slightly more active than they would otherwise be. That combination of immature skin turnover and hormonal stimulation makes milia almost inevitable for a large portion of newborns.
Milia aren’t caused by anything a parent did or didn’t do. They aren’t related to cleanliness, formula versus breastfeeding, or any product used on the baby’s skin.
When They Go Away
Most milia clear up within a few weeks of birth as the baby’s skin matures and begins to shed keratin normally. In some cases they can linger for two to three months, but they resolve without leaving any mark or scar. No treatment speeds up the process, and none is needed.
What Not to Do
It’s tempting to try to squeeze or pick at the bumps, but don’t. A newborn’s skin is far thinner and more fragile than adult skin, and squeezing can cause irritation, broken skin, or infection. Adult acne products, exfoliants, and scrubs should never be used on a baby’s face. Cooking oils or kitchen-sourced products aren’t appropriate either. If your baby’s skin seems dry around the bumps, a gentle emollient formulated and tested specifically for newborns is safe to use, but the milia themselves don’t need any topical treatment.
Similar-Looking Conditions
A few other newborn skin conditions can look similar at first glance, so it helps to know the differences.
Baby acne typically appears two to four weeks after birth rather than being present from day one. It looks like small red or inflamed bumps, sometimes with a white center, and tends to spread across the cheeks, forehead, and chin. Milia, by contrast, are white without any surrounding redness and are present at birth.
Sebaceous hyperplasia is another common finding on a newborn’s nose and cheeks. These are tiny yellowish-white bumps caused by enlarged oil glands responding to maternal hormones. They’re evenly spaced and sit right at the opening of each pore, giving the nose a slightly bumpy texture. Like milia, they’re harmless and fade on their own.
Epstein pearls are essentially the same thing as milia but found inside the mouth, on the gums or the roof of the palate. They’re small white cysts containing keratin, and they resolve without treatment just like the ones on the nose.
Signs That Something Else Is Going On
Milia are never red, warm, weeping, or crusted. If the white bumps on your baby’s face develop surrounding redness, look inflamed, produce any drainage, or appear alongside a fever or other signs that your baby is unwell, a different condition may be at play. Bacterial skin infections in newborns can produce yellow crusts and shallow erosions. Viral or fungal infections can cause blisters or widespread rashes. These presentations look distinctly different from the calm, pearly dots of milia, but if anything about the bumps changes or your baby seems uncomfortable, a pediatrician can quickly tell the difference with a visual exam.
