What is Baby Milia? Causes, Symptoms, and Treatment

Quick Summary

• Milia are small, white or yellow spots that often appear on the eyelids, cheeks, nose, chin, or forehead of a baby and usually aren't harmful.
• The main causes are keratin buildup under the skin or dead skin cells, which are a normal part of a newborn's skin processes, as the skin is still learning to shed.
• No changes in parental feeding habits are required in response to the milia; milk, breastfeeding, and formula, as well as poor hygiene, are not the causes of baby milia.
• Baby milia normally resolve on their own within a few weeks to a few months. The safest treatment is to wash gently with warm water and pat dry.
• Squeezing, scrubbing, acne creams, oils, and home remedies are all unsuitable for parents, and they should seek help from a pediatrician if bumps are red, swollen, painful, infected or persist in an unusual way.
• Milk spots or milia are small white or yellowish spots that commonly occur on a baby's face, often near the eyelids, cheeks, nose, chin, or forehead. At first, they can be alarming, but they are, by and large, harmless and don't need any treatment to heal.
• Milia can occur within a few days or weeks after birth. These bumps are not acne, an allergic reaction, nor a matter of poor hygiene. They are caused by the trapping of small flakes of dead skin or keratin just under the surface of the baby's skin.

What Is Baby Milia?

Baby milia are little, hard, pearl-shaped bumps just beneath the surface of the skin. They are sometimes referred to as "milk spots", but are not related to milk or breastfeeding. Studies show how common they are: one neonatal study reported that 45.2% of newborns had milia, making them among the most common early skin findings in newborns.

Milia are particularly common in newborns because their skin is still maturing, and cell shedding is less efficient than in more mature skin. This can lead to the accumulation of dead skin cells, which may create tiny bumps just below the skin's surface.

Milia on babies usually occur on the:

• Nose
• Cheeks
• Chin
• Forehead
• Eyelids
• Area around the mouth

They do not itch, bleed, or contain any pus; they are usually painless.

What Causes Baby Milia?

Baby milia are due to retention of keratin, a natural skin protein. Small white bumps form when keratin or dead skin cells get trapped under the skin's surface. A study of healthy newborns found that 40% to 50% of babies develop milia, supporting the idea that these little bumps are a natural, expected skin trait in newborns.

Contributing causes include:

1. Immature Newborn Skin

The skin of a newborn baby is still adjusting to the outside world. The skin barrier and a natural exfoliation process are not completely developed, and dead skin cells are more easily lodged under the skin.

In a large-scale study, 95.8% of newborns had at least one identified skin finding, and of these, only 0.1% involved any infectious process, making it clear that the vast majority of newborn skin bumps, including milia, are benign.

2. Blocked Skin Pores

Milia is caused by the skin cells piling up in the small openings on a baby's face during early infancy. Milia are consistently reported as small cysts containing keratin in dermatologic studies and, in this case, are directly related to the mechanism.

3. Natural Skin Development

Milia are often a normal process of maturation in newborn skin. They are not usually a sign of any health problem.

4. Skin Healing After Minor Irritation

Milia can arise after mild skin irritation, friction, or minor healing processes in some babies. But most milia have no known cause and occur naturally.

5. Not Caused by Milk or Diet

Although commonly referred to as "milk spots", baby milia are not related to breast milk, baby formula, or the mother's diet. There is nothing to do with feeding about them - they are a skin condition.

Symptoms of Baby Milia

It's easy to recognize baby milia. The bumps are tiny, smooth, and white or very light yellow.

Common characteristics include:

• Small white or yellow bumps on the skin of the face
• Firm texture, no swelling.
• In most cases no redness around the area.
• No pain, itching, or discomfort
• No fluid, pus, or crusting
• Single, stable-sized bumps that gradually fade over time.

A key difference between milia and baby acne is that milia are white, smooth, and dry, whereas baby acne may be red, inflamed, or pimple-like.

Is Baby Milia Normal?

Yes, baby milia is completely normal and very common in newborns. They are not harmful and don't need treatment in most cases.

Although it can be alarming to see white bumps on your baby's face, milia is a very common and self-limited skin finding. The bumps normally go away as the baby's skin matures and starts to shed dead skin properly.

How Long Does Baby Milia Last?

Milia typically clear up in a few weeks after birth. Sometimes they can take a bit longer to fully clear, but they should fade over time.

Parents should avoid picking, squeezing, or applying any product to the bumps; this is the most important thing parents can do at this time. Gently caring for the skin and allowing it to rest can easily clear milia.

Baby Milia Treatment: What Should Parents Do?

Most cases of baby milia do not need medical intervention. Gently, consistently, and with patience is the safest and most effective way. According to clinical research, milia are considered benign and self-limited, which is a clear indication to treat them gently rather than actively intervene.

1. Wash the Baby’s Face Gently

Wash baby's face every day with warm water and a soft cloth. Do not rub or put pressure on the affected skin.

2. Pat the Skin Dry

Thoroughly dry the skin with a soft towel after cleansing. Never rub or scrub bumps in any way.

3. Avoid Squeezing the Bumps

Do not try to pop, pinch, or squeeze baby milia. This can cause skin irritation, and/or scarring, or infection.

4. Avoid Harsh Skin Products

The skin of a newborn should never be treated with acne creams, exfoliants, scrubs, retinoids, or adult skin care products. These treatments are too harsh on newborn skin.

5. Skip Oils and Heavy Lotions

Heavy ointments, facial oils, and rich creams can clog pores and further irritate sensitive skin. Only use products that are made for newborns and only as directed by your pediatrician.

6. Let the Skin Heal Naturally

Time is just about the best treatment for baby milia. The bumps will fade on their own as the baby's skin matures and the natural shedding process takes place.

What Not to Do for Baby Milia?

Parents should NOT use adult or older child treatments. A baby's skin is very thin and much less tolerant than adult skin, and any well-intentioned intervention can cause harm.

Avoid:

• Squeezing or popping milia (in any way)
• Using acne treatments or spot treatments
• Using exfoliating acids or chemical exfoliants
• Washing a baby's face with cloths or sponges
• Applying steroid creams without specific medical advice
• Consider using home remedies like toothpaste, lemon juice, or vinegar
• Using oily or heavy products on the affected areas

Especially, home remedies can aggravate sensitive baby skin and make parents' problems even worse.

Baby Milia vs Baby Acne

At first glance, baby milia and baby acne may appear the same, but they are different and have different characteristics.

Baby milia are characterized by small white or yellow spots that are usually firm and dry and not surrounded by redness. They are most often found on the nose, cheeks, chin, and forehead.

Baby acne usually manifests itself as red bumps, small pimples, or inflamed whiteheads. It is usually more irritated-looking and may occur on the cheeks, forehead, or scalp.

Most cases of both conditions will resolve on their own. But if your baby's acne seems severe, more inflamed than usual, or doesn't go away within a reasonable period, it's time to see a pediatrician.

When Should You See a Doctor?

Baby milia are virtually always harmless, but a pediatrician should be consulted if:

• The bumps are red, swollen, or painful.
• Any pus, crusting, or bleeding
• Rash seems to be expanding rapidly
• Your baby has a fever in addition to the changes in his/her skin.
• After several months the bumps don't appear to improve
• The area around the bumps appears infected
• Your baby appears uncomfortable, irritable, or bothered
• You're not sure if the spots are milia or another skin rash

A pediatrician can determine if the bumps are milia, baby acne, eczema, heat rash or some other skin disorder that may require different treatment.

Can Baby Milia Be Prevented?

However, it is not always possible to prevent milia in babies, as these are a normal part of newborn skin development. But with some simple, regular care, you can prevent unnecessary aggravation and reduce factors that worsen your skin.

Helpful practices include:

• Preventing your baby's face from getting dirty or wet
• Regularly washing your face with lukewarm water
• Selecting mild, non-fragrant baby soaps
• Not overwashing the skin
• Wearing soft towels and clothes that won't aggravate the skin
• Using products that don't contain heavy oils, greasy creams or occlusion on the face

The idea is not to hurry the milia to go away, but to help and shield the baby's skin as it takes its own time to exfoliate.

Final Thoughts

Baby Milia are harmless, common, and in most cases temporary. They are caused by keratin or dead skin cells being trapped under the baby's developing skin. These small white bumps are not usually painful for a baby and may cause some concern for parents, but they will usually heal without treatment in weeks or months.

The best treatment is gentle, regular care. Gently wash the face with warm water, be careful NOT to squeeze the bumps, and avoid strong creams or home remedies. It is always good to seek advice from your pediatrician if the bumps are getting worse over time, if they are getting red, or if they are causing your baby discomfort or appear infected.

Frequently Asked Questions (FAQs): Baby Milia Causes

1. Is baby milia normal in newborns?

Yes, baby milia are totally normal and very common. The small white bumps frequently observed on a newborn's nose, cheeks, or chin are harmless and usually resolve on their own without intervention.

2. How long does baby milia take to go away?

A baby's milia will usually clear up on its own within a few weeks, although some may last for a few months. This should happen over time, and typically, patience is the only key.

3. Should I pop or squeeze my baby’s milia?

No. Baby milia should not be squeezed, scraped, or picked at, as this can cause sensitivity, redness, infection, or scarring on delicate newborn skin. It is best to keep the bumps in the same condition throughout.

4. Can I use breast milk on baby milia?

No relevant evidence that breast milk clearance of milia has any meaning. Because milia will go away on their own, the best way to care for them is to gently wash with warm water, no home remedies are necessary.

5. Is baby milia the same as baby acne?

The differences between milia and baby acne lie in appearance: milia are typically white or yellow bumps without redness or inflammation, while baby acne is red, pimple-like, or inflamed. If the rash is spreading, red, or visibly irritated, a pediatrician should see it.

6. What can I put on baby milia?

Normally, no medication is required. A mild cleanser, some warm water, and a soft pat to dry is enough. Newborn skin should not be treated with acne creams, exfoliants, facial oils, heavy lotions or adult skin care products.

7. Can milia appear on places other than the face?

Yes, but the most common areas are the nose, cheeks, chin, and forehead. Sometimes milia may occur in other parts of the body, but if a bump is found in an unusual place or doesn't go away after a while, it is best to have a doctor check it out.

8. Why does my baby’s milia look worse when they cry?

Crying temporarily increases blood flow and may make the skin look redder and the small bumps more prominent. It's usually not a problem if the redness fades when your baby is calm.

9. When should I worry about baby milia?

If the bumps are red, swollen, painful, or crusty; if any pus forms; if your baby develops a fever; or if the bumps do not improve or your baby gets more of them after a few months of waiting, see a pediatrician.

10. Can baby milia leave scars?

If left alone, baby milia will generally not cause scarring. Scars are more likely to occur when bumps are squeezed, scratched, and/or repeatedly irritated, which is why gentle, hands-off care is important.
