 Milia, also known as milk spots, are tiny white bumps that commonly appear on newborns’ skin. These harmless bumps are caused by trapped keratin, a protein found in the skin. While milia may be unsightly, they are not a cause for concern and typically disappear on their own within a few weeks or months.

In this blog post, we’ll delve into the causes of milia in newborns, explore safe remedies for alleviating their appearance, and discuss professional treatment options if necessary. So, if you’re a concerned parent seeking answers about these common newborn skin bumps, read on!

What is milia?

 Milia, often affectionately referred to as “milk spots,” are common skin occurrences that parents might notice on their newborn’s face, particularly around the nose, cheeks, and chin. These small, raised bumps can raise questions and concerns for new parents. To understand milia in newborns better, it’s essential to delve into what they are, why they appear, and how to manage them. These cysts typically contain a protein called keratin. Here’s a closer look at Milia:

  • Appearance: Milia manifests as small, raised bumps on the skin. They usually appear white or yellowish and can resemble tiny pearls or beads. Because of their unique appearance, they are often called “milk spots.”
  • Painless: The good news is that milia are generally painless. They don’t cause discomfort to the baby, making them primarily a cosmetic concern.
  • Harmless: Milia, importantly, are harmless and usually resolve on their own without the need for medical intervention. They are a temporary and benign condition in most cases.

Types of Milia in Newborns

When it comes to milia in newborns, not all cases are the same. There are different types of milia, each with its unique characteristics and causes. Understanding these variations is essential for parents to recognize and manage the specific type of milia their newborn might have. Here’s an overview of the common types:

1. Neonatal Milia:Neonatal milia are the most common type in newborns. They appear as small, pearly-white or yellowish bumps on a baby’s face, typically around the nose, cheeks, and chin.

  • Cause: These milia develop due to the presence of tiny skin flakes or dead skin cells getting trapped near the surface of the skin.
  • Duration: Neonatal milia usually appear shortly after birth and tend to resolve on their own within a few weeks or months. They are benign and do not cause discomfort to the baby.

2. Milia En Plaque: Milia en plaque is a less common type but can affect newborns. Unlike neonatal milia, they present as larger, raised, and grouped patches of milia. These patches can be found on the face, neck, and upper body.

  • Cause: Milia en plaque might be associated with an underlying skin condition or genetic factors.
  • Duration: Unlike neonatal milia, milia en plaque may persist for a more extended period and could require medical evaluation and treatment.

3. Primary Milia: Primary milia are similar in appearance to neonatal milia, appearing as small, pearly-white or yellowish cysts. They can occur in both newborns and adults.

  • Cause: Primary milia often arise due to factors like blocked sweat ducts or skin trauma.
  • Duration: In newborns, primary milia typically resolve on their own without any specific treatment, similar to neonatal milia.

4. Milia in Premature Babies Premature infants can also develop milia. Their appearance is similar to neonatal milia.

  • Cause: Premature infants may experience delayed skin development, making them more susceptible to milia.
  • Duration: Milia in premature babies usually disappear as the baby’s skin matures and develops.

Understanding these different types of milia is essential because it helps parents distinguish between common, harmless milia and rarer forms that might require medical attention. Most cases of milia in newborns are transient and benign, disappearing as the baby’s skin matures. However, if parents have concerns about the type or persistence of milia on their baby’s skin, it’s always wise to consult with a healthcare professional for proper evaluation and guidance.

Causes of Milia in Newborns

Milia, those tiny, pearly-white or yellowish bumps that often appear on a newborn’s face, can raise questions about why they develop. Understanding the causes of milia in newborns is important for parents to provide the best care and address any concerns. Here’s an exploration of the factors behind the occurrence of milia in infants:

Blocked Sweat Glands: One of the most common causes of milia in newborns is blocked sweat glands. These tiny glands on the skin produce sweat, but in some cases, they can become obstructed. Newborns have developing skin, and their sweat glands may not be fully mature. When sweat glands become blocked, it can trap sweat and skin cells, leading to the formation of milia.

Hormonal Changes: Hormonal changes in a newborn’s body can contribute to the development of milia. This is often linked to an increase in maternal hormones passed to the baby during pregnancy.

Maternal hormones can stimulate the oil glands on the baby’s skin. This increased oil production can lead to the formation of milia. The hormones usually take some time to balance out in the baby’s system, and as they do, milia often resolve.

Skin Maturation: The natural maturation of the baby’s skin is another factor behind the development of milia.

As the baby’s skin adjusts to the external environment, it can sometimes trap dead skin cells, leading to the formation of milia. This is a temporary condition, and as the baby’s skin matures, milia tend to resolve on their own.

It’s worth noting that the causes of milia in newborns are typically benign, and milia themselves are generally harmless. They are a common occurrence and don’t pose any health risks to the baby. However, for parents, understanding these causes can provide reassurance and guide them in managing milia. To prevent milia and support healthy skin development, parents can focus on gentle cleansing and moisturizing routines. If milia persist or there are concerns about the baby’s skin, consulting a healthcare professional is always a good idea for proper evaluation and guidance.

Differentiating Milk Spots from Baby Acne

FeatureMilk spots (milia)Baby acne
AppearanceSmall, white, firm bumpsSmall, red, inflamed bumps or pustules
LocationNose, cheeks, chin, forehead, scalp, trunk, genitalsFace, scalp, neck, chest, back
TimingPresent at birth or appear within the first few weeksAppears 2-6 weeks after birth
CauseTrapped keratinHormones passed from mother to baby during pregnancy
DurationWeeks to monthsWeeks to months

In general, milk spots are more likely to appear on the nose, cheeks, chin, and forehead, while baby acne is more likely to appear on the face, scalp, neck, chest, and back. Milk spots are also more likely to be present at birth or appear within the first few weeks, while baby acne is more likely to appear 2-6 weeks after birth.

Safe and Effective Remedies( Treatments) for Milia

Here are some gentle and non-invasive methods to help deal with milia in newborns:

  • Keep the area clean. Wash your baby’s face once a day with warm water and a mild cleanser. Pat the area dry with a clean towel.
  • Use a warm compress. Soak a clean washcloth in warm water and apply it to the affected area for 5-10 minutes. This can help to soften the keratin and make it easier for the milia to go away on their own.
  • Exfoliate gently. Once your baby is a few months old, you can start to exfoliate their skin gently with a soft washcloth or a baby-friendly exfoliating product. This can help to remove dead skin cells and make it easier for the milia to go away.
  • Be patient. Milia usually go away on their own within a few weeks to months. If the milia are still present after a few months, you can talk to your doctor about other treatment options.


  • Do not try to pick or squeeze the milia. This can damage the skin and lead to infection.
  • Do not use harsh soaps or detergents on your baby’s skin. These can irritate the skin and make the milia worse.
  • Do not use any products that contain salicylic acid or benzoyl peroxide on your baby’s skin. These products can be harmful to babies.

If you are concerned about your baby’s milia, please see a doctor. They can help you determine if the milia are a cause for concern and can recommend the best course of treatment.

Professional Treatment Options for Milia

While milia in newborns is generally harmless and often resolves on their own, there are instances where professional treatment may be needed. Healthcare professionals, such as pediatricians or dermatologists, can provide effective treatments when milia persist or are causing discomfort to the baby. Here are some professional treatment options:

1. Incision and Extraction:

  • Procedure: In this method, a healthcare professional uses a sterile needle or lancet to make a tiny incision in the milia and gently extracts the trapped keratin. This should only be performed by a trained medical practitioner to prevent infection and scarring.

2. Cryotherapy:

  • Procedure: Cryotherapy involves using liquid nitrogen to freeze the milia. This freezing process causes the milia to blister, making it easier to remove. The procedure should be performed by a trained medical professional to ensure safety and effectiveness.

3. Topical Retinoids:

  • Procedure: Topical retinoid creams, such as tretinoin, can be prescribed by a dermatologist to promote skin cell turnover and reduce the appearance of milia. This treatment is typically reserved for cases where other methods haven’t been successful.

4. Chemical Peels:

  • Procedure: Chemical peels involve applying a chemical solution to the skin, which causes the outer layer to peel off. This can help in the removal of milia. Chemical peels should be performed by a dermatologist.

5. Laser Therapy:

  • Procedure: Laser therapy, such as CO2 or pulsed dye laser, can be used to target and vaporize milia. Laser treatments should only be administered by experienced medical professionals, as they require precision.

6. Electrodesiccation:

  • Procedure: Electrodesiccation involves using an electrical current to dehydrate and remove the milia. This procedure should be conducted by a trained healthcare provider to avoid scarring or injury.

It’s crucial to emphasize that professional treatments for milia in newborns should only be considered when milia persist and cause concern. Attempting to perform these procedures at home or by untrained individuals can result in complications, including infection and scarring.

Before pursuing professional treatment, parents should consult a healthcare professional, such as a pediatrician or dermatologist, to evaluate the baby’s specific case and receive expert guidance on the most appropriate treatment option. These treatments should always be conducted in a safe and controlled medical setting to ensure the baby’s well-being and the best possible outcome.

milia, commonly referred to as “milk spots,” are a common and usually harmless skin condition that can affect newborns. Understanding the various aspects of milia, including their causes, types, symptoms, diagnosis, and management, is crucial for parents and caregivers to provide the best care for their little ones.

Milia are characterized by small, pearly-white or yellowish cysts that often appear on a baby’s face, especially around the nose, cheeks, and chin. They are typically caused by factors such as blocked sweat glands, hormonal changes, and the natural maturation of the baby’s skin.

Recognizing the symptoms of milia, such as their appearance, location, and painless nature, is essential. Milia are often distinguished from other conditions, like baby acne, by their non-inflammatory nature and distinct appearance.

Diagnosing milia is usually done through a visual examination by healthcare professionals, who look for the characteristic features and may inquire about the baby’s medical history. In most cases, milia do not require extensive diagnostic procedures.

Managing milia at home can involve gentle remedies, such as warm water compresses and gentle exfoliation. Waiting for milia to resolve naturally is often the most effective approach. However, when milia persist, worsen, or raise concerns, consulting a healthcare professional is recommended. Professional treatments, like incision and extraction or cryotherapy, can be considered under medical guidance.
