How to Tell the Difference Between Baby Acne, Milk Spots, and Cow’s Milk Allergy Rash

When raised bumps or spots appear on your new baby’s previously perfect skin, it can cause concern – especially so as cow’s milk protein allergy (and others) become more common. But does your infant have baby acne, baby milk spots, or milk rash – and what’s the difference between them? This post will be looking at milk spots vs CMPA rash, milk allergy vs baby acne, milia vs milk allergy, and everything in between, plus reflux vs milk allergy babies.

When your tiny infant presents with any kind of blemish, it can be worrying. This guide should help you to identify whether your baby is presenting with milk spots, an allergy rash, or baby acne.

What’s the Difference Between Baby Acne, Milk Spots, and Milk Rash?

One is thought to be hormonal, one a response to the environment outside of the womb, and one an allergy reaction. But which is which, and how serious are they? This post will help you identify and distinguish between these three infant skin complaints.

Milk Spots Baby Rash, Also Known as Milia

What Are Newborn Milk Spots?

What are milk spots on babies? Firstly, if you’re researching milk spots vs milia, they are the same thing. Milia are tiny white bumps that appear on the face, typically on the nose, chin, and cheeks, although they can also develop on the chest, arms, and legs. Sometimes they can appear in and around the baby’s mouth and oral milia are known as Epstein pearls.

Milia often mistakenly referred to as baby acne or milk rash, which are not the same, however it’s worth noting that they may occur together.

Milia Symptoms: What Do Milia Look Like?

What do milk spots look like? Milia have a distinctive appearance and are often called baby milk spots because of their appearance – they resemble a spray of milk on the face – however, they’re not linked to either breastfeeding or formula.

The following image is a classic representation of milk spot rash. Milk spots across the bridge of the nose are very common, as you can see in the following example.

Milk spots, newborn:

The white bumps are deep under the skin and do not have the typical redness or swelling associated with whiteheads.

What Causes Milia Baby Spots?

Milia in babies are caused by flakes of dead skin becoming trapped in pockets under the skin, and this is what causes milk spots.

They are unrelated to how the baby is fed, or the mother’s diet if breastfeeding.

How Serious is Milia?

Are milk spots bad for your baby? You’ll be relieved to know that Milia and Epstein pearls (milia located on the roof of the mouth and gums) are common and completely harmless. They usually disappear within three months of birth.

Milia baby spots can affect older children and adults, though there’s usually a cause, such as injury or inflammation.

How to Get Rid of Milk Spots

If you’re concerned and worrying how to get rid of milk spots on baby, rest assured there’s no need to do anything more than keep your infant clean – certainly picking milk spots is not advised as this can both cause your baby pain and introduce bacteria.

Milia should disappear naturally within a few weeks or months of birth.

Do I Need to See a Doctor About Milia?

There’s no need to see a GP unless you have specific concerns or the bumps worsen or remain after the few months of life.

Milk Spots vs Baby Acne vs Rash

When it comes to milia vs baby acne or a rash, it can be difficult to know whether the condition your infant is displaying with is harmless, or something to be more concerned about. If you’re not convinced the skin complaint your baby is displaying with is milia, read on to see whether baby acne is more likely…

Baby Acne

What Is Baby Acne?

Affecting around 20% of babies, baby acne (also known as neonatal acne) is common. Occasionally baby acne can be present at birth, however it more commonly develops in the first few weeks of life.

Baby Acne Symptoms: What Does Baby Acne Look Like?

Baby acne presents as small spots or whiteheads, usually on your baby’s cheeks, though it can appear anywhere on the face. Unlike infantile acne, baby acne does not usually appear as blackheads. Here’s an example:

The affected area may be a little red and irritated, and fussing or crying may make the acne more pronounced. Baby acne can sometimes also develop on the upper back and neck.

What Causes Baby Acne?

Health professionals believe baby acne may be caused by the maternal hormones surging through the mother’s body around the time of birth.

How Serious is Baby Acne?

Unlike infantile acne which is less common and more complicated, baby acne is harmless and usually resolves itself within a few weeks or months. Infantile acne can remain until toddlerhood and in untreated cases may rarely result in scarring.

Do I Need to See a Doctor About Baby Acne?

You don’t need to see a GP unless you have specific concerns or the spots worsen or remain after the few months of life.

Baby Acne vs Milk Allergy

If you’re looking at symptoms of baby acne vs CMPA rash and you’re still concerned that your child’s rash stems from a more serious issue, read on to find out how to identify baby acne or allergy in your infant.

Dairy Allergy Milk Rash vs Milk Spots

Some people incorrectly use these terms interchangeably; milk spots (milia) are harmless, while an allergic milk rash should not be ignored. Read more about breastfeeding with CMPA.

What Is a Baby Milk Allergy Rash?

Baby milk allergy rash occurs as a result of exposure to an allergen. One of the most common allergies in infants is CMPA, or cow’s milk protein allergy. CMPA affects around 2-3% of babies, but it’s much rarer for baby’s to react through breastmilk than direct exposure via formula (around 0.5%).

What Does Cow’s Milk Allergy Rash Look Like?

CMPA rash vs baby acne is quite apparent when you know what to look for. An infant milk rash caused by a dairy allergy, looks like severe acne. The rash is often angry and extensive, creeping beyond the hairline and onto the ears. Eliminating the allergen from the infant’s diet will allow the rash to heal and disappear.

Milk rash, caused by a dairy allergy:

What Causes a Milk Rash?

CMPA is caused by an abnormal response to cow’s milk protein by the immune system.

How Serious is Cow’s Milk Allergy Rash?

The seriousness of the rash relates to the allergy, as opposed to the superficial aspect of the rash itself. Allergies vary in severity, but should not be ignored. More information on identifying and managing CMPA.

Do I Need to See a Doctor About CMPA?

It’s recommended to seek help from a dietitian who specialises in allergies once diagnosis is confirmed. Referral is via your GP.

Reflux vs Milk Allergy Babies

Another symptom you may see if your baby has an allergy is reflux, as well as other gastro symptoms. Take a look at my post all about CMPA symptoms for the full list.

What is Reflux?

Reflux is when your infant brings up their milk. You may also notice gagging, coughing, difficulty feeding, nasal congestion, and breathing problems, such as wheezing.

If the symptoms are similar but without spitting up, your baby may be experiencing silent reflux, where they swallow any regurgitated milk.

Both of these conditions can be caused by an allergy, and may result in poor weight gain.

Caring For Milk Allergy Babies

If you suspect your baby is suffering from a food allergy, you may like to keep a food diary to help confirm, particularly if you suspect multiple allergens or if your baby is being cared for outside of the home.

Cow’s Milk Allergy Rash – Breastfed Babies

I’ve created an allergy food diary specifically for breastfeeding mothers of allergy babies, to help you record, track, and analyse data. This is especially helpful for when you begin dairy free weaning, or if your baby is cared for outside of the home. You can get your physical or downloadable copy here:

Looking After Baby’s Skin: Treatment for Baby Acne, Milia, or Milk Rash Caused By an Allergy

Although blemishes on your infant’s face may be unsightly and undesirable, in most cases they are completely harmless and require no treatment. This is not true of allergies which require attention and support from health professionals.

To best care for your baby’s delicate skin:

• Keep the face clean – gently wipe away milk, spit up, and vomit promptly;
• Be gentle – avoid using harsh chemicals or scented products which may irritate the skin, and pat, don’t rub dry;
• Leave spots alone – don’t squeeze or scrub as this may aggravate the condition.

If symptoms worsen or appear to distress your baby, or if you have any other concerns, always see your GP.
