Newborn Skin: Baby Acne, Peeling, Milia & What's Normal

Real newborn skin is not the airbrushed, peachy-smooth skin of baby product advertising. It's blotchy, peeling, potentially spotty, and covered in a mysterious white coating. All of this is completely normal — and most of it requires nothing from you except patience.

Vernix

The white, waxy coating covering your newborn at birth is called vernix caseosa. It forms in the womb to protect baby's skin from amniotic fluid. You don't need to wash it off — midwives increasingly recommend rubbing it in rather than removing it, as it has moisturising and antibacterial properties.

Peeling skin

In the first week or two, almost all babies' skin will peel — particularly on the hands, feet, and ankles. This is the transition from a watery womb environment to dry air. It looks dramatic but requires no treatment. Don't peel it off — let it shed naturally.

You can use a small amount of unfragranced baby oil or moisturiser if it looks very dry and uncomfortable, but it's rarely necessary.

Milia

Tiny white or yellow-white spots, typically across the nose and cheeks. Milia are caused by blocked sebaceous glands and are incredibly common — affecting around 50% of newborns. They look like whiteheads but are not acne and will not pop.

Treatment: None needed. They disappear on their own within 4–6 weeks. Don't squeeze or attempt to pick them.

Baby acne (neonatal acne)

Around 2–4 weeks, many babies develop a spotty rash that looks remarkably like teenage acne — red spots, sometimes with whiteheads, predominantly on the cheeks, forehead, and chin.

Cause: Thought to be caused by maternal hormones transferred through the placenta or breast milk, stimulating the baby's oil glands.

Treatment: None required. Wash the face gently with plain water. Don't use acne products, steroid creams, or anything marketed for adult acne. It resolves on its own within a few weeks to months.

Erythema toxicum

Despite its alarming name, erythema toxicum is a completely harmless rash affecting up to half of all newborns. It appears as red blotches with a central yellow or white spot, scattered across the body (but not the palms or soles). It typically appears 1–3 days after birth and fades within 1–2 weeks.

No treatment needed. It looks worse than it is.

Mongolian spots (congenital dermal melanocytosis)

Flat, blue-grey patches that look like bruises, most commonly on the lower back and buttocks. They're caused by melanin-producing cells in the deep layer of the skin. Common in babies of Asian, African, and some Mediterranean heritage.

They are completely harmless and fade gradually — most disappear by school age. If you have them, let your health visitor note them in the records (occasionally mistaken for bruising).

Stork marks / salmon patches

Flat, pink or reddish patches, most commonly on the back of the neck ("stork mark"), between the eyes, or on the eyelids ("angel kisses"). Caused by superficial blood vessel clusters under the skin.

Stork marks on the neck often persist into adulthood but are covered by hair. Facial ones usually fade significantly within 1–2 years.

Strawberry naevus (infantile haemangioma)

A raised, bright red birthmark that appears in the first few weeks and grows rapidly in the first year before slowly fading. They can be alarming as they grow — but in the vast majority of cases they shrink on their own and leave minimal trace by age 7–10.

See your GP if:

• Haemangioma is on the face near the eye (can affect vision)
• Bleeds repeatedly or shows signs of ulceration
• Located near the mouth or airway
• You're concerned about the rate of growth

Cradle cap (seborrhoeic dermatitis)

Yellow, greasy, scaly patches on the scalp (and sometimes face and behind the ears). Very common from 2 weeks to several months. Not itchy, not contagious, not caused by poor hygiene.

Treatment: Gentle massage with baby oil or coconut oil left for 30 minutes, then gentle brushing with a soft baby brush followed by washing. Repeat as needed. Resolves on its own.

What actually needs a GP appointment

See your GP if:

• Rash is spreading rapidly and baby has a fever
• Rash includes tiny dark purple spots that don't fade when pressed with a glass (could be meningitis — call 999)
• Skin looks yellow (possible jaundice — see your midwife same day)
• There are blisters or open sores
• Baby seems unwell alongside any skin changes

Most newborn skin oddities are benign and self-resolving. When in doubt, a photo sent via your GP's online consultation system can often get quick reassurance without an in-person appointment.
