Baby skin is sensitive and changes frequently. If you are noticing white patches on baby's skin, here is what you need to know.

The short answer

White or lighter patches on a baby's skin are usually caused by common, harmless conditions. Pityriasis alba is the most frequent cause in children - it creates slightly scaly, pale patches, especially on the cheeks and arms, and is related to dry skin and mild eczema. Vitiligo (true loss of pigment) is rarer in babies but possible. Tinea versicolor is a harmless fungal condition that creates lighter patches. Most white patches in children are not concerning, but a dermatology evaluation can provide a clear diagnosis.

What Parents Should Know

According to AAP, NIH guidelines, white or lighter patches on a baby's skin are usually caused by common, harmless conditions. Pityriasis alba is the most frequent cause in children - it creates slightly scaly, pale patches, especially on the cheeks and arms, and is related to dry skin and mild eczema. Vitiligo (true loss of pigment) is rarer in babies but possible. Tinea versicolor is a harmless fungal condition that creates lighter patches. Most white patches in children are not concerning, but a dermatology evaluation can provide a clear diagnosis. At 0-12 months, white patches in babies are uncommon. If present, they could be birthmark-related (nevus depigmentosus - a flat, white birthmark that stays the same size relative to growth), or early signs of a condition. Ash-leaf spots (small, oval white patches) can be present from birth and are usually harmless, but multiple ash-leaf spots may warrant evaluation as they can be associated with tuberous sclerosis. It is generally considered normal when slightly pale, dry patches on the cheeks that become more noticeable in summer (likely pityriasis alba). However, you should contact your pediatrician promptly if multiple ash-leaf-shaped white spots are present in a young baby (evaluation for tuberous sclerosis may be recommended).

By Age

What to expect by age

0-12 months

White patches in babies are uncommon. If present, they could be birthmark-related (nevus depigmentosus - a flat, white birthmark that stays the same size relative to growth), or early signs of a condition. Ash-leaf spots (small, oval white patches) can be present from birth and are usually harmless, but multiple ash-leaf spots may warrant evaluation as they can be associated with tuberous sclerosis.

1-3 years

Pityriasis alba is the most common cause of white patches in toddlers. These slightly scaly, poorly defined pale patches appear on the face (especially cheeks), upper arms, and trunk. They are more noticeable in darker-skinned children and in summer when surrounding skin tans. It is a mild eczema variant that resolves on its own over months to years. Regular moisturizing and sun protection help. Tinea versicolor can also cause lighter patches but is more common in adolescents.

What to Tell Your Pediatrician

  • Describe when you first noticed white patches on baby's skin and how it has changed over time.
  • Note your baby's current age and which age-specific patterns you are seeing.
  • Mention if white patches are new and spreading.
  • Mention if the patches are completely white (stark white vs. slightly lighter than surrounding skin).
  • Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
  • Bring a list of any questions or observations you want to discuss at the appointment.

What Should You Do?

When to take action

Probably normal when...
  • Slightly pale, dry patches on the cheeks that become more noticeable in summer (likely pityriasis alba)
  • A single small white birthmark-like patch that has been present since birth and is not changing
  • White patches that improve with moisturizing and gentle skin care
Mention at your next visit when...
  • White patches are new and spreading
  • The patches are completely white (stark white vs. slightly lighter than surrounding skin)
  • You want a definitive diagnosis to know the cause
  • White patches are accompanied by changes in hair color in the affected area
Act now when...
  • Multiple ash-leaf-shaped white spots are present in a young baby (evaluation for tuberous sclerosis may be recommended)
  • White patches are spreading rapidly and affecting large areas of the body
  • White patches are accompanied by other symptoms like seizures, developmental changes, or a growing birthmark

What You Can Do at Home

  • Keep track of when you notice white patches on baby's skin — noting the time of day, duration, and any triggers can help your pediatrician.
  • Remember that slightly pale, dry patches on the cheeks that become more noticeable in summer (likely pityriasis alba) — this is generally within the range of normal.
  • At 0-12 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
  • Use fragrance-free, hypoallergenic products on your baby's skin. Avoid over-bathing — 2-3 baths per week is usually sufficient.
  • While monitoring at home, seek immediate care if multiple ash-leaf-shaped white spots are present in a young baby (evaluation for tuberous sclerosis may be recommended).

Baby Eczema (Atopic Dermatitis)

Baby eczema is extremely common, affecting up to 20% of infants, and is not caused by anything you did wrong. It shows up as dry, red, itchy patches and is very manageable with consistent moisturizing and gentle skin care. Most children outgrow it by school age.

Baby Dry Skin & Peeling Skin

Dry and peeling skin in newborns is completely normal, especially in the first few weeks after birth. Your baby spent nine months floating in amniotic fluid, so some peeling as they adjust to the outside world is expected. Gentle, fragrance-free moisturizers applied after baths are usually all that is needed.

Baby Dry Patches on Cheeks

Dry patches on your baby's cheeks are very common, especially during cold or dry weather. Baby skin is much thinner and more sensitive than adult skin and loses moisture easily. In most cases, regular application of a gentle, fragrance-free moisturizer is all that is needed. If patches are red, rough, or itchy, mild eczema may be the cause.

Baby Birthmarks

Birthmarks are extremely common -- more than 80% of babies have at least one. Most birthmarks are completely harmless and many fade or disappear on their own over time. The type, location, and any changes over time help your pediatrician determine whether any follow-up is needed.

My Baby Has an Extra Nipple (Accessory Nipple)

Accessory (supernumerary) nipples are one of the most common minor congenital findings, occurring in about 1 in 18 people. They appear as small, flat, often pigmented bumps along the "milk line" — an embryonic line running from the armpit to the groin on each side. Most people mistake them for moles. Accessory nipples are almost always harmless and require no treatment. In rare cases, they may be associated with kidney abnormalities, so some pediatricians recommend a renal ultrasound if one is found, though this practice varies.

My Baby Was Born with a Raw Spot on Their Scalp (Aplasia Cutis)

Aplasia cutis congenita (ACC) is a condition where a baby is born with a small area of missing skin, most commonly on the scalp. It occurs in about 1 in 10,000 births. The affected area may look like a raw wound, an ulcer, or may have already healed into a thin, shiny scar by the time of birth. Most cases are small, isolated, and heal well with basic wound care — the area eventually forms a hairless scar. Larger defects or those associated with other findings may need more investigation, but isolated small ACC has an excellent prognosis.
