Many newborn babies have skin conditions. Some get rashes in their first few months of life. Some are born with birthmarks. Most bumps and spots on a baby’s skin are harmless. Most will clear up on their own.
It’s important to know which rashes and birthmarks are common. This will help you identify an uncommon condition that should be seen by a doctor.
Path to improved health
Many babies develop rashes soon after birth. Most of these are common and do not cause any harm. Many can be treated at home.
Common newborn rashes

Common newborn birthmarks
Birthmarks are common in babies. They are usually harmless and often fade or disappear completely over time.
Salmon patches (also called “stork bites” or “angel kisses”)
These are mainly found on the back of the neck or between the eyebrows. They are just a collection of blood vessels. Many fade over a few months. Sometimes, especially on the back of the neck, they may never go away completely.
These smooth, flat, blue-gray marks tend to appear on the lower back or buttocks. They are collections of pigment that didn’t make it to the top layer of the skin. They usually fade by school age, but may never disappear completely. They are common in dark-skinned babies.
These flat, brown marks appear in oval shapes. They could get bigger or darker. Your baby may get more as they grow up.
These marks are formed by blood vessels that didn’t develop properly. They are pink or red at birth but grow into a darker red-purple color. They can be large. Lighter ones may fade. Others could grow bigger, thicker, and darker.
These raised birthmarks are formed by a clump of blood vessels. They vary in size and shape. They often appear blue, red, or purple. Most grow for about a year, then gradually shrink and fade.
What about jaundice?
Jaundice is not a rash, but it is noticeable through the skin. Newborns with jaundice have a yellow tint to their skin and the whites of their eyes. It usually goes away a few days after birth. It can cause health problems if it gets bad enough. If your newborn looks yellow to you, call your family doctor right away. Treatment for jaundice involves laying the baby under a special light for a number of hours or days. Babies with severe jaundice may need to receive treatment in a hospital.
Things to consider
Most newborn rashes are harmless and go away by themselves. But sometimes a rash is a symptom of an infection. These can be dangerous to a newborn baby. Call your doctor if you notice any of the following signs or symptoms in your infant.
- Any rash along with other symptoms, such as fever, lethargy, cough, excessive fussiness, or poor feeding.
- Increased pain, swelling, or warmth in an area of the rash.
- Red streaks extending from an area of the rash.
- Swollen lymph nodes in the neck, armpit, or groin.
- Fluid-filled blisters (especially yellow, opaque fluid).
- Pinpoint red or purplish dots (called “petechiae”) all over the body that do not lighten with pressure.
