Skin diseases that cause rashes in newborns

Often newborns have rashes or other skin problems.

  • Cheeks
  • Nose,
  • Head.

The acne baby or neonatal acne can be seen during the first weeks of life and often goes by itself in a few months.

After birth, the maternal hormones remain in the baby’s body. 
Neonatal acne:

  • It is the reaction caused by these hormones,
  • It passes by itself in a short time.

Small white spots appear very often on the face of a newborn during the first week and are called milia. 
The baby’s skin looks stained. 
These points disappear by themselves in a few weeks.

During the first day or two of life, many children have harmless red patches with small pimples that sometimes contain pus.
