(HealthDay News) -- Acne doesn't just appear on teenagers and adults.
It is also common on a baby's cheeks during the first few months of life, and is known as neonatal acne.
According to the Children's Hospital of Philadelphia, neonatal acne is caused by hormonal stimulation of glands in the cheeks, and appears between the ages of 2 and 4 weeks. It consists of red bumps or pimples.
Parents should keep the baby's cheeks clean and dry, and know that baby lotions or oils can make the condition worse. However, the acne is temporary and should disappear by the ages of 4 months to 6 months.
If the rash spreads, gets worse, or the baby experiences a fever, parents should see a pediatrician.
