A prevalent and benign skin condition, alternatively known as erythema neonatorum or toxic erythema, which impacts newborn babies. The exact cause remains uncertain. Neonatal urticaria manifests as a mottled rash, with elevated white or yellow bumps encircled by poorly defined reddened regions of inflammation. This rash predominantly appears on the face, chest, arms, and thighs. Generally, it tends to resolve on its own without requiring treatment.
