The most common type of eczema is atopic dermatitis. It is most common in babies and children but adults can have it too. As children who have atopic dermatitis grow older, this problem may get better or go away. But sometimes the skin may stay dry and get irritated easily.
3. Eczema. Like baby acne, eczema is very common in newborns, but itâs usually caused by dry (not oily) skin. Mild eczema can cause lots of small bumps, similar to baby acne. Since it often starts on the cheeks, itâs easy to confuse with baby acne. But, if it spreads into a rash that covers the skin or develops in other areas of your babyâs body, such as the folds of his elbows and knees, then itâs probably eczema, not acne.
