Eczema and psoriasis tend to show up at different stages of life. They both occur equally in men and women. (You can have both conditions, but it’s not common.) Eczema is most common in babies and young children, and they sometimes outgrow it. However, teenagers and adults can also develop eczema. It is rare for someone over 60 to develop eczema. Unlike eczema, psoriasis is rare in babies. Symptoms of psoriasis usually begin between the ages of 15 and 35. It is a lifelong condition.
