<s>[INST] How does eczema affect people of different ages? [/INST] Eczema is a chronic health problem that affects people of all ages, but is most common in babies (infants):

Infantile eczema occurs in around 20% of children under two years of age, and usually starts in the first six months of life. Infantile eczema usually improves significantly between the ages of two to five years.
Childhood eczema may follow infantile eczema, or start from two to four years of age. Rashes and dryness are usually found in the creases of the elbows, behind the knees, across the ankles and may also involve the face, ears and neck. This form of eczema usually improves with age.
Adult eczema is similar to that of older children with areas of very dry, itchy, reddened skin at the elbow creases, wrists, neck, ankles and behind the knees. It can cause rough, hard and thickened skin, which may also have weeping areas. Although eczema tends to improve in midlife, and is unusual in elderly people, it can occur at any age. Source: ASCIA.
