Eczema is a common skin condition that affects children, and there are two types that are most commonly seen - atopic eczema and irritant eczema. Atopic eczema is more common in urban areas, likely because of the lack of exposure to microbes in the environment. The skin with atopic eczema is also less able to retain moisture, making it more reactive to the environment and susceptible to the itch-scratch cycle. It's crucial to keep the affected skin moisturized with products that don't contain fragrances, fillers, colors, or preservatives, as they can trigger the itch-scratch cycle.
