Eczema is a chronic disease of the skin that is becoming more common worldwide for reasons unknown. Currently the best indicator that a baby will suffer from eczema is if either or both parents have the condition, although this is not always the case. The goal of this study is to find out if, from birth, the skin of babies who later go on to suffer from eczema develops differently to those who do not. By doing this the research team hope to detect early signs of the disease within the first year of life. Our researchers will ask 150 families from the local Sheffield community to take part in a 1-year study.
