Your little one's skin is a lot thinner than that of an adult, and the top skin layer has a looser structure and is less resistant. The barrier effect against pollutants is not as well developed and the skin reacts more sensitively to its environment.
The natural acid protection layer of the skin forms over the first few weeks and regenerates in older children more slowly than in an adult. It has the important function of keeping out bacteria and pathogens.
The top skin layer of children contains more moisture than adults’. At the same time, less sebum is produced. This means that children’s skin is covered by a very thin, water-oil layer and can easily dry out. The protection against cold and injury is also lower.
