From the age of 4, the hydrolipidic film of children's skin is in full construction. The skin is therefore more vulnerable to external aggressions and it is 3 times thinner than that of an adult. The dermis is immature with small spaced cells which intensify water loss and ultimately the dehydration of the child's skin.
In addition, the which participate in the creation of the hydrolipidic film and which help to fight skin dryness are not very active.
In summary, c.ildren's skin is particularly sensitive and fragile and requires a daily routine including hydration and protection.
