Baby's skin

The skin of a newborn baby is five times as thin as an adult skin, making it much more delicate and sensitive. The baby skin does not yet have a protective acid mantle. The acid mantle is a "jacket" that protects against dehydration, irritation and infections. The horn layer, part of the epidermis, is not yet fully grown. It protects against bacteria and is not fully developed until the fourth year of age. Therefore, the baby's skin dries out faster and is more sensitive to UV radiation, because babies have less skin pigmentation than adults.
