Babies are unique, not the small models of adults. Compared to the adults, the baby skin has structural, functional and functional differences. The baby skin contains less moisturizing factor than adult skin, meaning there is less melanin. It absorbs water very quickly, but it also loses water, i.e. moisture quickly. Adult and baby skin surfaces are also different, baby skin is thinner. Therefore, the baby skin barrier is more delicate and thin; it can easily lose the barrier property, and its allergens can easily permeate the skin. All these reasons require the baby skin to be protected with care.
