During pregnancy, the baby is surrounded by amniotic fluid which is isotonic and sterile. At birth, the baby is protected by a protective fatty substance, which covers his skin and protects him from the external environment. This protection wears off a few days after childbirth and the baby's skin becomes drier.
The skin is made up of different layers: the epidermis, dermis and hypodermis. The outermost layer is the epidermis, it is a layer that interfaces between the external environment and the internal environment. Underneath is the dermis, which is the nutrient layer that regulates temperature and fights infection and attacks on the skin. The hypodermis is in the transition zone between the skin and the interior environment, which is a sterile environment.
These layers of cells are all present in children, but they are less developed than in adults. Some cells or glands are still immature in their skin. The baby's skin is very thin and permeable. It is a skin which is poorer in microorganisms and which can therefore defend itself less well against attacks from the external environment. It allows harmful chemicals or microorganisms to pass more easily inside the body.
The skin is an important organ that has different functions :
Because of its poorly developed condition, some of these functions are not functional in children but will become so as they grow. Certain skin problems are then common in the baby, in particular:
The baby's skin will change over time and become more mature. Rest assured, it only takes a few months. During this development we must preserve the skin and body of the baby and help protect him from our external environment.
The skin-to-weight ratio is much higher in babies than in adults. Therefore, when applying a product to a child, the absorbed concentration will be much higher than in an adult. It therefore requires the use of specific products. It is necessary to use products formulated with natural ingredients, of which their number is limited and of which allergenic ingredients are prohibited. The flora present on the child's skin is quite poor. Promoting good hydration helps maintain a balanced and polymorphic flora. It is essential to watch out for acidic products that facilitate the proliferation of harmful germs for the body.
The products made from Castéra Thermal Spring Water are precisely products that will help the child to develop a flora resistant to external aggressions. They regulate the skin flora and are suitable for daily use in newborns and children.
