How does eczema on baby face cause

Infants with eczema are mainly caused by genetic factors, allergic factors, environmental factors, improper skin care, infection factors, other factors, etc. 1. Genetic factors If there is a history of eczema, asthma, allergic rhinitis, etc. in the family, the probability of eczema in infants will be relatively high. Because the genetic background may lead to a relatively weak skin barrier function, more sensitive to external stimuli, easy to induce eczema.2. Allergic factors Infants may be allergic to certain ingredients in food, such as milk, eggs, fish and shrimp and other high-protein foods, or contact with certain allergens, such as dust mites, pollen, animal hair, etc., may cause eczema. When the baby ingests or contacts these allergens, the immune system will produce abnormal reactions, leading to inflammation and eczema of the skin. 3. Environmental factors The baby's environmental temperature and humidity are not suitable can also induce eczema. Temperature is too high or too low, the environment is too dry or humid, may cause adverse effects on the baby's skin, destroy the normal barrier function of the skin, and then cause eczema. In addition, chemicals, pollutants, etc. in the environment may also irritate the skin and induce eczema. 4. Improper skin care If the baby's skin is excessively cleaned, or if the baby's washing products are used, the barrier function of the skin may be damaged, leading to eczema. At the same time, if you do not pay attention to keeping the baby's face clean and dry, sweat, saliva and other long-term irritation of the skin, it is also easy to cause eczema. 5. Infection factors Local infection of the baby's skin, such as bacteria, viruses, fungi and other infections, may also induce eczema. Infection can lead to increased skin inflammation, and then cause eczema or make the original eczema worse. 6. Other factors The baby's emotional state, sleep, etc. may also be related to the occurrence of eczema. Excessive crying, lack of sleep, etc. may affect the baby's immune system and skin condition, increasing the risk of eczema.
