What is facial dermatitis in children?

What parents worry about most for children is dermatitis. Because children's skin is very delicate, it can easily cause dermatitis and other phenomena. Some children will also have facial dermatitis, which is probably the most troublesome dermatitis symptom for parents, because the child will look ugly. I believe every parent will be very worried, so let's understand why children have facial dermatitis.

(1) Environmental factors

About 30% of children with facial dermatitis deny having a history of genetic allergies. Their serum IGE levels are normal and their peripheral blood lacks specific IGE antibodies. Therefore, exposure to allergens, infection, stress, etc.

Environmental factors also play an important role in the onset of allergies in children with atopic dermatitis.

The most common allergies in children are eczema, asthma and allergic rhinitis, which are known as the childhood allergy triad. All three are related to environmental pollution.

(2) Skin barrier function

Intact skin is the body's natural barrier to resist external physical and chemical damage, invasion of biological antigens, and adapt to the influence of external temperature changes, and plays the role of skin barrier function. This is the epidermal wall theory.

The epidermis, especially the stratum corneum, is the key to the skin barrier function. The lipid and water content of the stratum corneum are crucial to its physiological function. Ceramide is the main component of the intercellular lipids in the stratum corneum, accounting for about 50% of the total lipids, and plays a leading role in the regulation of skin barrier function.

(3) Infection factors

On the one hand, the inherent and acquired immune deficiencies of patients with atopic dermatitis increase their infection rates to bacteria, fungi, and viruses; on the other hand, patients with atopic dermatitis

People with low TH1 lymphocyte activity and cortical dysfunction are prone to various skin infections.

The colonization rate of Staphylococcus aureus in skin lesions is very high, and the amount of colonization is closely related to the severity of the lesions. 90% of atopic dermatitis patients have Staphylococcus aureus on their skin producing superantigen toxins, which is one of the important reasons for the aggravation or development of atopic dermatitis.

After reading the above explanation, you now know why your child has facial dermatitis. In the future, you should pay attention to various things around you, so as to effectively prevent your child's facial dermatitis from continuing to develop. You should also adjust the girl's body in time, so that the girl's facial dermatitis symptoms can gradually improve, which is very helpful for your child.
