Let's talk about my views.

How does seborrheic eczema cause?

Reason 1: the cause of the disease is not very clear. This disease is a kind of inflammation on the basis of sebum overflow, which may be related to the increase of sebum secretion and the change of its chemical composition. It is also suggested that in patients with seborrheic eczema, the surface lipid secretion does not increase, but the cholesterol, triglyceride and paraffin increase, while squalene decrease.

Reason 2: in recent years, some scholars believe that Malassezia symbiosis with normal people may be related to the onset and aggravation of seborrheic eczema. Malassezia antigen can sensitize patients with seborrheic eczema and induce the body to produce specific IgG, IgM and IgA antibodies,

The third reason is that the excessive growth of Malassezia and its metabolites into the epidermis lead to immune inflammation. Patients prone to seborrheic eczema can be induced by fatigue, emotional stress or infection. AIDS patients often show severe disseminated seborrheic eczema, which may be related to Malassezia overgrowth caused by immune deficiency.
