1. What causes seborrheic dermatitis?

The exact cause and pathogenesis of seborrheic dermatitis have not yet been fully elucidated. However, a large number of studies have shown that the pathogenesis of seborrheic dermatitis may be related to genetic, immune, neural, hormonal and environmental factors. It is also related to digestive dysfunction, excessive sugar and fat intake, mental stress, overwork, bacterial infection, and vitamin B deficiency. Abnormal sebum composition and excessive sebum secretion are the basis for the onset of seborrheic dermatitis. On this basis, the number of Malassezia may increase, or a large amount of free fatty acids may be secreted on the surface to irritate the skin and cause inflammatory lesions in that area of ​​the skin.

2. What are the symptoms of seborrheic dermatitis?

Seborrheic dermatitis manifests itself as inflammatory changes in seborrheic (oil-producing) areas such as the scalp, face, upper chest, and armpits. It can be divided into dry seborrheic dermatitis and oily seborrheic dermatitis. People with dry seborrheic dermatitis have drier skin, which manifests as dandruff and itching on the scalp. Oily seborrheic dermatitis occurs in people with excessive oil secretion, and is commonly manifested by greasy yellow-red patches and papules. In severe cases, there may be erosion, exudation, and greasy crusts, and it is often extremely itchy. The disease progresses slowly with repeated attacks. If secondary bacterial infection occurs, pustules or even ulcers may appear. In some cases, the rash may develop into erythroderma.
