Seborrheic dermatitis on the face

Seborrheic dermatitis can sometimes occur on the face. Because the face is a dense area where sebum is distributed, if the patient's sebaceous glands are active due to specific factors, such as staying up late, excessive fatigue, and other bad living habits, the sebaceous glands on the face will inevitably secrete a large amount of sebum. If sebum is distributed on the surface of the skin, it may stimulate local opportunistic pathogens to produce inflammation, such as local Pityrosporum ovoid infection, which may cause seborrheic dermatitis. Patients who exhibit this inflammation may be accompanied by distinct flushing patches, and oily scales or dry scales may be produced on top of these flushing patches.
