Seborrheic dermatitis is a chronic, superficial inflammatory skin disease with papular and scaly lesions that occurs in areas with excessive sebum secretion, often accompanied by varying degrees of itching. When seborrheic dermatitis affects the face, our clinical treatment mainly includes three aspects. The first is topical medication treatment, which can involve the use of low-concentration tacrolimus ointment or pimecrolimus cream, as well as zinc oxide oil, nitrofurazone ointment, zinc oxide and boric acid ointment, etc. If necessary, short-term use of compound preparations containing glucocorticoids and antibiotics, such as compound miconazole ointment and compound econazole ointment, may be employed. The second is oral medication, which can supplement B-group vitamins, primarily B2, B6, or a compound vitamin B, as well as zinc-containing preparations. For severe itching, antihistamines can be taken orally. In cases of bacterial infection, antibiotics such as erythromycin or tetracycline can be used, and can be supplemented with traditional Chinese herbal decoctions. The third aspect is to inform patients to maintain a regular lifestyle with sufficient sleep, limit high-carbohydrate and high-fat diets, avoid spicy and irritant foods, avoid alcohol consumption, eat more vegetables and fruits, avoid various mechanical irritations, and use less hot water and highly alkaline soap when washing the face.
