Seborrheic dermatitis on the face

Seborrheic dermatitis is a common skin disease. It is easy to occur on the patient's head and face, and it can also occur on the trunk. The occurrence of seborrheic dermatitis has a serious impact on the patient's skin. If seborrheic dermatitis occurs on the trunk, we can slowly treat it, but if it occurs on the face, it will be much more troublesome.

The occurrence of facial seborrheic dermatitis not only affects the patient's skin but also causes great psychological pressure on the patient. Therefore, facial seborrheic dermatitis not only harms the body but also the patient's psychology.

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic papular and scaly inflammatory skin disease that occurs in areas rich in sebaceous glands. This disease is more common in adults and newborns, and is prone to occur in areas rich in sebaceous glands such as the head, face, and trunk.

The cause of this disease is not yet fully understood. The onset of seborrheic dermatitis may be related to sebum secretion, microorganisms, abnormal neurotransmitters, physical and climatic factors, nutritional deficiencies, and the effects of drugs. In recent years, the relationship between Pityrosporum ovale and seborrheic dermatitis has received attention, and it is believed that it plays an important role in the pathogenesis of seborrheic dermatitis. In addition, mental factors, eating habits, vitamin B deficiency and alcoholism may also have a certain impact on the occurrence and development of this disease. Widespread and persistent seborrheic dermatitis can be an important cutaneous symptom of HIV infection.

1. General treatment

Live a regular life, get enough sleep, adjust your diet, eat more vegetables, limit high-fat and high-sugar foods, avoid drinking alcohol and spicy foods, and avoid excessive mental stress.

2. Topical medication

(1) Glucocorticoids are mainly used for skin lesions with severe inflammation. Medium- or high-potency glucocorticoid preparations can be applied externally, which have good therapeutic effects, but should not be used for a long time, especially on the face. Low-potency glucocorticoid preparations (such as hydrocortisone) are less effective and are suitable for infants and young children.

(2) Antibacterial drugs: 2% erythromycin ointment or gel, 5% metronidazole cream, or a cream containing 1% chloramphenicol and 0.1% dexamethasone.

(3) Selenium sulfide lotion has the effect of killing fungi and inhibiting bacterial growth. It can also reduce sebum secretion and the content of fatty acids in sebum.

(4) Zinc pyrithione shampoo: The concentration of zinc pyrithione shampoo is 1% to 2%. In addition to being used on the scalp, it can also be used on other parts of the body, such as the face, brow arches, and trunk. Do not apply to eyelid margins to avoid eye irritation. Apply the medicine to the affected area, leave it on for 1 to 2 minutes, and then wash it off with clean water. Apply 1 to 2 times a day. When symptoms are under control, change to once a day, but you must persist in applying it to avoid recurrence. The shampoo has an inhibitory effect on the proliferation of epidermal cells. In addition, it has a broad-spectrum antibacterial effect and can inhibit the growth of Pityrosporum ovale.

(5) Antifungal preparations Antifungal preparations, especially imidazole drugs, have good therapeutic effects. Shampoos or creams containing ketoconazole (2%), itraconazole, econazole, clotrimazole, miconazole, oxiconazole, isoconazole, or ciclopirox and terbinafine (1%) preparations are commonly used. In addition to antifungal effects, antifungal preparations also have multiple effects such as anti-inflammatory, antibacterial and inhibition of cell wall lipid formation.

(6) Sulfur and/or salicylic acid lotions and other sulfur and/or salicylic acid have antibacterial and anti-dandruff effects and have a certain therapeutic effect on this disease, but they are not as good as zinc pyrithione and selenium sulfide, and are highly irritating. Coal tar preparations have anti-inflammatory, antibacterial and antimitotic effects, but are colored, smelly and irritating, so they are usually only used on the scalp.

3. Internal medication

(1) Glucocorticoids such as prednisone are used to treat cases with large skin lesions and severe inflammation. The course of treatment is usually limited to 7 to 10 days and should not be too long.

(2) Tripterygium wilfordii glycosides are suitable for patients with obvious and large-scale inflammation. The effect will be better if combined with low-dose glucocorticoids.

(3) Antibiotics: Severe seborrheic dermatitis lesions are often accompanied by bacterial infection (mainly Staphylococcus aureus infection), sometimes even with pustules and enlarged cervical lymph nodes. Appropriate use of antibiotics is beneficial, such as tetracycline or erythromycin.

(4) B vitamins include vitamin B2, vitamin B6 and vitamin B complex. Long-term oral administration may have certain benefits for this disease.
