Seborrheic dermatitis is a common chronic recurrent inflammatory skin disease, which frequently occurs in areas with excessive sebum secretion such as the face, chest, and back. The exact cause of the disease is not yet clear, but it is related to factors such as Malassezia infection, increased lipids, impaired skin barrier function, immune responses, and individual susceptibility. In daily life, factors such as mental stress, lack of B vitamins, consumption of spicy foods and alcohol, and chronic sleep deprivation can affect the condition to varying degrees. In terms of treatment, it is important to first adjust lifestyle habits, including managing sleep schedules to sleep by 11 PM and regulating emotions. For local care, avoid excessive washing of the skin and focus on enhancing skin moisturization. Dietary adjustments should include lighter meals and abstaining from alcohol. For topical use, metronidazole gel and some antimicrobial ointments can be applied. Traditional Chinese medicinal solutions can also be used to clear heat, detoxify, reduce redness, degrease, kill parasites, and provide antibacterial and anti-itch effects. (Note: The use of medications should be under the guidance of a physician.)

Will seborrheic dermatitis recur?

Seborrheic dermatitis is likely to recur. In cases of seborrheic dermatitis, oily skin can easily lead to recurrence. Additionally, an inappropriate diet, often consisting of spicy, irritating food, as well as fried and greasy food, and habitual late nights, can also easily lead to recurrence. Therefore, when seborrheic dermatitis occurs, it’s essential to maintain a light diet, avoiding spicy and irritating foods, and seek treatment under the guidance of a doctor. For topical use, one can choose corticosteroid medications, typically choices include desonide ointment or hydrocortisone butyrate cream. For oral medications, options include Vitamin B6 or a B-complex vitamin. If itching is significant, it might also be necessary to combine treatment with antihistamine medications.

How is seborrheic dermatitis formed?

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic papular and scaly superficial inflammatory skin disease that occurs in areas where sebum is excessively secreted. It commonly affects areas rich in sebaceous glands such as the head, face, and trunk, and is more frequently seen in adults and newborns, often accompanied by itching of varying degrees. The exact cause of this disease is not completely understood; however, it is generally believed to be related to an increase in sebum secretion or changes in its chemical composition. Additionally, colonization and infection by Malassezia yeast play a certain role. Other factors such as mental stress, diet, deficiency in B vitamins, and alcohol abuse also influence the occurrence and progression of the disease to varying extents.

Is seborrheic dermatitis eczema?

Seborrheic dermatitis, also known as seborrheic eczema, is not actually eczema. It is a chronic, papular, scaly superficial inflammatory skin disease that commonly occurs in areas rich in sebaceous glands, such as the head, face, and trunk, and can be accompanied by varying degrees of itching. The causes of this condition are primarily believed to be associated with increased sebum secretion or changes in the chemical composition of the cortex. It is also related to the colonization and infection of Malassezia, stress, diet, deficiency of B vitamins, alcohol consumption, and other factors. The characteristic rash consists of follicular papules that expand and merge into dark red or yellow-red patches, covered with oily scales or crusts. Exudation, crusting, and erosion can occur, resulting in eczema-like changes.

What department should I go to for seborrheic dermatitis?

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic, papular, scaly superficial inflammatory skin disease that occurs in areas where sebum is excessively secreted. It is more common in adults and newborns, but can occur at any age. The main symptoms include follicular papules appearing on the scalp, face, chest, and back, which then merge into large, yellowish-red or dark red patches. These patches are covered with greasy scales and crusts, and may be accompanied by exudation, crusting, erosion, and eczema-like changes. In severe cases, it can spread throughout the body, causing diffuse erythema and significant scaling all over, along with varying degrees of itching. This disease is a chronic condition that can recur repeatedly. It is one of the most common diseases in dermatological practice. Therefore, patients with seborrheic dermatitis should consult a dermatologist.
