Manifestations of seborrheic dermatitis
Seborrheic dermatitis, also known as seborrheic eczema, is a chronic papular and scaly superficial inflammatory skin disease that occurs in areas of sebaceous secretion. It may be accompanied by varying degrees of itching. It commonly affects areas rich in sebaceous glands such as the head, face, chest, and back. Initially, the skin lesions are follicular papules, which gradually merge into dark red or yellow-red plaques. These are covered with greasy scales or crusts, and might exhibit exudation, crusting, and erosion, showing eczematous changes. In severe cases, the lesions may become widespread throughout the body, with the skin appearing diffusely flushed and significantly flaky. This condition is then referred to as seborrheic erythroderma. The disease is chronic and recurrent.
What is the best treatment for seborrheic dermatitis?
Seborrheic dermatitis is a chronic papular and scaly superficial inflammatory skin disease that occurs in areas where sebum is secreted and may be accompanied by varying degrees of itching. Its treatment generally includes three aspects. The first is topical medication treatment, which primarily focuses on degreasing, anti-inflammatory, antibacterial, and anti-itch properties. Common medications include tacrolimus, pimecrolimus, compound miconazole cream, compound econazole cream, zinc oxide oil, furacyclin ointment, boric acid zinc oxide menthol ointment, etc. For the scalp, shampoos containing ketoconazole, selenium sulfide, or salicylic acid can be used. The second aspect involves oral medication, generally supplementing with vitamin B2, B6, compound vitamin B, or zinc-containing preparations. Antihistamines may be used when itching is severe, erythromycin or tetracycline for bacterial infections, and oral itraconazole for fungal infections or widespread lesions. The third aspect is to advise patients to maintain regular living habits, get enough sleep, regulate their diet, limit polysaccharides and high-fat diets, avoid spicy and stimulating foods, reduce alcohol consumption, and eat more vegetables and fruits, avoiding various mechanical irritations.
How is seborrheic dermatitis formed?

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.
What should pregnant women do about seborrheic dermatitis?

Pregnant women diagnosed with seborrheic dermatitis are generally treated primarily with topical medications. It is advisable to choose mild, safe ointments with low irritability for external application. Safe antibiotic ointments, traditional Chinese medicine ointments, or ointments primarily for moisturizing and repairing the skin barrier can be used. Specific medications should be used under the guidance of a doctor. Additionally, pregnant women should be informed to maintain a regular lifestyle, get enough sleep, limit diets high in polysaccharides and fats, avoid spicy and irritating foods, eat more vegetables and fruits, avoid various forms of mechanical irritation, and use less hot water and strongly alkaline soaps for bathing.
Can seborrheic dermatitis wear makeup?
Seborrheic dermatitis, also known as seborrheic eczema, is a chronic papular squamous superficial inflammatory skin disease that occurs in areas of sebum secretion and can be accompanied by varying degrees of itching. The causes of the disease are generally believed to be related to increased sebum secretion, changes in the chemical composition of sebum, and colonization and infection by Malassezia. Additionally, factors such as mental state, diet, deficiency in B vitamins, alcohol consumption, stress, fatigue, and infections can all variably affect the occurrence and development of the disease. Accordingly, in clinical practice, patients are advised to maintain a regular lifestyle, ensure adequate sleep, adjust their diet, limit intake of polysaccharides and fats, avoid spicy and irritating foods, abstain from alcohol, eat more vegetables and fruits, and avoid various irritants. Furthermore, makeup can potentially irritate the face, so it is generally recommended that patients with seborrheic dermatitis either do not wear makeup or minimize its use.
How to treat diaper rash dermatitis?
Diaper dermatitis is primarily a type of contact dermatitis that occurs because the diapers soaked with urine and feces are not changed in time. Decomposition materials in urine and feces irritate the skin, causing inflammation. The main treatment involves keeping the buttocks dry and changing diapers frequently. It is necessary to wash the buttocks, genital area, and surrounding skin with clean water daily, and to rinse the anus and surrounding skin with water after bowel movements. Diapers should be thoroughly rinsed with clean water and not wrapped with plastic on the outside. If using disposable diapers, choose ones that are soft, not rough, and breathable. If there is a bacterial or fungal infection, topical antibiotics or antifungal medications should be used. For mild cases with only redness, consider keeping the buttocks dry. In cases where there is significant erosion, some medications may be used for intervention. If there is skin redness, topical calamine lotion can be applied. If the diaper dermatitis is severe and the baby is fussy and uncomfortable, it is advised to visit a hospital for a doctor to provide treatment based on the specific condition of the baby.
Is seborrheic dermatitis itchy?
Seborrheic dermatitis, also known as seborrheic eczema, is a chronic papular scaly superficial inflammatory skin disease that occurs in areas of excessive sebum secretion. It is commonly found in areas rich in sebaceous glands, such as the head, face, and trunk. The characteristic skin lesions primarily consist of follicular papules that gradually merge into dark red or yellow-red patches, covered with greasy scales or crusts. There may be exudation, crusting, erosion, and eczematous changes. In severe cases, it can spread over the entire body, causing diffuse erythema and significant scaling. The condition may be accompanied by varying degrees of itching.

The difference between tinea capitis and seborrheic dermatitis
Tinea capitis and seborrheic dermatitis are both skin diseases, but they are very different.Firstly, the types of fungi that cause tinea capitis and seborrheic dermatitis are different. Tinea capitis is mainly caused by fungi such as Trichophyton violaceum and Trichophyton tonsurans, whereas seborrheic dermatitis is predominantly caused by Malassezia.Secondly, their clinical manifestations are also different. The clinical manifestations of seborrheic dermatitis are often less severe than those of tinea capitis.Finally, tinea capitis often does not heal by itself and requires professional treatment, while seborrheic dermatitis can heal on its own, but tends to recur frequently.
