Seborrheic dermatitis is a chronic papular and scaly superficial inflammatory skin disease that occurs in areas where sebum is secreted. It is often accompanied by varying degrees of itching and commonly affects areas with abundant sebaceous glands, such as the head, face, and trunk. The disease is chronic and may recur periodically. Treatment generally includes three aspects: Firstly, patients should be informed to maintain a regular lifestyle, get sufficient sleep, avoid various mechanical irritations, use less hot water and strongly alkaline soaps for bathing, and pay attention to their diet. They should try to reduce or limit the intake of polysaccharides, alcohol, and spicy foods, while consuming more vegetables and fruits. Secondly, topical medications are used, generally choosing formulations that contain corticosteroids and antifungal agents, such as compound miconazole and compound econazole. If the response is inadequate, calcineurin inhibitors such as tacrolimus and pimecrolimus can be used. Zinc oxide ointment, boric acid and zinc oxide camphor ointment, and erythromycin ointment can be used when there are exuding erosions. If the scalp is affected, shampoos containing ketoconazole or selenium sulfide may be used. Thirdly, oral medication treatments typically include supplementation with B vitamins such as vitamin B2, B6, complex B vitamins, or zinc-containing formulations. For severe itching, antihistamines can be taken orally. Oral itraconazole may be used for fungal infections or widespread lesions. Tetracycline or erythromycin may be used for bacterial infections.

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.

How to treat infant seborrheic dermatitis

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic papular squamous superficial inflammatory skin disease that occurs in areas of sebum secretion. It is more commonly found in adults and newborns and can be accompanied by varying degrees of itching. In infants, seborrheic dermatitis generally occurs from the 2nd to the 10th week after birth, with common sites being the scalp, face, nasolabial folds, nasal hair area, around the ears, and in skin folds. The rash typically appears as greasy red patches, or may be covered with greasy gray-yellow or brown-yellow thick crusts. In severe cases, there might be erosion and exudation. The condition generally diminishes or even heals within two months, though in very rare cases, the rash may suddenly spread throughout the body, causing diffuse erythema and significant desquamation. This is known as seborrheic erythroderma, which represents a severe stage of the disease. Treatment mainly involves the use of topical medications, focusing on mild, safe, and low-irritant drugs for application. Commonly used medications include zinc oxide oil, antibiotic ointments, traditional Chinese medicine ointments, tacrolimus ointment, and pimecrolimus cream. Additionally, it is important to advise the parents to ensure the baby has a regular lifestyle with sufficient sleep and to avoid various mechanical irritations. It is also recommended to use less hot water and harsh alkaline soaps for bathing.

What are the symptoms of seborrheic dermatitis?

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic, superficial inflammatory skin disease characterized by papular and scaly inflammation that occurs in areas of sebum secretion. It can be associated with varying degrees of itching and is commonly seen in adults and newborns. The main symptoms include hair follicle papules appearing in areas of sebum secretion such as the scalp, face, chest, and back, which then merge into dark red or yellow-red patches. These patches are covered with greasy scales and crusts, which can lead to exudation, crusting, and erosion, manifesting eczematous changes. In severe cases, the lesions can spread throughout the body, leading to diffuse erythema and significant desquamation. At this stage, it is referred to as seborrheic erythroderma. This condition is chronic and may have recurrent episodes.

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 Seborrheic Dermatitis

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic papular scaly superficial inflammatory skin disease that occurs in areas with excess sebum secretion. It can be accompanied by varying degrees of itching and typically occurs in areas with abundant sebaceous glands such as the scalp, face, chest, and back. The treatment generally includes three aspects: The first aspect involves advising patients to maintain a regular lifestyle, get sufficient sleep, avoid various mechanical stimuli, use less hot water and soap with high alkalinity for bathing, and pay attention to their diet by limiting and reducing the intake of polysaccharides and fats, alcohol, and spicy and irritating foods, while consuming more fruits and vegetables. The second aspect is the treatment with topical medications. Commonly used medications include mixed preparations containing corticosteroids and antifungal drugs, such as compound miconazole and compound econazole. If the effect is unsatisfactory, topical calcineurin inhibitors such as pimecrolimus or tacrolimus can be used. If there is exudation or erosion, zinc oxide ointment or erythromycin ointment can be chosen. For scalp lesions, shampoos containing ketoconazole or selenium sulfide can be used. The third aspect is the treatment with oral medications, which generally includes supplementation with B vitamins such as vitamin B2, vitamin B6, and compound vitamin B, or zinc-containing preparations.
