Seborrheic dermatitis refers to a type of inflammatory skin disease that occurs in areas where sebum secretion is abundant, including the face, chest, and back. These areas tend to be oilier and are prone to developing erythema and greasy scales. If the seborrheic dermatitis is of the dry type, it may also be accompanied by symptoms of peeling skin. The condition commonly affects individuals with hyperactive sebaceous glands, typically those with oily skin. Some people have combination skin that is also prone to oiliness, making them susceptible to seborheic dermatitis, often due to improper skin care. Dietary habits, frequent late nights, and consuming overly spicy or greasy foods can also lead to the development of seborrheic dermatitis.

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.

It can be accompanied by varying degrees of itching and commonly affects areas such as the face and trunk, where sebaceous glands are abundant. It is more frequently seen in adults and newborns. The exact cause of the disease is still not completely understood. It is generally believed to be related to increased sebum secretion, changes in the chemical composition of sebum, and colonization and infection by Malassezia yeasts. Factors like stress, diet, deficiency of B vitamins, and alcohol consumption can also influence the occurrence and development of the disease. Therefore, seborrheic dermatitis is not contagious.

Seborrheic dermatitis, also known as seborrheic eczema, is a chronic, superficial inflammatory skin disease characterized by papular and scaly eruptions that occur in areas with excess sebum production. It often causes varying degrees of itching and commonly affects areas rich in sebaceous glands, such as the head, face, and trunk, and is more frequently seen in adults and newborns. The exact cause of this condition is still unclear; it is generally considered to be related to sebum secretion and changes in its chemical composition. Additionally, colonization and infection by Malassezia, as well as several other factors such as stress, diet, deficiency in B vitamins, and alcohol consumption, can also influence the occurrence and development of the disease. Since the causal factors are not well understood and there are many triggering factors, the disease has a chronic course and can recur repeatedly. Although seborrheic dermatitis can be cured, it can still recur.
