Milk` is a problem that I’m afraid is encountered every day in the clinic. Many times, milk ` is the common name for infant eczema, but some seborrheic dermatitis is also called milk `, which is easy to confuse, but in fact they are two completely different diseases. Eczema, known as eczema in English, is a Greek word meaning “boiling over” and is characterized by erythema, edema and scaling, often accompanied by crusting and in severe cases blisters. Infantile eczema occurs in about 10-15% of infants and is most common on the cheeks and joints of the extremities. Eczema is caused by inadequate production of ceramides by skin cells. Ceramides are important for building the skin barrier, and when deficient, the skin cannot retain moisture and tends to dry out. In addition, genetics and microbial invasion on the skin are also very important causes. Most eczema disappears before school age, and a few persist into adulthood. Factors that trigger eczema are Dry skin: prone to flare-ups in the fall and winter. Irritants: including woolen clothing, perfumes, laundry detergents, soaps, etc. Heat or sweating: can make eczema worse. Allergens: xenobiotics in food, such as shrimp, eggs, milk, peanuts, etc. Treatment of eczema The lesions of seborrheic dermatitis are characterized by an erythematous base covered with greasy yellow scales, accompanied by mild itching. The disease usually starts within two months after birth and disappears within eight months. The most common sites of involvement are the face, scalp, eyelids, eyebrows, behind the ears, etc., and the neck, axillae and groin folds can also be involved.
