Crusta lactea, also known as infantile eczema or atopic dermatitis, is a skin condition that affects babies and young children. It is characterized by red, itchy, and scaly patches on the skin, typically occurring on the face, scalp, and limbs. There are several synonyms for crusta lactea, including milk crust, infantile seborrheic dermatitis, and cradle cap. These terms describe the same condition but may refer to a specific area of the body affected or the age of the person with the condition. Treatment for crusta lactea typically involves gentle skin care, such as frequent bathing with mild soap and the use of moisturizers. In severe cases, prescription medications may be necessary. It is important to seek medical advice if the condition worsens or does not improve with treatment.
