  Expert Comments

Atopic dermatitis is an inflammatory skin disease characterized by redness, swelling, itching, crusting and scaling. Most cases begin to develop 2 to 3 months after birth and usually improve at 3 to 5 years of age. When the disease occurs, prevent the baby from scratching the itchy area to avoid breaking the skin and causing infection.

What parents should do

1. Avoid allergic substances

For parents with allergic constitutions, especially those with a history of allergic dermatitis, it is best to breastfeed their babies for 6 months, and it is best to delay the addition of complementary foods, because the proteins in these foods can cause allergic reactions in the baby's gastrointestinal tract and cause allergic dermatitis. In terms of diet, unless it is known that a certain food is an allergen, there is no need to strictly avoid or restrict certain foods to avoid causing nutritional imbalance in children. Foods that should be avoided include: milk, soybeans, wheat, eggs and nuts, such as cashews, walnuts, peanuts, etc.

2. Avoid infection

Babies' nails should be trimmed short and kept clean to avoid bacteria breeding due to scratching, which may cause infection, worsen the condition and become difficult to control.

3. Keep your skin clean

Choose cotton, sweat-absorbent clothing for your baby. Keep it loose and avoid clothes that are too thick or tight. It is best to wash old clothes before wearing them. It is better to use natural detergents, and be sure to thoroughly rinse off the residual detergent with clean water. When bathing your baby, use less irritating bath gel. Consider using baby soap once every two or three days and then wash with clean water.

4. Keep your skin moisturized

Dry skin is a major feature of allergic dermatitis. The ability of the stratum corneum of children's skin to retain moisture is much worse than that of ordinary people. The situation is more serious in winter, so the use of lotion or moisturizer is very important. Keeping the skin moisturized can reduce itching and alleviate or cure symptoms. You need to apply moisturizer after taking a bath, and apply it more often when the weather is dry and cold or your skin is dry.
