Mild atopic dermatitis can heal itself within a few hours. More severe atopic dermatitis takes longer to recover and may exceed 24 hours.
People with atopic dermatitis often have allergies and develop atopic dermatitis after exposure to an allergen, which manifests itself as itching, redness, swelling and hives. Mild atopic dermatitis can heal itself within a few hours, usually no more than 24 hours, but recovery from severe atopic dermatitis takes much longer and may exceed 24 hours.
Common allergens include dust, dust mites, animal hair, and pollen. People with allergies should minimize exposure to these allergens. If atopic dermatitis develops other uncomfortable symptoms or is delayed, you need to go to the hospital in time.
