Eczema is an intensely itchy skin inflammation reaction caused by a variety of factors, including both external and internal causes. External factors include environmental climate changes, sunlight exposure, animal fur, cosmetics, etc. Internal factors mainly involve food, endocrine disorders, stress, and more. Treatment primarily targets these causes. If caused by external factors, efforts should be made to avoid them. If related to food allergies, such as milk or eggs, these allergenic foods should be avoided. Treatment can also include the use of anti-allergic ointments, commonly corticosteroid ointments, as well as oral anti-allergy medications to assist in treatment.
