Dermatitis and eczema are diseases of the same nature, both classified as hypersensitivity disorders. Their clinical symptoms manifest as pruritic papules and plaques all over the body, accompanied by scaling and varying degrees of itching. The triggering factors are multifaceted, including genetics, environment, metabolism, and more, necessitating the strengthening of skin barrier repair. Daily care is based on moisturizing, recommending the use of medical skincare products such as soft moisturizing creams, and providing symptomatic treatments such as anti-inflammatory and antihistamine to regulate immunity. Medications including oral ebastine tablets, total glucosides of paeony capsules, and tripterygium glycosides tablets, as well as topical tacrolimus ointment, are suggested. (The use of medications should be under the guidance of a physician.)
