Allergic skin is mainly characterized by rough, dark red or obscure skin with fine scales and scattered papules. In clinical treatment, anti-allergic treatment is required, including oral Orotadine hydrochloride tablets, loratadine capsules, and in severe cases, compound glycyrrhetinic acid capsules and vitamin C chewable tablets. In terms of topical application, you can choose a mild and moisturizing topical ointment, such as vitamin E ointment or urea ointment to apply, while for lesions on the trunk and extremities, you can apply Denide cream, and for lesions on the face, armpits, groin, under the breast and other relatively thin and tender folds, you can apply butalbital hydroxy acid cream.
