Moisturizing measures for dry skin need to be based on the triggering cause of dry skin. If the dryness of the skin is simply seasonal or caused by excessive bathing in the elderly, topical application of moisturizing ointment is sufficient, for example, 10% urea cream can be applied topically. If the dryness is high in some areas, you can also apply 20% urea cream or salicylic acid ointment. Of course, there are locations where dryness is less pronounced, you can also apply vitamin E cream, or mucopolysaccharide polysulfate cream, etc. If the dry skin is accompanied by obvious itching symptoms, the patient also needs to take oral antihistamines appropriately, such as levocetirizine hydrochloride and epalmatine by mouth as appropriate.
