I'll give you a few ways to try
A: Don't catch too much, because catching too much will aggravate skin diseases. Many patients scratch the itchy part of the skin for a moment's pleasure until the skin bleeds, and the result is that the more they scratch, the more itchy they become, forming a vicious circle. If they scratch their skin frequently, they may develop eczema-like changes. So don't buy hormone antipruritic drugs, such as skin relaxants and Pikang cream.
B: Bathing: Many people are afraid that the bath is not clean. Soap is repeatedly rubbed in hot water, so that the oil on the skin surface is washed off repeatedly, resulting in dry skin. In fact, soap and shower gel are used at most twice a week in winter, and it is ok to wash them with water at ordinary times. It is best to apply moisturizing cream after bathing to reduce water evaporation.
C: Taboo: Try not to eat fish, shrimp, wine, peppers and other foods, and try not to touch articles containing chemical components.
D: Treatment: Generally, after the diagnosis, if it is not serious, skin care products should be used externally, and attention should be paid to supplementing water and vitamins to prevent dryness. For severe cases, oral allergy (kairitan loratadine) and sedation (doxepin) are enough.
The above is the personal experience of dermatological consultation, and I sincerely answer it for you. Don't copy.
