The more itchy the skin is, how does that happen?

It is necessary to judge what is going on according to the appearance of the skin. If there is nothing growing on the surface of the skin, it is mainly itching, and itching also shows frequent recurrence after scratching, then skin itching may be caused by allergic factors. Generally speaking, this skin itching may be caused by ingestion of certain allergic substances, or by some other factors. Cetirizine tablets or loratadine tablets can be taken orally. If the itchy skin is accompanied by dry dander, and the dander can be felt relatively increased after scratching, then it may be dry dermatitis, which is caused by the decrease of local hydration degree after the dry stratum corneum. You can choose to take oral desensitizing drugs at the same time, and apply some moisturizers externally, such as loratadine tablets orally and hyaluronic acid gel for external use. If there are red papules and blisters in the itchy place, it may be eczematous dermatitis. Can be topical glucocorticoid topical ointment.
