The skin has a barrier function that prevents the invasion of bacteria, viruses, house dust, pollen, etc.

If the skin barrier is breached for some reason, an immune response will occur in the skin to protect itself from invading foreign enemies. In the process, bioactive substances are released, causing inflammation, resulting in small blisters (small blisters) and papules (red papules).

If the symptoms such as itching are mild, it is an immune reaction and may heal spontaneously even if left alone.

However, if it becomes chronic, it may not be cured easily, so if it does not cure after a day or two, it is recommended that you consult a dermatologist.

It may be seborrheic dermatitis caused by irritation caused by excessive secretion of sebaceous glands, contact dermatitis caused by contact with some substance, or intrinsic eczema caused by allergic reaction to food or virus. There are various types of eczema, such as heat rash and dyshidrosis caused by irritation caused by the phenomenon of sweat retention.
