According to the situation, it is caused by virus infection and low body immunity. Take some anti allergy, improve body immunity and antipruritic drugs orally. The treatment should be high, eat less spicy and stimulating food, eat more fresh fruits, and check regularly to understand the situation of the body.
First of all, we need to pay attention to local cleanliness and hygiene. Sometimes skin allergies, mosquito bites and skin rashes can also lead to some scars. We must pay attention to avoid scratching and irritation, and apply erythromycin ointment appropriately.
This situation may be caused by dermatitis or skin tissue damage caused by accidental injury. You can observe it first. If the skin tissue returns to normal after the festival, it may be trauma, but if it is dermatitis, it will occur repeatedly. During this period, pay attention not to eat spicy food. When it is stimulated, it is mainly light.
