Generally speaking, if it is only a slight abrasion of the epidermis, it is not necessary to use a bandage. Just smear it with iodine or alcohol to prevent infection. You can also apply a thin layer of purple syrup, so that after about two or three days, the wound will become crusted and dry.
If the skin wound is relatively deep and unconditionally treated, rinse the wound with clean water, and then simply bandage it with a bandage. But the package time can not be too long, it is best not to exceed two days.
When using, tear off the package, apply the absorbent pad in the middle to the wound, then tear off the covering film at both ends and fix the position with tape.
