Wound scarring occurs when serum and fibrin exuded from the wound clump together during the healing process. It is possible to take a shower after the wound has scabbed over, but it is important to avoid the scabbed area when showering. Because the wound scab is only a temporary healing, sewage and other water may enter under the scab through the gap between the scab and the skin wound, which can easily cause infection within the scab and lead to pus or fluid accumulation in the wound. When bathing, we should pay attention to protect the local wound, avoid contact with sewage and other parts of the scab, you can use plastic wrap and other carefully wrapped, wrapped tightly wound, to avoid sewage and other stimulation of the wound to cause infection. After each bath, you can use povidone-iodine and other drugs to sterilize and disinfect the local wound to play a protective role. When the wound scab falls off, the wound subcutaneous tissue and skin completely healed, you can take a normal bath. If you feel unwell, you should go to the hospital in time to avoid delaying your condition or causing adverse reactions.
