Suture wound scabs can wait until they fall off naturally. After suturing a wound, a scab will form as the epidermal cells gradually repair. Most of the scabs are formed around 7 days after the wound is closed. After the scabs are formed, they should not be torn off by hand, but should wait until the scabs fall off naturally. Otherwise, it may cause the wound to bleed again and leave a scar. In addition, after the suture wound scab, in order to promote the recovery of the scab, must pay attention to avoid touching water too early, otherwise it will easily lead to abnormal shedding of the scab, and may even cause infection. After suture wound, must pay attention to cooperate with the doctor, to take post-treatment, mainly to disinfect the wound area, to avoid causing infection.
