The best time to repair the scars left after the stitches needs to be based on the specific repair method, and should be analyzed specifically, not generalized. Scars are usually left after stitches, depending on the size and depth of the wound and whether or not you have a scarred body, the size of the scar will be determined at a later stage. If the repair is conservative, it is usually recommended to wait for the wound to remove the stitches and the local skin to return to normal, the optimal repair time is usually about 3 days, the patient can use scar cream topical application to prevent the formation of scars or inhibit the growth of scars. If the scar is more obvious, patients need to be treated by surgical excision combined with radiotherapy, which can significantly relieve hyperplastic scars, and is generally recommended to be repaired after 1-2 years. During the recovery period, itching, pain and other discomforts may occur, patients should try to avoid repeated scratching to stimulate the local skin and scars, and at the same time adhere to the topical scar cream, which can reduce the proliferation of scars.
