Cuts can happen on the outside or inside of the lip. Health care providers sometimes use stitches to close a lip cut and help it heal. Some stitches dissolve on their own, but others need to be removed. A healing cut can get infected, so the health care provider cleaned it carefully. You can help to prevent infection by taking good care of the cut as it heals.
What should I expect as the cut heals? Slight redness or itchiness around the cut is normal. A small amount of bloody or clear fluid may ooze from the cut and dry to form a scab, which will eventually fall off. Most cuts will leave a small scar.
Why does a cut get a scar? When the deeper layer of the skin is injured, the body uses a protein (collagen) to help fill in the cut area. The filled-in area becomes a scar. A scar can form even if a cut is fixed with stitches. Over time, some scars fade or get smaller.
