Usually, you won't need stitches for your minor skin injury. Most minor scrapes and cuts can be treated with first aid and proper bandaging. However, certain skin injuries need to be treated with stitches. Wounds that are more than 1/4-inch deep, have wide edges, or have muscle protrusions require stitches.
Generally, burns, one type of skin injury, do not require stitches. However, a skin graft-or skin transplant-may be used to replace burned skin.
