Epidermis Injury & Scarring: What You Need to Know

The epidermis is the topmost layer of the skin. It is mostly made of dead cells and does not have any blood vessels or nerves. Therefore, an injury to the epidermis will not cause any pain or bleeding. Since there is no blood flow, the body cannot send healing cells to the affected area. As a result, the injury to the epidermis does not leave a scar.
