The scars on the body could be of many reasons because of a surgery or an old injury. Many people tend to have scars from their childhood injuries, which hardly go from their skin. Scars develop when the continuity of the skin tends to break, due to injuries. Sometimes even a simple cut may leave the scar on your skin. Scars are not side effects or are concerned with any physical ailment, but many people do not like it because of the aesthetic concerns over it or may leave some psychological impact reminding them of the trauma if in case it was a serious one which need not be reminded to the person.
