Scarring, also known as keloid scarring, is a special condition in which the body is left with some noticeable hyperplastic patches or keloid scars on the outside of the body after a minor trauma. People who suffer from keloid scarring are usually characterized by increasing scarring on the surface of the skin after external wounds have healed. These scars not only affect the appearance, but also localized pain, red and itchy skin, keloid contraction and other symptoms, and also affect the body’s active function. People with keloid scars should pay attention to avoiding bumping in general, and pay attention to careful care after surgery and laser and other treatments, because scar proliferation may be caused after surgery, and if keloid hyperplasia occurs, it can be treated with localized closure or skin abrasion method. When scarring occurs due to external injuries, it is recommended to go to the hospital and receive professional treatment from the doctor.
