A scar is a mark that represents a wound to the skin. This kind of trauma may be caused by trauma or it may be necessary for surgery. However, due to the different degree of trauma, whether the healing process is smooth or not, and the different position of the wound on the human body, the scar size is obviously different. The cause of skin scar formation is skin defect caused by some trauma (such as surgery, car accident, scald, etc.). Please refer to: /u/3560728 195 for an effective method to remove scars.
