Because some people don't know that they are patients with scar constitution, after some operations, scars will continue to increase and expand, forming a knot in one's heart. This is because people with scar constitution are too sensitive. People with this constitution will grow back even if scar hyperplasia is cut, and the area is larger. For people with scar constitution, we do not recommend surgical removal of scars. The scars on the skin of some patients protrude from the epidermis, accompanied by itching and pain, and the texture becomes hard, the color becomes darker, and the area of the scars continues to expand outward. Most of these cases are hypertrophic scars. Mild hypertrophic scars can be controlled by drugs and bandages, and severe ones must be removed by surgery. There are only one in a thousand people with scar constitution, so except those with scar constitution, most scars can be directly removed by surgery.
