After skin injury, it will go through inflammation, proliferation, remodeling and other stages. Surgical scars are more likely to form these two kinds of scars. In one case, inflammation stimulates the proliferation of fibroblasts, releasing a large amount of collagen and accumulating to form hypertrophic scars. In another case, wound injury leads to the loss of collagen and the formation of concave scars. Skin damage to the product layer will leave scars. So the operation will leave scars. However, scars are not diseases. If the appearance of scars is not ugly and does not affect the image, then scars are not a problem.
Laser can stimulate the cells in the scar area of the patient and help the collagen regeneration in the affected area.
