The formation of scar is the product of self-repair of the body. When the body tissue, especially the skin tissue, is damaged to a certain extent, the wound surface first undergoes inflammatory reaction, such as white blood cells, macrophages, mast cells, etc. Infiltration and release of various cytokines, fibroblasts and myofibroblasts proliferate and synthesize a large amount of collagen and matrix, which leads to abnormal collagen metabolism and arrangement, abnormal matrix deposition, microcirculation and free radicals, and promotes the formation of scars.

For the treatment of scars, it is recommended to go to a regular dermatological hospital for a detailed examination, and then choose a suitable treatment method to achieve better results.
