Human skin is mainly composed of epidermis, dermis and subcutaneous tissue. Dermal is mainly composed of collagen secreted by fibroblast stem cells and fibroblast precursor cells. Collagen fibers that make up collagen are arranged neatly, keeping skin smooth, shiny, elastic and tough. Skin injury or infection, such as burns, scalds, etc. It causes dermal tissue defects and the loss of body parts composed of collagen, and organisms in the human body cannot completely repair the dermal and subcutaneous tissues with complex structures. So when the epidermis is torn and the dermis is injured, the wound can only be repaired by connective tissue. At this time, the collagen fibers that were originally arranged in order began to shrink, disorder, accumulate and break, and new capillaries and nerve fibers grew in the new connective tissue. Such dislocation and regeneration of collagen fibers make the healed skin uneven. At the same time, the blood circulation of injured skin becomes unstable, and the pigment of injured skin will mutate. The surface layer of skin can be repaired by the basic cells of epidermis, but it will also cause color changes, and it is difficult for the skin to return to its original shape and color.

If it is a skin transplant, it is not clear. Whether skin grafting can be done still has to be said. How to cover up the scar depends on seeing a doctor. Suggest to go to the Peace Hospital (authoritative), run away, work hard, and save face.

But if your friend has good skin, the color may not be too obvious. When the time comes, go to the whole face and it will be basically OK! Also, you have to be 18 years old or 18 years old to do it, because the face has not been shaped yet.
