Method 1: Cryotherapy. It is to apply a low temperature below the critical temperature to the tissue of skin pigment scar cells, thus effectively killing cells and hindering the growth of scar cells.

Method 2: Stress therapy. This method is very simple, that is, dressing the wound with ordinary elastic bandage to prevent scar hyperplasia. After adapting to the pressure, it was gradually extended to 24 hours of continuous pressure, lasting for 5 months to 12 months until the scar became flat, soft and white.

Method 3: Physical therapy. It is the use of sound, light, electricity, heat and other physical factors to treat scars, which has a slow effect and needs long-term persistence.
