At present, the best method is laser scar removal, mainly using the thermal effect of laser. The high-power laser used in laser scar removal has high energy, which will produce high fever and damage the tissues outside the scar. Depending on the radiation dose, the themes of erythema, blisters, solidification, carbonization and vaporization can be changed. In medicine, the focused laser is made into a "light knife" for cutting scars. The incision is neat and clean, with less bleeding, clear vision and accurate treatment site.

Laser can solve skin scars such as acne scars very well. While effective treatment, it can also reduce the formation of acne scars.
