There are various reasons for scars, but as you look at changes in color. There are reddish objects, brown ones, and white linear ones. Although red and brown ones if you can avoid getting ultraviolet rays, they will gradually get better gradually even if conservative treatments are done, but if it does not become so or if it is already white, it is quite difficult to improve with normal treatment I will not.
Our clinic sometimes treats such scars by using a fractional carbon dioxide laser made in the USA in collaboration with a university hospital where doctors are part-time staff, so if you are interested please ask .
