The product is used in combination with surgical treatment. Generally, it is aimed at old scars and operations that are easy to leave scars. It will be used in the clinical treatment of burn department of Xijing Hospital. At present, most of them are imported brands, and they can only be bought through large import and export medical equipment companies or burn departments or plastic surgery in regular hospitals. Moreover, hospitals generally only treat patients and do not sell them to the outside world. If you want to treat scars, I suggest you go to the dermatology department of the Second Affiliated Hospital of Xi Jiaotong University.
