Scars on the legs can not be removed, but can be lightened by medication, physical therapy, surgery and other ways. 1. Medication: For newly appeared scars, drugs such as silicone gel and compound heparin sodium allantoin gel can be used, which can inhibit the growth of fibroblasts and prevent the overgrowth of subcutaneous fibrous connective tissues and elastic fibrous tissues in order to inhibit the formation of keloid scars and soften the keloid scars, and medication is only useful for proliferative scars. 2. Physical therapy: carbon dioxide laser, erbium laser and other photoelectric treatment is suitable for the less severe scar without obvious dysfunction; radiotherapy is suitable for superficial hyperplastic scar. 3. Surgical treatment: For obvious scar or scar in special functional areas, surgical treatment can be considered, but there is still a possibility of forming obvious scar again, so caution is needed. It is recommended that patients with scars on the legs go to a regular hospital, according to their own situation, choose the appropriate treatment program, avoid private medication, so as not to cause adverse consequences.
