At present, there is no particularly good method to treat scars. You can try to apply some ointments such as vitamin E cream, polysulfonate mucopolysaccharide cream, asiaticoside cream and allantoin cream to a certain extent, but most of them are not completely satisfied. People with scar constitution should prevent skin trauma, prohibit surgical resection, prohibit indiscriminate drug corrosion, and prevent the condition from getting worse.
