There is no particularly good way except laser plastic surgery. Scars will appear when the dermis is injured. 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 improve it to some extent, but most of them are not ideal. People with scar constitution should prevent skin trauma, prohibit surgical resection, prohibit indiscriminate drug corrosion, and prevent the illness from getting worse.
