Scars on the skin can be removed with topical ointment, hormonal closure, and physical therapy. 1. The ointments to remove scars include compound heparin sodium allantoin gel and mucopolysaccharide polysulfate cream, which have a longer treatment period. 2. Hormonal closure therapy refers to the use of glucocorticoid injections into the scar, you can use tretinoin injection, compound betamethasone injection and so on. 3. Physical therapy mainly refers to photoelectric treatment, commonly used carbon dioxide laser or fractional laser.
