Patients can apply topical scar removal medications, such as scar itch softening cream, compound heparin sodium allantoin gel, silicone gel, etc., which can change the pathological process of scars and promote scar repair. For patients whose medication is not effective, intra-scar injections, laser, cryotherapy, radiation therapy or surgery can be chosen, all of which can help scar repair.

The scar softening period is usually 3-6 months, during which patients should reduce the stimulation of local tissues, quit smoking and alcohol, eat a light diet, and eat less spicy and stimulating food.
