Scars will not be completely eliminated once they appear in people with scarred skin, but the appearance of scars can be improved through medication, physical and surgical methods. 1. Drugs: In the early stage of scar formation, you can use drugs to treat scars, mainly applying sodium heparin sodium allantoin gel, silicone ointment, and so on, but also can be injected with glucocorticoid drugs, such as triamcinolone acetate suspension, hydrocortisone acetate suspension, and can be injected with 5-Fu, and so on. 2. Physical: Physical methods include laser therapy, pressure therapy, cryotherapy and so on. 3. Surgery: If the effect of the above conservative treatment is not obvious or the severe hyperplastic scar affects the function, surgical excision can be carried out, and additional radiation therapy or hormone local sealing should be applied after surgery. Commonly used surgical methods include keloid contracture release, skin grafting or localized skin flap transplantation. If you have scars, you need to go to a regular hospital as soon as possible, and the specialist doctor will formulate an individualized diagnosis and treatment plan according to the specific condition, so as not to delay the condition.
