Scars are keloid scars. Keloid itching can be improved through general treatment, medication and phototherapy. 1. General treatment: For patients with itchy scars, they should not scratch or pick at the affected area to avoid damage to the affected area, in order to prevent breakage and infection. 2. Medication: For patients with itchy scars, silicone gel, compound heparin sodium allantoin gel and other medications need to be applied under the guidance of a doctor, which can inhibit and lighten the scar and improve the discomfort of itching. Glucocorticoid drugs such as halometasone and dexamethasone can also be applied as prescribed by the doctor, which can help inhibit scarring and relieve itching. 3. Photoelectricity treatment: commonly used dye laser treatment, through high-energy laser action on hemoglobin, can destroy the capillaries at the scar tissue, which can help soften and inhibit scarring and promote inflammation and other efficacy, and then achieve the purpose of itching. If scar itching occurs, it is recommended that the patient go to a regular hospital and cooperate with the doctor for standardized treatment.
