Topical medication: patients with small old scars, you can follow the doctor’s instructions to choose to apply scar removal cream for relief, such as hydroquinone cream, azelaic acid cream, and so on. 2. Laser treatment: If the patient’s old scars are slightly atrophic in texture and slightly depressed. And the effect of drug treatment is not very satisfactory, patients can use laser treatment to stimulate the regeneration of subcutaneous elastic fibers and collagen fibers, so as to make the local scars get faded or get rid of the effect. 3. Surgery: If the patient’s scar is large and has obvious hyperplasia, the patient can use surgery to achieve the effect of removing old scars. If you want to get rid of old scars, it is recommended that you go to the hospital in time for examination and choose a suitable treatment under the guidance of your doctor. The use of drugs need to follow the doctor’s advice, not self-medication.
