Scars are keloid scars, and there are many types of keloid scars, including hyperplastic keloid scars, atrophic keloid scars, etc. They can be removed through medication, physical therapy, and surgical treatment. 1. Medication: Patients can apply medication such as Mucopolysaccharide Polysulfate Cream and Silicone Gel as prescribed by the doctor, which can lighten and eliminate the effect of keloid scars. In addition, you can also follow the doctor’s instructions to inject glucocorticoids such as tretinoin, which can inhibit the proliferation of collagen fibers and help improve the scar. If the scar is atrophic, you need to choose hyaluronic acid filling treatment. 2. Physical therapy: laser treatment such as fractional laser can also be used to promote collagen repair and drug penetration, which can help repair the affected tissues and help remove the scar. 3. Surgery: Surgical excision can be used for complex, peri-articular scarring to remove the scar tissue. There are many ways to remove scarring, so patients are advised to go to regular hospitals and cooperate with doctors for standardized treatment.
