Old scars, i.e., old keloid scars, generally cannot be completely removed after they appear, but they can be improved by medication, laser treatment and surgery.
1. Medication: For old scar, if scar proliferation is obvious, glucocorticoid injection such as Triamcinolone acetonide injection can be used to soften the scar and improve the appearance of the scar.
2. Laser treatment: At present, carbon dioxide fractional laser, erbium laser and other photoelectric treatments are commonly used to deal with keloid scars, which can improve the appearance of keloid scars by peeling off and stimulating the regeneration and rearrangement of the local collagen, but generally, it requires several times of treatments to achieve the desired results.
3. Surgery: If the scar is obvious and affects the appearance or function, and the conservative treatment is ineffective for a long period of time, the proliferating scar tissue can be removed through surgery and then reduced suture. However, surgery is an invasive operation, and there is a risk of re-formation of hyperplastic scar, after surgery, you need to follow the doctor’s instructions to standardize the anti-scar treatment.
Patients who wish to treat old scarring are advised to go to a regular hospital and follow the specialist’s advice to adopt an appropriate treatment plan according to the location and condition of the scar. Drugs should be used in accordance with medical advice, do not self-medication.
