If the area of small nascent scar can use drug treatment and photoelectric treatment, if the area of large old scar can be photoelectric treatment and surgery. 1. Medication: For newborn hyperplastic scar, drugs such as silicone gel can be used externally to inhibit scar proliferation, while old hyperplastic scar can be injected locally with scar softening drugs such as Triamcinolone acetonide to improve the appearance. 2. Photoelectric treatment: commonly used carbon dioxide laser, erbium laser, dye laser and so on. 3. Surgery: for depressed scar, fat filling surgery can be used to improve the appearance of depression; old scar of suitable size or special parts can be treated by surgical excision combined with local flap transplantation, but the surgery is still invasive, and patients need to be vigilant about the possibility of re-formation of keloid scars.
