Drugs: Intra-scar injections of 5-fluorouracil, glucocorticoids and other drugs can soften and flatten scars. 2. Laser: Carbon dioxide pulsed laser and ion beam laser can be used to remove scars by vaporizing and peeling off the uneven epidermal layer and stimulating the growth of subcutaneous collagen through thermal effect. 3. Freezing: through the lower temperature of liquid nitrogen freezing, destruction of scar tissue, so that the necrotic tissue off, can quickly get rid of scars. 4. Surgery: Excision and suture surgery, keloid contracture release surgery, skin grafting, etc. can be given. Patients with the need to remove scars are advised to go to the dermatology department of regular hospitals and receive reasonable and standardized treatment under the guidance of doctors.
