1. People with scarred constitution should try to reduce the chance of injury. When suffering from acne, folliculitis, or boils, do not forcefully squeeze, and do not use strongly irritating drugs such as strong acids and alkalis to avoid leaving depressed or hypertrophic scars. Medication should be used safely under the guidance of a doctor.

2. Patients with emergency trauma, if their lives are in danger, should seek a plastic surgeon for debridement and suturing or tissue defect repair as much as possible to minimize scarring factors.

3. Plastic surgery should strictly abide by the principle of surgical asepsis. The surgical incision should be along the direction of skin lines or skin tension lines and should be located in a relatively hidden part. The operator should be gentle, the instruments should be sharp, and thin needles and threads should be used as much as possible. Keep the wound clean and free of foreign matter. The suturing should be in accurate position and adhere to the principle of tension-free suturing.

4. Patients should avoid sun exposure after surgery and eat less spicy and soy foods. You should understand the common sense of scar formation, prevention and treatment, and actively cooperate with doctors for treatment.
