Scar constitution is usually improved by preventing trauma or infection. After scar formation, it can be treated by drugs, laser irradiation, liquid nitrogen freezing or surgery. The specific analysis is as follows:

1. Prevention of trauma or infection: Patients should pay more attention to avoid skin trauma at ordinary times. If inflammation occurs, it should be controlled as soon as possible to reduce scar hyperplasia, which can improve scar constitution to some extent.

2. Drug therapy: Tranilast can be taken orally, combined with tretinoin preparation for external use, and can also inhibit scar hyperplasia. But patients need to strictly follow the doctor's advice.

3. Laser irradiation: Treating scars with different laser wavelengths? In this way, the epidermal reconstruction of scar can be achieved, the regeneration and remodeling of collagen tissue can be promoted, and the purpose of fading scar can be achieved.

4. Cryopreservation with liquid nitrogen: Cryopreservation with liquid nitrogen can promote the necrosis of scar tissue cells and remove the scar.

5. Surgical treatment: If the scar is large or at the joint, it needs to be removed by surgical resection or skin flap transplantation.

All the above methods are risky. You can go to a regular hospital and choose a professional doctor for surgery, which can reduce the risk and pay attention to postoperative care.
