Experts said: The treatment of protruding scars on the face will be based on the cause of scar formation. Generally speaking, effective treatments for protruding scars mainly include surgery (surgical skin grafting, burial). dilator), grinding, physical compression therapy, drug therapy, etc. 1. Physical compression therapy: suitable for early treatment and prevention of scars. The application is often limited due to the friction between the pressure sleeve and the scar surface, resulting in epidermal damage, discomfort during use, and swelling of the extremities of the limbs. 2. Drug therapy: Currently, long-acting corticosteroids and anti-tumor drugs are mainly used to treat hypertrophic scars and keloids. However, simple treatment with drugs (especially hormonal drugs) has greater side effects. 3. Surgery: Surgical skin grafting and buried expanders are often used to treat severe scars that affect physiological functions. The therapeutic effect is relatively obvious; however, it requires high surgical skills, and there is a risk of scar hyperplasia in new surgical wounds, especially scars. pimple. 4. Grinding: Mainly uses microcrystal grinding machine, laser, ultra-high-end and other equipment to "grind" the scar surface to make the scar surface flat. It is suitable for the treatment of superficial scars, but it can easily cause epidermal damage and lead to deposition or loss of skin pigmentation after treatment. The surgical effect has a great relationship with the doctor's technical level. 5. Radiotherapy: It uses X-rays to directly irradiate scar tissue, and is mainly used for the treatment of keloids. However, radiation therapy can easily cause radiation damage. 6. Injection scar softening needle: suitable for hypertrophic scars, keloids and strip hyperplasia after surgery. 7. Laser treatment: Using advanced laser equipment, selecting specific wavelengths and pulse widths of laser irradiation, it has a significant effect on pigmentation after scar repair.
