Many options. There are many different ways to try to improve the appearance of scars. The best place to start is with a consultation with a dermatologist or plastic surgeon who can review the expected results with skin care, resurfacing procedures, injections or surgical techniques. Unfortunately this is often a difficult problem and you need to go in with the expectation of improvement, not perfection.
Improve, not remove. Scars cannot be removed but there is a large variety of techniques to improve their appearance, both surgical and non-surgical. They also improve with time. See a dermatologist or board-certified plastic surgeon to evaluate your options. Good luck!
