Any good tips for scar removal?

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!

Hard to know: Once a scar , always a scar. Many scars can be made less visible with various topical agents, lasers, and surgical scar revision, but complete removal is impossible. It also depends on where the scar is located. For example when people have cosmetic eyelid surgery the scars are almost invisible when healing is complete. The is one of the few areas where this is true.
