There are a few options you have to improve the appearance of your scar. Lasers can be used to help blend the scar and reduce the redness in it. It will take a series of treatments will stepwise improvement with each treatment. The side effects are minimal when used in properly trained hands and the results can be very impressive without any cutting. Scar excision and revision is another option where the scar is cut out and re-stitched. The goal is to leave a better appearing scar in place of the one you have but the risks are higher including infection, scarring and displacement of your eyebrow. Good luck.
