The scar at the top of your nose does appear wide, depressed and lighter in color than the rest of your skin. I would recommend a scar revision to remove the scar and ideally replace it with a thin, flat scar that would be less noticeable than the one you currently have.
There is no way to definitively and permanently remove scars--that is the biologic way that the human body heals. Often however, a dermatologist or plastic surgeon with experience treating scars can help to diminish their appearance typically using a combination of approaches. Sometimes fractional laser treatments can improve the appearance of scars and make them less noticeable. It is a little hard to tell from this photo but it does appear that your scar is slightly wide and hypopigmented. You very well may benefit from a scar revision where the old scar is cut out and a new, nicer scar is made followed by an aggressive scar care program afterwards (taping, sun avoidance, scar massage, and laser treatments). A plastic surgeon can definitely help you with that but make sure you consult with one that is board certified/eligible and has experience treating scars!
