What can be done to minimize the appearance of a raised alarplasty scar? over 1 year post op (photo)

How do I get rid of this raised, ropey scar that is a result of an alarplasty? The scar appeared about 6 months after alarplasty and is now a year and a half old. The scar was itchy at first and had pain, but now it no longer does. I have used silicone gel and silicone scar strips but I’m looking for something that will give more cosmetic improvements.
