How can I help flatten out and lighten skin graft on my nose?

I had a skin graft surgery from a trauma injury to my nose. My surgeon used the back of my ears as the donor site. The injury caused me to need parts of my septum and nostril replaced. The skin graft appears to feel much softer then the rest of my nose and is noticeable dark and raised, especially the nostril area. This surgery was about 5 months ago now. I've been using silicone scar sheet and gel as well as sunscreen when I'm not wearing the scar sheets. Any suggestions of what I can do?
