What can I do for better circulation and healing for the tip of my 8 months nose post-rhinoplasty?

I had a septoplasty in 2019 and then had another septoplasty/rhinoplasty in 2021. Once the cast came of, I noticed the tip was red and irritated. 8 months later the shape of my nose looks good, but the tip looks blueish - especially when it's cold out. It seems to be a vascular problem. When I touch the tip the color blanches. My doctor suggested BBL. I was wondering what else i can do? Will it heal on its own?
