Can I have Plasma Pen / Fibroblast on my nose after rhinoplasty?

I had rhinoplasty 3.5 years ago. I am broadly happy with my nose but it still fluctuates a lot- some days it is small and sharp and others its bigger and more swollen. I guess I must have scar tissue left. I am thinking of having Plasma Pen / Fibroblast on my nose to try and tighten it as I have had it on other areas with good results in tightening the skin. Will this be ok or is there any danger of making the scar tissue/swelling worse? Thank you!
