I have steroid scars from a doctor different than the one who performed my rhinoplasty (for acne scars). They left me with fat atrophy and dents in my face. They weren't that noticeable, but after my rhino (in which skin was removed), they became very apparent. I would like to inject those areas with sterile, preservative free normal saline. Injections will be subdermal and intradermal. Would this be ok? Would it ruin my rhino results? I'm 7 months post op.
