I had rhinoplasty done an had a steroid injection several times throughout the first 2 years and results looked amazing. I have extremley thick skin and about 2 and a half years later i noticed my skin looked thick again and i couldnt really see the refinement anymore. I had a steroid injection on the 3rd year and it looked refined and good. I didnt have anymore injections until 5th year and there was no refinement. I just had one now and its now 7th year post op and no change. Scar tissue?
