Nasal alar reduction does not require prosthesis, and there is definitely no side effect. I have been doing nose for 2 years, and now I can pinch, press and push at will. At that time, I was doing swelling on the tip of my nose and ear cartilage pad. I don't feel bad anyway. By the way, I had plastic surgery in the manger, Jie Fangbei. You can also go to several stores to compare.
