I didn't know, but I think I know why everyone is trying again and again. I used ear cartilage, and it was really high and pretty for a week, but as it went on, the tip of my nose was absorbed, so it was really the same as before.. haha Honestly, my nose was just normal before, so why did I do it if it's like this? I feel like I just wasted my money. I should have just snorted. And just looking at the reviews, the tip of my nose is falling off more and more, and it's hard to find someone who can maintain that pretty nose. I'm so jealous of people with pretty and small noses. I was thinking about getting it, but then I thought I'd end up falling into a bad luck addiction, so I just told myself to live with it. I wonder if there really is an immutable law. People who are thinking about nose surgery after reading this post, think carefully. Even if you look pretty at first, it's really rare for your nose to stay the same.
