Okay, I'm kind of nervous because this is my first thread and I'm not sure if there may be one like it so.. bare with me.
Well the way I made my nose smaller was really simple. There is a product called NoseRight that squeezes your nose into a different shape, which is totally possible because the nose is made out of cartilage and is moldable.
I didn't use that product. i simply squeezed the sides of my nose together for a count of thirty and let go. There was a significant change in the size. Do this a few times a day and I'm sure the results will be at least semi-permanent if not better.
NOTE: I did not buy and use this product. I used my fingers which did exactly what the product did (in a shorter amount of time)
