I tried using the blue one for 10 minutes while in the bath twice for the past 2 weeks and I noticed a huge difference. The bulbous part of my nose feels more malleable, while before it felt really thick, hard to squeeze. It is not uncomfortable to wear it anymore for more than 10 minutes. The pink one, on the other hand, can still be a bit uncomfortable before 10 minutes pass.
I noticed my nose looks more defined, especially from far. I was at the gym today squatting and looking at myself on the mirror and I could see that my nose looked different.
I am going to use the blue piece every time I am on the bath. I will try the pink one too. I still have two pieces of cotton on the pink one to avoid that lego shape indentation on my nose.
