Is it possible to change your appearance with affirmations/subliminal audios/Law of attraction? The short answer is yes.
It's very hard to believe and sometimes even I was skeptic about this even having seen changes myself and other people saw changes in me. But I just sat and thought "Wow, really?!"
Why are these changes possible? Because as I mentioned in previous posts. We can change anything we want just with the power of our mind. But because we were "programmed" a certain way, dna and all that. We need to be "reprogrammed" for these changes to occur.
Also, everything is energy, including ourselves. Nothing is solid to the point it can't be changed. Energy is constantly changing. I made a post about this, If you haven read it, you can do so here: https://steemit.com/science/@latte.mp3/law-of-attraction-law-of-vibration
It takes time for these changes to happen and because people don't see the change they want straight away (attachment) they instantly think it doesn't work (limiting beliefs). All these can be resolved though.
If you really believe you can change your physical appearance, like for example, your nose shape. Then it will change. All it takes is belief, and a lot of patience.
