Making your skin clearer is surely possible...I too dreamed of a smaller nose..I totally forgot about it
And some months later when I looked at the mirror, my nose did look a little thinner nd better.
I dont know how, but it really did work..might be because of the weight I lost or because of my tighter and better skin .

Moreover the structure of the human skull is the same.
The skin and the flesh in your face makes all the difference. Observe a kid now and after five years. His looks and the structure of his face change considerably. So its definitely possible
