A short YouTube presentation by Hallie Bulkin explaining that nasal expansion increases internal dimensions (distance between nasal walls) but often does not make the nose look wider externally because the overlying maxilla and skin are pushed forward, supplying more skin and masking the apparent expansion; results include perceived fullness and more defined cheekbones rather than an obviously wider nose.
So while the internal structure of the nose, it changes, it increases. So this size between the two walls. But the skin, the outer, this superficial part, which is covered with the skin, it doesn't show the expansion itself. So you will not tell that you expanded your nose and it is 5 millimeters wider than it used to be. Why? Because while expanding the internal nasal structure, this outer surface of the maxilla is also pushed forward. So that brings more skin, and that kind of annihilates that expansion result by just the perception of more fullness everywhere. So that squeezes the nose, the air layer of the nose, this cartilagenous part of the nose. So you don't look like your nose is expanded too much, you just show more fullness and more defined cheekbones.
