I am an Asian man and have significantly thickened nasal skin. I am wondering how my nose job might differ from that of a Caucasian.
As Asians age, it is very common to develop very thick nasal skin. In general, compared to most Caucasian skin, the Asian nasal skin is thicker and the anatomy of the nose is different. The biggest difference would be that the thickened nasal skin will not show the cartilage underneath. It can be reduced in size, however, and become more aesthetically pleasing in appearance.
In a Caucasian nose, the skin is often a lot thinner and will allow every little change that is made to the nose to be visible, which may be an issue if the healing does not occur properly.
Imagine, as an example, putting a thick duvet on a bed and underneath that duvet is a small box. With thickened nasal skin, just as with a thick duvet, you will be able to see there is something on the bed but you will not know exactly what it is. If you drape just a sheet over the bed and box, you will be able to see the box with the actual contours.
That is a good way to think about the differences between the thickened nasal skin, whether in an Asian person or other ethnicity, in comparison to a thinner nasal skin. Of note, Caucasian individuals might also have very think nasal skin.
