Generally the differences between male and female faces apply to all ethnic groups equally. However it is easy to mistake an ethnic difference for a gender difference and it often seems to be that non-European faces are compared to white European faces as if white European faces were somehow the standard or an ideal. This is completely wrong and I always resist it. In my opinion, a surgeon should always consider what the normal feminine dimensions would be for a face of your own ethnicity.
For example: men have wider jaws than women but East Asian women have wider jaws than white European women so if you compare an East Asian woman's jaw with a white European woman's jaw it might seem to be too wide but if you compared her jaw width to the average East Asian male, her jaw width would be within normal female ranges.
Another example would be with noses - men have wider noses than women but people of African (sub-Saharan Africa) ancestry usually have wider noses than white Europeans so if you compare the nose of an African woman to a European woman, her nose would seem to be masculinely wide. But again, when compared to an African man, her nose is within normal female ranges.
Trying to force features into the norms of a completely different ethnicity can make for an unnatural looking result. An example of this would be someone like Latoyah Jackson - if you see pictures of her before rhinoplasty, she has a typically African nose that suits her face. Now her nose is narrow and pointed like a white European nose. In my opinion the European nose shape does not really suit her face and the nose itself also looks very artificial because the surgery has been too extreme - you just can't push features that far surgically without it looking unnatural. I am not saying that she asked her surgeon for a European nose - I was not there and do not know what her motivations were but it is a European nose whether she intended it to be or not.
It may be that she prefers her nose as it is now and I very much respect that and of course personal taste comes into these things but my personal approach to facial surgery is to aim for a very natural look and that means not straying too far from the apparent ethnicity of your face.
