A skill is something that can be learned, your looks are something that you are born with.
And while there is a skill to "beautifying up" people, that only works to a certain degree and can't change the looks you were born with, it can only enhance/hide them in parts.
But you can't learn to uncrook your nose just like you can't remove your acne scars trough learning or straighten out your ears. These things don't require learning a skill, they require surgical procedures you most likely can't perform on yourself even if you had the skills to do so.
