Hey faggot, how about you include the whole quote.
It goes something like this:
No one would've called these girls, who become sorceresses later on, pretty because most of the time they come from the lowest classes of society. Then, they use magic to become hot as fuck. Which is how they look 24/7 until they die.
Yennefer is cannonically about 100 years old and Geralt can somewhat pierce through the illusion to see "eyes of an ugly girl".
In summary, don't cherry pick quotes nigger.
