The answer is mainly…COVID-19. Shooting for the 2nd series was scheduled
for February 2020. At that time, the actress who plays her, Freya Allen, was an
18-year-old child.
However, due to the global pandemic, the shooting was extended until March
2021. By that time, she was almost 20. The changes you see in her appearance
are mostly the natural growth and changes that a human body goes through.
Also, you may have noticed her eyebrows are now dark, whereas in season
1 they had been bleached white.
In an interview, the actress told Collider: “I was the one who said,
‘I’m so sorry, but if we are’ — which hopefully we will — ‘get to do many more
seasons, I am not going to have any eyebrows left if they are bleached every
day of The Witcher. They won’t be there anymore. And also it requires you
spending however many months walking around in the streets looking like you are
off Mars.”
