She also went on to talk about her trip and her latest film 'Fighting With My Family'.
Some people loved her authenticity and her no-makeup look. They wrote comments like natural beauty, you are an amazing woman and you look more beautiful without make up then most people do with it on.
However, between all the nice comments, a few people left some nasty comments about her appearance.
Don't record yourself without makeup again please, a person wrote.
The actor clapped back at the criticism like a boss, sharing a screen shot of the comment from the person urging her to wear makeup on camera.
She posted a screen shot of the comment along with a caption that read, I shall continue to not wear makeup. Go f--k your self.
Her epic response was met with a lot of applause from a few fellow actors who have faced similar criticism.
Co-star Carice van Houten wrote, I get that too. F--K THAT.
'The Handmaids Tale' Ever Carradine commented, F--k that noise. You're perfect.
Meanwhile, fellow 'Game of Thrones' actor Gwendoline Christie extended her support with a series of heart emojis.
Another fellow 'Game of Thrones' actor, Emilia Clarke applauded her and commented, PREACH BEAUTIFUL WOMAN.
On the work front, Lena is all set to star in the eighth and final season of 'Games of Thrones', which premieres on HBO, April 14.
