The Stranger Things actress burst onto the Hollywood scene as a twelve-year-old when she first started playing the character Eleven on the popular sci-fi Netflix drama.
In the podcast, she candidly spoke about how "gross" it was the way media, especially social media, "sexualized" her after turning 18.
"I deal with the same things any 18-year-old is dealing with, navigating being an adult and having relationships and friendships, and it's all of those things," she said.
But her circumstances were very different compared to that of other girls her age.
"Being liked and trying to fit in, it's all a lot, and you're trying to find yourself while doing that."
"The only difference is that obviously, I'm doing that in the public eye."
"Definitely seeing a difference between the way people act, and the way that the press and social media have reacted to me becoming of age," she said, adding, "it can be really overwhelming."
"But it's gross and it's true and so I think it's just a very good representation of what's going on in the world and how young girls are sexualized and so I have been dealing with that but have also been dealing with that for forever."
The British actress recalled a time when the media was more fixated on how her low-cut dress made her look like "a 16-year-old" at a red carpet event.
"I thought, ‘Is this really what we're talking about? We should be talking about the incredible people that were there at the awards show, the talent that was there, and the people that we're representing."
Constantly being scrutinized on social media forced Brown to limit her online engagement to content specifically geared towards inspiring other young girls.
"You're not gonna see that part of me," she said of her personal posts.
"You get to see the things I choose to put out in the world."
"I hope if there's a 12-year-old that's told Instagram they're 18, and they've created an account, they're going on my account and they're not being exploited to the horrible world that's out there."
This isn't the first time Brown shared her experiences of being objectified by the media.
When she was 16, she wrote an Instagram post airing out her frustrations, writing:
"The last few years haven't been easy, I'll admit that. There are moments I get frustrated from the inaccuracy, inappropriate comments, sexualization, and unnecessary insults that ultimately have resulted in pain and insecurity for me."
"But not ever will I be defeated. I'll continue doing what I love and spreading the message in order to make change."
