"[Critics] are probably comparing me to season one of 'The Real Housewives of Atlanta' and then going straight to now. Where were you guys in between?" Biermann said of her evolving appearance. "You can see me every single season, and you can see how I've changed."
"I'm on Snapchat 24/7. I feel like I'm a little too open on Snapchat. If I were to do some downtime, how would that happen? People are just ignorant," she added.
Biermann specifically denied that she's had cheek implants, a nose job and a boob job. The teenager has been open about having lip injections, and said on "Hollywood Today Live" this month that Zolciak supported her decision.
"She went with me. She's known, like, forever that it was, like, a really big insecurity of mine. I've talked to her about it for years and years and years," she said.
"When I turned 18, she was kinda like, 'Okay, let's go. I don't want you going to some crazy person in Atlanta, so let's go outside to L.A. and go to the best,'" the star revealed.
Zolciak, who gets lip fillers herself, defended Biermann's choice to get injections on "Watch What Happens Live" in September.
The reality star is also mom to daughters Arianna and Kaia and sons Kroy, Kash and Kane.
