"So I had my lips redone at California Cosmetics, and they're amazing," Zolciak said in a video. "I'm incredibly bruised, honestly, underneath the makeup."

"The technique is amazing, and it's basically pain-free. They're a little bruised, but they look really good," she continued.

"Bruised and swollen," she captioned a pic of her lips, "but love @california_cosmetics."

The mother of six continued to show off her treatments on Thursday, snapchatting herself with an IV in her arm.

"I have super low iron, I kind of always have, so I'm getting an iron IV," she explained in a video. "It's super important, guys, to maintain your iron levels."
