When asked if she had any work done to her face, Marie, who wed Mike Shay last year, revealed she had Botox, and claimed she did so in order to avoid getting wrinkles. On Twitter, she explained how often she has it done.

On Wednesday, after a curious fan asked Marie if she got Botox "quarterly," Marie said, "Yea like every 3-4 mos."

Marie hasn't had any other work done, and recently denied a breast augmentation after showing off her chest in a low cut gown on Watch What Happens Live.

Also on Twitter, after being confronted with allegations that Botox wasn't something used for preventative maintenance, Schroeder explained, "Then clearly u haven't done ur research."

In an interview with Vogue last year, New York City's Patricia Wexler, M.D. explained the benefits of using Botox.

“[Botox] can certainly stop the clock, and the frequency and dose will be lower if you begin [using it] when you begin seeing evidence of damage,” she explained. However, it shouldn't started before there are signs of wrinkles.

“If you don’t see any lines when your face is at rest, then doing Botox is not preventative. It’s presumptive,” she added.

The second half of the Vanderpump Rules reunion airs on Monday at 8 p.m. on Bravo.
