Jill Zarin's latest battle isn't with any of her costars -- this one is against Father Time.

"I started doing a liquid facelift about two years ago, and I do it every five or six months," Zarin explains. "It's very subtle and you shouldn't really notice it, but it sort of wards off the sagging and the aging process."

"The Real Housewives of New York City" airs Thursday at 10 p.m. (EST) on Bravo.
