"I still do Juvederm for my lips. He's the best, and he's super natural about it. I was going to somebody before, and it was just looking crazy. I would recommend that anyone who gets it done go for a filler that lasts only two to four months. It's annoying to keep going back, but you have the option of stopping it." Kim Kardashian's 18-year-old half-sister KYLIE JENNER praises her Beverly Hills plastic surgeon, Dr. Simon Ourian, for her full lips. The reality TV regular owned up to having lip fillers in May (15) following speculation online about her new look.
