Kylie Jenner has been "wise" about her choice of cosmetic treatments, according to plastic surgeon Doctor Simon Ourian.
The famous family's trusty dermatologist believes the 18-year-old star, who has been having lip fillers since the age of 17, is very sensible when she undergoes treatments.
Speaking on Khloé Kardashian's website khloewithak.com about her half-sister's transformation, he said: "Kylie has become very wise in what she wants to have done. She has been going through an amazing metamorphosis over the past couple of years."
And Kylie isn't the only member of the family who is very particular about her surgery as Kim Kardashian West, 35, has a similar view.
He said: "Kim is very detail-oriented and knows exactly what she wants and needs, so when I work on her, it is like working with a colleague and I really enjoy it."
Meanwhile, the 'Kocktails with Khloé' host sought help from Simon when another surgeon "f***ed up" her fillers a few years ago.
She said: "My cosmetic dermatologist, Dr. Simon Ourian, is the truth!!! My sisters and I have been going to him for years for laser treatments and skin care at Epione, and he has seriously made my skin perfect. He even removed my tramp stamp! A while ago, I made a comment about how some doctor f***ed up my face with fillers and I need the world to know that it wasn't Dr. Ourian, LOL!!! After that experience, I went back to Dr. Ourian and he totally dissolved the fillers and fixed me. He's the BEST and you need to get to know him. (sic)"
