Kim Kardashian's sister insists she has never undergone cosmetic surgery, but she has had injections in her face. However, she feels the procedure messed up her looks, and she is not sure she would try it again.

"Everyone says I've had my nose done and I swear I haven't," she said on her show Kocktails With Khloe. "I don't know if it's Botox or filler, I did one of them and my whole face went numb and I could not make (an expression). I had to dissolve everything... I looked crazy and I still think the effects are, like, in there."

Khloe's experience became even worse when estranged husband Lamar Odom fell into a coma following a drug overdose in a Nevada brothel last October (15).

"I was so stressed out that the doctor was like, 'I think it's just that too much was happening to your real emotions'," she continued. "And my face was so f**ked. I had to go and get this whole thing, like, dissolved. It was a bummer because now I'm afraid to do it again, but I swear, I think things are still in my face."

Despite her bad experience, Khloe has not completely sworn off plastic surgery and cosmetic enhancements.

"There's this misconception that I'm not into plastic surgery, but I'm into it and I don't care if you have it," she previously told Cosmopolitan magazine.

Insisting it's "almost like makeup", Khloe continued, "We're all putting on a f**king mask basically every day anyway. When you dye your hair, you're changing who you are, and I don't think there's anything wrong with that."

Khloe is not the only member of the family who has tried fillers - the reality star's younger sister, Kylie Jenner, admitted to having lip injections last year (15).

"I have temporary lip fillers," she said. "It's just an insecurity of mine and it's what I wanted to do."
