It was suggested Kylie, 17, might have had cosmetic enchantments after she sported plump lips, and she also sparked rumours of a boob job last year.
But speaking to Cosmopolitan, the reality TV star put it down to growing up.
She said: "You guys have watched me grow up since I was nine. My face is going to get different.
"Now, I know how to do my make-up, contour and everything. I'm not against surgery. I'd never say no, but I don't desire it right now."
The Keeping Up With The Kardashians star admitted to struggling sometimes growing up in the public eye, especially with having such beautiful older sisters.
She said: "When I was like 10, 11, 12 I had a really hard time with the media.
"During your adolescence, girls deal with their peers at school, then they go home and they don't have to deal with it (there).
"It was a lot more haters to deal with. Especially since I was younger and my sisters were so beautiful and had it all together."
Despite this, Kylie insists she wouldn't change her life and likes things just the way the are.
She added: "I can have my moments and say I don't want this life anymore, but I wouldn't trade it for the world. The good is definitely worth the bad."
