Younger sister Kylie Jenner faced years of scrutiny after continually denying she had not had lip fillers. After finally admitting to the cosmetic enhancements, Kendall received some of the backlash too, with many claiming she had also gotten her lips filled. The sisters still continue to claim it is "overlining" their lips with lip liner that is the secret to their fullness.
Kendall, who has always been regarded as the "natural" Kardashian sister, is the face of Estée Lauder, ProActiv's newest ambassador and the leading figure in the new generation of supermodels, making her a target for those who believe she's had plastic surgery.
While reviewing Jenner's beauty transformation, it's not hard to see why some are convinced. However, it could be a case of late blooming for the star, who's been in the public eye since she was just a tween.
Whether the Victoria's Secret model has or hasn't gone under the knife, which she has continuously denied over the years, it's ultimately her decision.
Take a look at Kendall's before and after transformation...
2009
Kendall Jenner at the Teen Choice Awards
At just 13-years-of age, Kendall was already strutting the red carpet like a pro. Despite still sporting her signature straight locks, it's easy to see why fans believe the model may have gotten a nose job, as her face looks considerably different. However, I'm sure all of us have an image of ourselves pre-puberty that look somewhat nothing like us.
2010
Kendall Jenner arrives at the Los Angeles Premiere of Burlesque
In 2010, Kendall started to wear makeup and began styling her hair in ways fans had never seen before. At age 14, the daughter of Kris Jenner looks many years her senior. What stands out most is the young TV stars smile. Her upper lip seems noticeably thinner than it is today.
2011
Kendall Jenner attends the Grand Opening of the Kardashian Khaos store
Between 2010-2011, Kendall doesn't appear to change in appearance too much. Despite fans claiming they start to notice a difference in the Keeping Up With The Kardashian stars eyes, it could be down to the young models use of fake eyelashes.
2012
Kendall Jenner attends the Seventeen Magazine poolside party
With Kendall's modelling career beginning to pick up, the star begins wearing her hair in a style that will become somewhat of a staple for her. Sleeked back in a bun, Jenner really starts to look older and more mature in her features.
It's this year that her lips begin to appear noticeably fuller, especially her top one. Her eyes appear to have become more cat-eye, but in this image Kendall is wearing a pair of full winged eyelashes that could account for the enhanced look.
2013
Kendall Jenner attends the iHeartRadio Music Festival
In 2013, Kendall changed up her appearance by lightening her hair colour with streaks. Her lips continue to look full and rounded, while her nose appears to have thinned out compared to her 2011 and 2012 shots.
Kendall is, however, wearing a heavier makeup look than before, which could account for the star's 'smoothed over' features.
2014
Kendall Jenner arrives at the 2014 MuchMusic Video Awards
By 2014, Jenner is just about everywhere. KUWTK would reach one of it's peaks, with over three million viewers tuning in to this years premiere episode. This year, it's not hard to see the Kardashian influence on Kendall, with the reality star sporting a contoured face, heavy lashes and much more makeup than fans were used to seeing on the natural beauty's face.
However, her nose appears the same and her lips are still relatively thin. Looking close up on the photo below, it seems Jenner has drawn a nude liner above her lip line, attempting to give the appearance of a fuller lip.
2015
Kendall Jenner arrives at the American Music Awards
It's hard to believe that Kendall is just 19-years-old here. Sporting bangs for the first time, the model appears much older than her years.
Jenner's lips appear fully defined, much more so than normal, and her nose appears narrower from bridge to top.
However, considering the drastic change in hair style, Jenner's thinner nose could be a result of illusion.
2016
Kendall Jenner attends the Magnum Doubles Party at the annual 69th Cannes Film Festival
In 2016, Jenner's fans would continually criticise the star for going "too far" with her lip injections. However, the model continually denied accusations she had cosmetic enhancements, and maintained it was clever uses of makeup behind her plump lips.
2016 was also the year fans began to question whether the star had done something to her eyes and forehead, as her eyebrows began to look higher up on her face than in previous years.
The star does start sporting much fuller and defined eyebrows, which became a huge Instagram trend thanks to the likes of models Cara Delevingne and Bambi Northwood Blyth. This left many believing that the thickened lines of her brows created an illusion equal to that of surgery.
It's also important to note Kendall's lack of fake eyelashes here, which could also attribute to her eyebrows appearing further away from her face.
2017
Kendall Jenner attends the Chopard SPACE Party
By 2017, Kendall's lips appear fuller than ever, with her pout being continually compared to that of her sister Kylie Jenner. Despite being clearly defined in the picture below by a darker liner than gloss, there's no denying Jenner's lips became significantly larger since 2011.
With the contouring trend in full swing by 2017 too, it's easy to see Jenner's employed the technique down the centre of her nose to give off a thinner and elongated feature.
Jenner has also employed a much more natural eyelash look since 2015, making her eyes appear fuller and less cat-eyed than previous years.
2018
Kendall Jenner attends the Vanity Fair Oscar Party
In 2018, Kendall was named the World's Highest Paid Model by Forbes. The 23-year-old banked $22.5 million in the twelve months prior to June 2018 to top the year's ranking.
Jenner appears to keep her lips as plump as the previous year, if not more so. Her nose appears significantly smoother than years previous too. Plastic surgeon Miles Barry told the Daily Mail: "The bridge of her nose...could certainly have been smoothed surgically. The tip could well be smaller and rather more refined, again pointing to possible surgery. An alternative could be that she has had the much less invasive procedure of filler injected and this has smoothed out the bridge."
Again, Jenner opts for a much more natural eyelash look than her younger self.
2019
Kendall Jenner attends a basketball game between the Los Angeles Clippers and the Philadelphia 76ers at Staples Centre
By 2019, Jenner's look keeps her plumped upper lip and natural lashes.
Jenner's beauty transformation remains up for debate, but a final word on the matter the star debunked cosmetic surgery theories via her app in 2017.
She explained that Kylie's makeup techniques were responsible for her altered appearance after a Facebook Live event they did together.
“All of a sudden, photos of us came out with headlines like, ‘OMG Kendall got her lips done and got full facial reconstruction — look at her cheekbones, look at her nose!’ I was like, this is CRAZY. I didn’t even address it at the time. Because if I address it, people are going to be like ‘Oh, so she’s defending herself — she must be guilty,’” Jenner wrote.
Her sister, Kylie Jenner, had previously jokingly accepted responsibility for sparking the rumours after doing her makeup. “You guys, Kendall let me overline her lip today with lip liner and everyone thinks she got lip injections. I’m sorry, Kendall,” she said on Snapchat.
