Plastic surgeons explain the changes to Khloe Kardashian's nose, chin, and cheeks

• After Khloe Kardashian shared a Twitter video, people began to comment on the appearance of her face. Her chin appeared pointier and her nose thinner, some said.
• In May, the internet also chimed in about Kardashian's potential cosmetic procedures after she shared an Instagram selfie.
• According to plastic surgeons, Kardashian's face changes are likely the result of nose surgery, fillers, weight loss, and video and photo filters.

The internet is analyzing Khloe Kardashian's face again after she shared a Twitter video where her chin appeared to be pointier than previous images of the reality star.

On November 16, Kardashian posted a video thanking fans for voting and helping her win a People's Choice Award.

Soon after Twitter users responded, bringing up her nose and chin. Some attributed Kardashian's look to high-tech video filters, while others said it was the result of more plastic surgery.

"You look so incredibly different and unlike yourself. I don't even recognize your face anymore," one user wrote.

According to board certified plastic surgeon Dr. Hootan Zandifar, it appears a mixture of surgery, weight loss, and photo filters helped Kardashian achieve her appearance.

Zandifar attributed Kardashian's chin changes to fillers, which can "increase the projection" of the feature and make it appear more defined, as well as weight loss. Kardashian recently spoke about her 60-pound weight loss on a livestream for her sister Kourtney Kardashian's brand Poosh.

Additionally, Zandifar said the tip of her nose looks thinner than in previous photos, which to him signals a rhinoplasty, or nose job.

"You can achieve some of these effects with appropriate makeup and photo filters, but the amount of decrease in width of the tip suggests to me a rhinoplasty procedure," he told Insider.

The new changes come 6 months after Kardashian revealed changes to her nose, cheeks, and chin

This isn't the first time people have brought up Kardashian's apparent face changes.

In late May, Kardashian posted Instagram selfies with marked facial differences from previous ones she shared. Her nose appeared more narrow, her cheekbones sat higher on her face, and her jawline looked more defined.

According to Dr. Arash Moradzadeh, a plastic surgeon based in Beverly Hills, California, it's difficult to pinpoint the exact procedures Kardashian underwent due to the widespread use of face filters on Kardashian's social media.

First, Moradzadeh said Kardashian may have had another rhinoplasty, or nose job, since her nose appears thinner than in previous photos.

He also said it looks like she had buccal fat removed from her face, which is a type of fat in a person's cheeks. When these fat "pads" are removed, it can create a more sculpted look in the hollow part of the cheek, according to the American Society of Plastic Surgeons.

Last, Moradzadeh said Kardashian's defined jawline could be due to filler injections.

"There's definitely modifications to filler in her jaw line, cheek, bone, chin area, and lips," he said. "And then after that it's contacts and lashes and makeup and Photoshop and filters. Those are the things that I noticed when I look at the photograph."

Kardashian hasn't explicitly stated the procedures she'd had or named specific editing software, but she has alluded to both.

After a fan commented on her May selfie, "Why do you look so different in all your photos?" Kardashian responded, "From my weekly face transplant, clearly."
