Everybody knows millennials rule social media.

Also called Generation Y, the typical 18 to 34-year-old crowd has grown up immersed in the digital age. Millennials typically feature their lives on multiple social networks.

Social media offers a sanctuary where people openly share every intimate part of their life, one post at a time. Very little is taboo ranging from captivating to the everyday, even provocative subject-matter.

With so many details about people’s lives visible the Internet, it’s no surprise that the results of Plastic Surgery procedures are also candidly broadcast and discussed on social media.

When it comes to honest posts about Plastic Surgery millennials dominate the social space. From posting about their surgery journey—snapping selfies in the waiting room—to flaunting photos of obvious body changes, there is virtually no shame affiliated with the choice to go under the knife for the sake of beauty.

According to the American Society of Aesthetic Plastic Surgery, by and large, Plastic Surgery has seen a dramatic increase in the U.S. over the past 19 years from about 1.6 million total procedures in 1997, to nearly 13 million in 2015.

The ASAPS is an organization comprised of Plastic Surgeons certified by the American Board of Plastic Surgery who focus on Aesthetic Surgery rather than Reconstructive Surgery. The group works on providing research and education on Plastic Surgery.

ASAPS research revealed Americans spent $13.5 billion on combined surgical and non-surgical procedures in 2015. That’s a $1.5 billion increase since 2014. Non-surgical procedures refer to services such as BOTOX^® or lip fillers as in comparison with Breast Augmentation or Liposuction.

Over the past five years, the demand for cosmetic procedures have increased 39% in the U.S.

As per the ASAPS, Millennials comprise nearly 18% of all procedures performed in 2015. They may not be the age group with the most procedures performed, but it’s still a large group.

Although many patients still remain tight-lipped about their Plastic Surgery, Dr. Daniel C. Mills, the President of the ASAPS, said sharing on social media is commonplace inside Plastic Surgery Centers and hospitals.

“The number of millennials willing to do that is a lot more than any age group,” Mills said. “They’re just used to it.”

Mills expounded that for millennials, it’s not about whether or not to share a post about their Plastic Surgery, it’s which social platform to feature it on.

“They’re just much more open about it on social media,” Mills remarked. “They’ve grown up with it.”

Social media can also play a major role in urging or inspiring a person to surgically enhance their body.

With nearly 78 million followers on Instagram, Kylie Jenner, famous member of the Kardashian family, is one of social media’s reigning queens.

The 19-year-old launched a media frenzy in 2015, when she admitted to having lip injections to create her now highly sought-after lips.

There may be no proven scientific connection between Kylie’s lips and millennial Plastic Surgery, but according to the ASAPS, lip fillers, formally known as hyaluronic acids or collagen, saw a 27% increase in 2015 with more than two million procedures performed.

These filler enhancements ranked as the third most popular non-surgical procedure for millennials in 2015, following hair laser removal and BOTOX^®, according to ASAPS research.

Many millennials have their front-facing cameras ready for their not-so-secret beauty enhancements when going in to see a Plastic Surgeon, even for a basic consultation.

“Being tight-lipped about having had a Plastic Surgery procedure is a thing of the past, not only with Generation Y. We see patients in my waiting room exchanging their selfie before and afters and they are many times patients in their 40s 50s and even beyond. They see the young crowd feeling quite comfortable sharing their everything including cosmetic procedure experiences with each other on social media and so they think, Why not? I have a group of ladies who friended each other on Facebook in my waiting room and now, they even like to book appointments together and follow each other’s progress.”  — Dr. Slupchynskyj

Millennials may love to highlight their Plastic Surgery, but those social media posts come at a cost.

The average cost of a hyaluronic acid treatment in the U.S. is $591.00, according to the ASAPS. Lip fillers are temporary, meaning it’s a recurring.

ASAPS research reveals Breast Augmentation was the most popular surgical cosmetic procedure for millennials in 2015. The surgery will set a patient back an average of about $4,000.00 for silicone gel implants and $3,500.00 for saline implants.
