Man, 47, who spends $2million a year to have the body of an '18-year-old' reveals horrifying side-effect of procedure to make him look younger

A man who has spent an estimated $2 million a year on anti-aging has revealed the terrifying side effects of a recent procedure.

Bryan Johnson is a multimillionaire biohacker on a mission to become 18 again.

At the age of 20, Johnson, from Utah, founded Braintree, a payment gateway that lets customers pay using credit cards, debit cards, PayPal, PayPal Credit, Apple Pay, Google Pay, and Venmo.

In 2013, the payment gateway company was sold to PayPal for a whopping $800million. Johnson personally made around $300,000,000 from the sale.

The businessman, now 47, has taken on a new full-time job: himself, spending $2 million per year on his lifestyle and starting Project Blueprint.

The self-proclaimed "world's most measured human" took to his X (formerly Twitter) profile to share a candid post about his project.

"As Blueprint grew into a global movement, the scrutiny increased. Facial fat, we discovered, is pretty important for how people perceive youth. It didn’t matter how good my biomarkers were if I didn’t have face fat," he wrote.

"So, we started 'Project Baby Face,' to explore whether we can restore lost volume," Johnson added.

Here’s where things took a turn for the dramatic. Johnson selected "a first therapy: injecting a fat-derived extracellular matrix to restore volume by stimulating my body’s natural fat growth".

He decided to opt for donor fat as he didn't have enough, and this caused his face to swell to alarming proportions, blurring his vision and almost rendering him unrecognizable. 

"Immediately following the injections, my face began to blow up," he penned in the post, outlining the unexpected ordeal.

It was a severe allergic reaction that puffed up his face to the point where he was prepared for the worst during an imminent interview with Bloomberg’s Ashlee Vance.

"I called him and said, 'Hey, so that you’re not alarmed, you may not recognize me today. I think I’m ok. I hope I’m ok. If I’m not ok, are you by chance trained to perform any life-saving actions?'" he shared.

Many people were left stunned by the results and shared their reactions. "Our mission statement is to do literally everything the complete opposite of this guy," one person wrote.

"I really appreciate this guy’s efforts, but did he really just say he injected someone else’s fat in his face for purely cosmetic reasons?" another questioned.

Fortunately for Johnson, his facial features deflated back to normal after a nail-biting seven days.

Unfazed, he and his team went back to the drawing board and started "reformulating plans for our next attempt".

"Building a product is one thing; being the product is a whole different thing," he concluded in the post.
