Bryan Johnson, the entrepreneur spending over $2 million a year to reverse ageing, looks almost unrecognisable compared to a few years ago.
The tech mogul recently posted side-by-side photos of himself from 2018, 2023 and 2024 on X (formerly Twitter) to showcase his dramatic physical transformation.
"Even my Face ID is confused. I'm transitioning..." he captioned in the post.
Even from just a brief glance at the photos, Bryan's face has undeniably changed since 2018.

His face now appears slimmer, with a smooth, clear complexion, quite different from his fuller face in 2018.
The 47-year-old included a poll in his post, asking followers, "Tell me when I peaked," allowing them to choose between the three years.
Reactions were mixed, with some claiming his recent look was 'less human,' and that his appearance in 2018 'looked more human than ever.'
Specifically, a few X users pointed out that Johnson's 'chubby face' in his earlier days made him look healthier and younger.
On the other side of the internet, others think the life experiment is working really well for Johnson with comments reading: "Anyone saying you looked better before is lying" and "TRUST THE PROCESS".
Another social media user chimed in: "That is incredibly impressive, definitely a story I’m following."
Johnson’s biohacking journey is part of Project Blueprint, a program he launched early last year.
Participants pay $333 per month for a 90-day nutrition and self-experimentation program aimed at improving longevity and metabolic health.
One participant shared her positive outcomes after just 30 days, reporting major improvements in sleep quality, reduced body fat and improved overall fitness.
Under the guidance of a team of 30 doctors led by anti-ageing specialist Dr. Oliver Zolman, Johnson closely monitors his blood, heart, liver, kidneys, brain, and sexual health.
The biohacker speaks openly about his daily routine which involves taking 91 supplements, multiple meals, and an anti-ageing regimen - all before many of us have reached for our first sip of coffee.
The millionaire is openly vegan with his meals mainly made up of whole foods, with a period of intermittent fasting in the morning.
He reportedly sleeps in a cold, empty, blacked-out room on a temperature-controlled mattress.
With 'no plans to die.,' Johnson claims his biological age is about five years younger than his actual age.
Johnson was recently featured in the new documentary Don't Die: The Man Who Wants to Live Forever which is now available to watch on Netflix.
