Bryan Johnson spends $2M a year to grow younger: we compared his longevity protocol to the price of a UPF 80 T-shirt
Bryan Johnson invests $2M a year to gain a few years. On his list of protocols: UV protection. The most cost-effective longevity routine does not cost a fortune.
Bryan Johnson spends roughly two million dollars a year to slow his ageing. Supplements, sensors, examinations, medical teams: his "Blueprint" protocol has become the global symbol of the longevity movement. But looking closely at the list, one line stands out for its simplicity — and its trivial price: protection against UV. We compared.
The longevity market, a new gold rush
Longevity is no longer a niche subject. The global market for "anti-ageing" and "healthspan" products and services is estimated at several tens of billions of dollars, with projections seeing it climb towards 70 to 80 billion by the middle of the decade.
Behind the figures lies a promise: living longer in good health. And a whole industry of supplements, devices and protocols competing for the attention — and the wallets — of consumers ready to invest heavily in their health capital.
Bryan Johnson, Huberman: what they really do
The flagship figures of the movement — Bryan Johnson and his Blueprint protocol, the neuroscientist Andrew Huberman and his widely followed recommendations — share a common foundation, often less spectacular than the headlines:
- Sleep treated as an absolute priority, measured, optimised.
- Diet kept in check, regular exercise, cold exposure.
- A battery of supplements — whose real cost-effectiveness is debated within the scientific community.
- And, almost always, systematic sun protection.
This last point often goes unnoticed in the media coverage, focused on exotic molecules. Yet ask any dermatologist what the best-documented anti-ageing gesture is: it will be neither a supplement nor a cold bath. It will be protection against UV.
Hypersanté Paris 2026: longevity arrives in France
The movement, long very American, is settling in France. The Hypersanté Paris summit, held in early 2026, brought together the French-speaking biohacking and longevity community — proof that the subject is leaving the Californian podcasts to enter the French health debate.
It is a good occasion to ask a simple question: in all this arsenal, what is genuinely cost-effective?
The opportunity calculation: exotic molecules vs daily UPF 80
Let us compare honestly, reasoning like an investor — which Bryan Johnson, a former entrepreneur, does himself.
On one side: costly supplements, demanding protocols, devices costing several thousand euros, and a level of scientific evidence ranging from "promising" to "highly contested". On the other: a UV protective garment worn every day, whose effect on the skin is, by contrast, perfectly established.
The most cost-effective longevity routine on the market does not come in a capsule. It is pulled on in the morning and requires no renewal during the day.
A T-shirt certified UPF 80 blocks 98.75% of UV radiation. Set against its price and the years it covers, the cost of this protection bears no comparison with that of a stack of supplements — for a skin benefit that is, for its part, undisputed. It is the most favourable "scientific evidence per euro spent" ratio in the entire longevity market.
The science behind it: 80% of photoageing comes from the sun
Why is UV protection the best-founded anti-ageing gesture? Because the share of skin ageing attributable to the sun is massive.
The reference work — including a famous twin study published in the Journal of the American Academy of Dermatology — converges on the same order of magnitude: around 80% of the visible ageing of the skin is due to UV exposure, and not to the passing of time. Wrinkles, spots, loss of elasticity, texture: most of what we call "ageing" on the face and the hands is photoageing — so, to a large extent, avoidable.
In other words: you can pile up molecules to act at the margins on the 20% linked to biological time — or act first, simply and at almost no cost, on the 80% linked to the sun. It is the same reasoning we set out in Longevity skincare: UPF 80 is the real anti-ageing routine.
Bryan Johnson has understood it: in his two-million-dollar protocol, UV protection is one of the cheapest lines — and one of the best justified. The good news is that this particular line is one everyone can afford. It does not cost a fortune. It is worn.
