After facing criticism over remarks suggesting Australians tend to have older-looking skin because of sun exposure, Bryan Johnson’s Australian girlfriend has shared her own claims about turning back the clock on her complexion.
Kate Tolo, 30, posted a detailed explanation on X, saying her skin biomarkers now align with those of a 21-year-old and outlining the steps she says helped reduce her skin age by nearly a decade.
Her comments follow the couple’s recent trip to Australia to visit Tolo’s parents, during which Johnson, 48, criticised the intensity of the country’s sun. The millionaire biohacker said that after just one week Down Under, he believed his skin had shown measurable signs of aging.
“Australians have older-looking skin,” Johnson wrote on X, formerly known as Twitter. “The Australian sun increased my skin aging by five per cent (via UV damage and spots).”
Johnson also cited a 2017 study from Monash University, which suggested Australian women appeared to age 10 to 20 years faster than women in the United States.
Tolo now appears to be addressing the issue from her own perspective. In her post, she said she initially achieved her youthful appearance without Botox or filler, though she noted she has since used cosmetic injectables for facial balancing.
“Before I dive in, it’s important to note that facial aging is made up of MANY different parts,” she wrote.
Tolo, who has been in a relationship with Johnson for nearly five years, went on to provide a comprehensive breakdown of the changes she says contributed to her skin transformation.
After being roasted for claiming Australians have older-looking skin because of the sun, Bryan Johnson’s Aussie girlfriend has declared how she has reversed her skin age by a decade
Kate Tolo, 30, shared a lengthy post claiming she has the skin biomarkers of a 21-year-old, delving into what she did to reverse her skin age
She started by stating the obvious – that aging heavily impacts the body, listing bone structure, collagen, hydration, elasticity, fat and placement of tissue (gravity).
She started by advising people to treat any major conditions that could be affecting the skin – such as acne – and then add basic interventions like sun protection and getting a face scan before targeting specific problems.
Tolo added she is not saying she looks 21 years old but according to the markers, that’s the age of her skin.
‘It’s also worth noting that five years ago, I was eating McDonald’s daily and did not do anything specific for my skin,’ she added.
She claimed that according to a face measurement scan she received, at age 27, her skin was age 26 and now at age 30, her skin is age 21.
‘This means that in three years, instead of accumulating three years of skin age, I reversed my skin-age by five years,’ the biohacker wrote.
Tolo explained that the device uses multi-spectral imaging, which consists of polarized and UV lighting to assess surface and subsurface skin features and that she was regularly getting scans to assess the changes.
She said in addition to sun protection, getting more sleep, eating healthily and undergoing red light therapy, she has also microdosed Accutane as well as using a hyaluronic acid supplement, vitamin C supplement, omega-3 supplement, copper supplement and vitamin D supplement.

Do extreme anti-aging routines genuinely benefit us, or are we being sold unrealistic beauty standards?
She also listed collagen, extra virgin olive oil, omega-3, advanced antioxidants as well as the Blueprint Longevity Mix, Essential capsules, serum, moisturizer and cleanser as her non-negotiables.
According to Rene Torres, an esthetician, functional nutritionist and wellness director of OSMOSIS, the foundational practices used by Tolo can impact both skin health and overall wellness – but there are other options for people to partake more cost-effectively.
‘It’s important to remember that aging well does not require an extensive protocol built on aggressive formulas, multiple devices, excessive supplements, or a long list of procedures that come with significant financial cost,’ she told the Daily Mail.
The esthetician said that while it’s important to be sun smart, avoiding sunlight entirely for cosmetic reasons may have unintended consequences.
‘The goal is not to fear the sun, but to respect and work with it, embracing healthy, balanced exposure that supports the body’s natural processes while avoiding excess that can contribute to long-term skin damage,’ she explained.
Torres added that appropriate sun exposure supports vitamin D production, healthy sleep and circadian rhythm balance, cardiovascular function and skin health, while complete avoidance can negatively impact aging bodies.
In the post to X, Tolo said she did not use initially Botox or filler to achieve her youthful visage but has since used it for facial balancing
Instead, Torres recommended a holistic approach that recognizes the body functions as an interconnected system.
‘Rather than continually adding more treatments, devices, or supplements, the focus should be on identifying what the body truly needs and supporting its natural ability to maintain balance, repair, and healthy aging,’ she suggested.
‘If someone enjoys these treatments and feels they are necessary to achieve their personal goals, that’s their choice. However, many of these interventions are not essential, they do not work equally well for everyone, and many carry the potential for long-term consequences.’
Johnson, a US entrepreneur and investor, is best known for his controversial Blueprint program and his attempts to biologically reverse the aging process.
The California tech entrepreneur has attracted global attention for his controversial quest to extend his lifespan, reportedly spending about $2 million a year on treatments, testing and lifestyle interventions aimed at slowing and even reversing biological aging.
Johnson and Tolo, who have an 18-year age gap, met when Tolo joined Johnson’s Blueprint anti-aging venture as chief marketing officer.
