Viavi was recently featured in US Weekly as part of an article exploring the growing popularity of celebrity-backed longevity treatments, from red light therapy and cold plunges to NAD+ drips, stem cell injections and peptide shots.
The feature looks at a question many people are now asking: which wellness trends are actually supported by science, and which ones are being driven more by hype, celebrity endorsement and marketing?
As part of the article, Dr Sabine Donnai, founder of Viavi, shared expert insight on peptide injections, their current limitations and why the strongest longevity interventions often come back to the fundamentals: metabolic health, cardiovascular risk, sleep, muscle strength, inflammation, diet and exercise.

Key Takeaways
- Viavi was featured as an expert voice in a wider Us Weekly article about popular celebrity longevity treatments.
- The article explores the difference between wellness trends with a growing evidence base and treatments where the marketing may be moving faster than the science.
- Dr Sabine Donnai commented specifically on peptide injections and the importance of understanding their current regulatory and clinical limitations.
- The feature highlights a broader issue in longevity: not every treatment promoted as “anti-ageing” is proven to extend lifespan or improve long-term health.
- Viavi’s perspective reinforces the importance of focusing on evidence, safety, medical oversight and the foundations of healthy longevity.
“They are being overused and over-promised, and the product quality is a massive concern to medical professionals.”
-Dr. Sabine Donnai, Founder & CEO of Viavi
Why This Feature Matters
The Us Weekly article reflects a wider shift in how people are thinking about longevity. More people are interested in taking control of their future health, improving performance and reducing the risks associated with ageing. That is a positive change.
The challenge is that the wellness market is crowded with treatments, devices and protocols that can be difficult to assess without medical context. Some approaches, such as red light therapy, have a growing clinical evidence base in areas such as skin health, recovery and inflammation. Others, including some injectable treatments marketed for anti-ageing, remain far less established.
For individuals trying to make informed decisions, this creates an important question: how do you know what is worth exploring?
The answer is not simply to follow what celebrities are doing. It is to understand your own health, your risk factors, your symptoms, your goals and the quality of the evidence behind any proposed intervention.
