NAD+ Skin Health: The Science Behind Cellular Youth and How to Measure It
The beauty industry is embracing a new era of science-led skincare, with increasing attention on NADs (Nicotinamide Adenine Dinucleotide), a molecule that can help support the maintenance of healthy, youthful skin. As research into cellular repair accelerates, understanding and optimising NAD levels is emerging as a game-changer in skin vitality and ageing prevention.
What are NADs and Why They Matter for Skin
NADs (Nicotinamide Adenine Dinucleotides), the body’s natural forms of vitamin B3, are critical for energy metabolism, DNA repair, and healthy cellular function. In skin cells, NADs help repair UV damage, enable collagen production, and protect against oxidative stress, all vital for maintaining elasticity and glow.
However, NAD levels can decline with age, stress, and environmental factors, reducing the skin’s ability to regenerate and defend itself. Low NAD levels have been linked to stress, metabolic disorders, and age-related conditions, making NAD optimisation an emerging focus in both health and beauty science.
Introducing the NADMED Test – Precision Beauty from the Inside Out
Until recently, NAD testing was costly, slow, and often unreliable. Now, NADMED, a spin-out from the University of Helsinki, has developed the world’s only CE-marked blood test for accurately measuring NAD levels, offering fast, affordable, and clinically validated results.
The NADMED Test measures both NAD+ and NADH, with their ratio providing valuable insight into an individual’s cellular energy balance and overall skin health. This means decisions, such as supplement choices, can finally be guided by real biological data, not just trends.
Jari Närhi, CEO of NADMED, commented, “NAD helps power cellular repair, which can support healthy-looking skin, but until now we’ve had no easy way to measure it. With the NADMED Test, we can bring true scientific understanding to beauty and wellness, helping people see if their lifestyle and skincare are actually supporting their cells, or if they need a change.”
Beauty Consumers Are Ready for the Science
NADMED’s recent UK consumer survey* reveals a growing curiosity about NADs in the beauty and wellness space. The findings show that 40% of UK adults are aware of NAD+ supplements such as NR or NMN, and 18% of those aware are already taking them, often without knowing their actual NAD levels. Meanwhile, 14% of adults are using supplements specifically for ageing and longevity, reflecting how mainstream the pursuit of cellular youth has become.
Importantly, 76% of respondents said they would be interested in taking a blood test to understand whether their supplements or treatments are genuinely beneficial. This clear appetite for evidence-based beauty highlights a major shift in consumer behaviour; people now want measurable results, not just marketing promises.
The Future of Beauty Is Measurable
The NADMED Test represents a powerful new tool for both consumers and professionals in the beauty and wellness industries, enabling a deeper understanding of how the body supports healthy, radiant skin from within.
By integrating NAD testing to support skincare and longevity routines, individuals can personalise their approach to beauty based on science, not guesswork.
