Biomarkers Are Becoming the Language of Longevity

Biomarkers are quietly becoming the new language of longevity, and glycans may be among the most actionable indicators for resilience and healthy aging.

During a recent keynote, Prof. Gordan Lauc emphasized a fundamental reality: there is no “standard human.” Yet much of modern medicine—and many wellness solutions—are still built around population averages.

Only a small fraction of longevity is determined by genetics. Most of our long-term health trajectory is shaped by lifestyle, daily behaviors, and environment.

This is exactly where glycans come in.

Glycans—complex sugar structures attached to many proteins in the body—sit at the intersection between genes and lifestyle, translating daily behaviors into biological signals.

Why Glycans Matter for Consumers

Unlike our genome, which remains fixed throughout life, glycan patterns—particularly those attached to immunoglobulin G (IgG)—change over time.

These patterns shift in response to:

  • aging
  • inflammation
  • stress
  • disease
  • lifestyle factors

Importantly, these biological changes often occur years before clinical symptoms appear.

This makes glycans a powerful biomarker of:

  • biological age
  • systemic inflammation
  • what Prof. Lauc described as “personal resilience” or intrinsic capacity.

For the beauty and wellness industry, that idea is particularly compelling. Resilience is not just an abstract wellness concept; it is something that may increasingly be measured and tracked.

Key Insights from Prof. Lauc’s Keynote

Several insights from Prof. Lauc’s presentation stood out, especially when viewed through an executive lens for beauty, wellness, and longevity brands.

Medicine today is still largely trial and error.
For some widely used drugs, as many as 25 people may be treated for only one person to benefit. Precision medicine remains the goal.

Most disease risk is not genetic.
For many complex diseases, only around 30% of risk is heritable. The majority is shaped by lifestyle and environmental exposures.

Glycosylation is not the same as glycation.
Glycation is random sugar damage caused by excess glucose (as seen in HbA1c). Glycosylation, by contrast, is a highly regulated biological system that enables complex cellular communication.

IgG glycans influence immune behavior.
These structures can affect how antibodies interact with the immune system—whether they activate inflammatory responses, collaborate with T cells, or maintain immune tolerance.

Glycan aging changes significantly across the lifespan.
Women tend to remain relatively protected until perimenopause, after which glycan aging accelerates rapidly and begins to align with male patterns.

Biological age gaps can be significant.
On average, glycan age may differ from chronological age by around nine years, with some individuals appearing up to twenty years older or younger at the immunoglobulin level.

Higher glycan age correlates with higher mortality risk.
This relationship appears particularly strong in people in their forties and fifties.

Sitting in a room filled with clinicians and scientists, the business question quickly becomes clear:

How do we translate this emerging glycan layer of biology into meaningful value for consumers purchasing skincare, supplements, wellness programs, or longevity services?

From Diagnostics to Desirability: What This Means for Brands

Glycan-based tests are already available in thousands of clinics worldwide. With only a small blood sample, laboratories can analyze glycan structures and estimate a person’s glycan age.

These tests can reveal unhealthy trajectories years—sometimes a decade—before disease diagnosis, reflecting cumulative lifestyle effects on systemic inflammation and resilience.

For consumer-facing brands, this opens several strategic opportunities.

1. From Generic Advice to Measurable Personalization

Glycans change with lifestyle and correlate with markers of unhealthy living.

This creates an opportunity to move beyond general wellness messaging and toward measurable personalization.

A typical model could include:

  • measuring glycan age at baseline
  • implementing a targeted protocol (nutrition, supplements, sleep optimization, stress reduction, skin or gut support)
  • re-testing after a defined period

The result is personalization that can be demonstrated biologically, not just promised.

2. Positioning Resilience as a Core Brand Promise

IgG glycans behave more like a resilience biomarker than a disease-specific marker.

They reflect overall health and intrinsic capacity across multiple conditions.

As consumer behavior shifts away from quick fixes toward long-term performance and longevity, brands have an opportunity to reposition around measurable resilience.

Instead of promising cosmetic transformation alone, the narrative becomes:

Supporting the biology that keeps people resilient, functional, and adaptive through midlife and beyond.

Membership models, retreats, and subscription wellness programs could integrate resilience tracking as part of their value proposition.

3. Innovation for Women in Midlife and Menopause

One of the most compelling data points presented was the pattern of glycan aging in women.

Glycan profiles tend to remain relatively youthful until perimenopause, after which biological aging accelerates significantly.

For brands serving women aged 40 and above, this insight may shape both product development and program design.

Opportunities include:

  • menopause-focused lines positioned around immune and inflammatory resilience, not only hormone support
  • longitudinal programs lasting 12 to 24 months, where glycan age becomes a measurable outcome

4. New Metrics for Loyalty and Community Programs

Glycan age is largely independent from other biological clocks such as epigenetic aging markers or traditional blood-based mortality scores.

That means it introduces new information, not just another version of the same metric.

For brands building premium ecosystems, this creates interesting possibilities:

  • high-touch coaching or concierge longevity programs
  • premium communities where members track biological and visible improvements over time

Imagine a loyalty journey where customers see improvements in:

  • skin quality
  • energy levels
  • sleep patterns

while also watching their glycan age trend younger than their chronological age.

Practical Takeaways for Beauty, Wellness, and Longevity Leaders

For leaders building consumer brands in this space, a few practical steps stand out.

First, explore partnerships with clinics or laboratories offering glycan-age testing. Pilot programs around resilience tracking can help translate complex biology into meaningful consumer experiences.

Second, design interventions with sufficient duration and intensity to realistically influence systemic inflammation and glycan patterns. Multi-month, multi-modal programs are far more likely to produce measurable change than single-product solutions.

Third, for offerings targeting midlife women, align educational content and product narratives with the biology of accelerated glycan aging during perimenopause.

Finally, ensure scientific communication is accurate. Teams and customers should understand the distinction between glycation (random damage) and glycosylation (regulated biological signaling).

The Bigger Picture: Resilience as a Measurable Strategy

What stood out most from Prof. Lauc’s presentation is that resilience is not an abstract concept.

It is measurable, adaptable, and strongly influenced by how we live—often long before illness appears.

For the beauty, wellness, and longevity industries, the next challenge is clear.

How do we design offerings that respect this biological complexity while making it simple, actionable, and inspiring enough for people to engage with?

Because when resilience becomes visible and measurable, it has the potential to reshape how consumers think about health, aging, and longevity altogether.
