Longevity Science Is Redefining Personal Care Ingredient Development

Ingredient development in personal care is pivoting from anti-ageing and reversal toward biological maintenance, preventative support and long-term functionality, according to a new report from RX Global, the organiser of in-cosmetics Global.

Titled The Science Shaping Longevity in Personal Care 2026, the report draws on industry intelligence, expert commentary and recent ingredient innovation examples to examine how longevity science is changing the way beauty products are researched, formulated and evaluated.

RX Global developed the report with Euromonitor International, and Coachchem sponsored it. Contributors include Shiseido, DECIEM, BASF, Symrise and DSM-Firmenich — a lineup that spans leading beauty brands, ingredient suppliers and scientific experts.

The report covers skin care, hair care, fragrance, nutricosmetics and body care, offering a cross-category view of emerging developments and commercial opportunities.

What does the shift away from anti-ageing actually mean?

Euromonitor's Ina Dawer, Global Insight Manager: Ingredients, frames the change in direct terms.

"The strongest signal in longevity is the move away from anti-ageing and reversal, and toward longevity as functional health span," Dawer said.

"In beauty, this is showing up through skin span and increasingly hair health span, where the focus is maintaining resilience, recovery and barrier integrity over time," she added.

Her third point may carry the most weight for formulators: ceramides, peptides, antioxidants and microbiome-supporting actives are no longer niche hero ingredients. According to Dawer, "they are becoming formulation baselines across skin care and hair care. Longevity built on maintenance and resilience is proving far more durable than transformation-led marketing claims."

That framing matters for evidence standards too. If maintenance replaces transformation as the marketing story, claims will rest on sustained barrier function and resilience data rather than before-and-after reversal imagery.

Which technologies does the report flag?

Biotechnology sits at the centre of the analysis. Advances in precision fermentation and microbiome science are creating new formulation possibilities for personal care.

The report also examines:

• PDRN (polydeoxyribonucleotide) as an emerging ingredient technology
• Exosome-inspired delivery systems
• Biomarker analysis and clinical testing as tools to demonstrate ingredient performance

The emphasis on biomarker analysis signals a tighter link between ingredient claims and measurable biological endpoints — a shift that aligns personal care evaluation more closely with clinical-testing conventions.

How are consumer expectations steering innovation?

Consumer expectations are shaping direction as longevity connects more closely to everyday health and wellbeing. Nutricosmetics, functional ingredients and convenient delivery formats are gaining importance in supporting long-term wellness routines, the report finds.

Neuroscience is opening a parallel track in fragrance. The report highlights new possibilities from understanding the relationship between sensory experiences and emotional wellbeing — a pairing that positions scent within the wellbeing proposition rather than pure aesthetics.

Where is longevity spreading next?

Longevity thinking is gaining traction beyond facial skin care into scalp health, hair care and body care, according to the report.

One factor stands out for its near-term commercial relevance: the growing use of GLP-1 medications is creating new considerations for personal care innovation. As more consumers take these drugs, formulation needs around body care and related categories are likely to evolve.

The report illustrates its analysis with ingredient technologies and formulation concepts from across the global industry, showing how advances in science translate into practical applications.

With contributors spanning Shiseido to DSM-Firmenich and a scope reaching from fermentation to fragrance neuroscience, the report positions longevity not as a claim trend but as a reformulation of what baseline ingredients must do — and how their performance gets proven.
