Natori Multibiome HD | Postbiotic Moisture Retention Beyond Beta Glucan

September 14, 2026

Barrier hydration is now the benchmark the personal care market judges skincare by. Consumers no longer separate moisturisation from skin health, and formulators are expected to deliver both in a single system. Within that shift, polysaccharide humectants such as beta glucan have become the reference point every new moisturising active is measured against.

Natori Multibiome HD enters that comparison from a different direction. Rather than relying on one polysaccharide to hold water at the surface, it is a postbiotic complex built from a broad set of fermented materials, enriched with multiple postbiotic types and Lactobacillus strains selected to reflect the skin microbiome profile of healthy young skin. In controlled testing, Natori Multibiome HD retained moisture in the skin more effectively than a beta glucan reference, pointing to sustained hydration rather than a brief surface effect.

Why Moisture Retention Matters More Than Initial Uptake

Many hydrating actives perform well in the first minutes after application. Water is drawn to the stratum corneum, instrumental readings rise, and the claim is made. The harder question is what the measurement looks like hours later, once the initial humectant load has equilibrated with the environment.

Moisture retention is the more demanding endpoint because it depends on the skin holding water rather than the formula simply supplying it. That requires an intact barrier, functional lipid organisation, and a stable surface environment. Natori Multibiome HD was evaluated against a beta glucan reference on exactly this basis, and demonstrated superior retention over the measurement window. The distinction matters for product positioning: an active that supports retention supports an all day hydration claim, while an active that only drives initial uptake does not.

A Broad Postbiotic Complex, Not a Single Strain

Postbiotic actives vary widely in how they are constructed. Some are the ferment filtrate of a single organism, which limits the range of metabolites present. Natori Multibiome HD takes the opposite approach: it is assembled from a broad set of fermented materials so that the finished active carries a wide spectrum of postbiotic components rather than the narrow output of one fermentation.

That breadth is deliberate. Skin does not respond to a single metabolite in isolation. The complex is further enriched with multiple Lactobacillus strains chosen to reflect the microbial profile associated with healthy young skin, giving the active a compositional logic rather than an arbitrary blend. For brands building a microbiome story, this composition is a substantive point of difference rather than a label claim.

Working Through the Microbiome Rather Than Around It

Conventional humectants act physically. They bind water, they slow its loss, and their effect ends when they are washed away. A postbiotic complex works on a different level, supporting the microbial and biochemical environment that determines how well the barrier functions in the first place.

Skin with a balanced microbiome maintains barrier lipids and surface conditions more consistently, and that consistency is what translates into hydration that lasts. Natori Multibiome HD is designed around this mechanism, which is why its performance shows up most clearly in retention rather than in immediate uptake. Hydration and skin resilience are supported together rather than as two separate claims requiring two separate actives.

Formulation and Positioning Considerations

Natori Multibiome HD is suited to barrier repair moisturisers, sensitive skin ranges, post procedure care, and microbiome positioned lines where a credible mechanism is expected behind the marketing. It fits naturally alongside ceramide systems, humectant blends, and soothing actives, where it contributes a biological dimension that physical humectants cannot.

For teams already using beta glucan or a similar polysaccharide as the hydration workhorse, the comparative retention data provides a clear basis for evaluating a substitution or an addition. For teams building a new barrier first concept from the ground up, the postbiotic composition offers a differentiated foundation at a time when microbiome claims are increasingly scrutinised for substance.
