BIOME-RXCELL™ is an exclusive biotechnological active developed for Puréality, in collaboration with the Bordeaux Science University, INRAE (National Research Institute for Agriculture, Food and the Environment), and a specialist partner in plant biotechnology.

Unlike conventional approaches, BIOME-RXCELL™ is not a “complex” made from several combined ingredients. It is a single, unique active, based on an innovative and proprietary encapsulation technology.

→ A prebiotic encapsulated at the core of a whole Rhodiola cell, obtained through botanical biotechnology.

This innovation allows two biological functions to coexist within one functional biological unit:

• an active targeting the skin microbiome,
  
• a fully intact plant cell, containing the complete DNA of the plant.
  

The result is a natural biological synergy that is more coherent and more effective for the skin.

BIOME-RXCELL™ is protected by a double biomimetic lipid membrane, which preserves the integrity of the active within the formula.

Upon contact with the skin:

• the membranes naturally fragment,
  
• the Rhodiola cell and the prebiotic are progressively released,
  
• the cellular components penetrate the stratum corneum and deliver their biological signals.
  

This targeted release maximises skin efficacy while respecting the skin’s natural ecosystem.

BIOME-RXCELL™ provides two complementary biological actions.

1. Targeted prebiotic action on the skin microbiome

The prebiotic:

• selectively nourishes beneficial skin bacteria,
  
• helps rebalance the skin’s ecosystem,
  
• strengthens the skin barrier,
  
• improves skin tolerance and comfort.
  

2. Cellular action of Rhodiola

Rhodiola, a well-known adaptogenic plant, helps to:

• improve cellular oxygenation,
  
• increase ATP production and therefore cellular energy,
  
• stimulate the activity of skin cells involved in firmness and radiance.

BIOME-RXCELL™ is not simply the combination of two actives, but their integration within a single cellular structure.

This biological architecture enables:

• optimal biological affinity with the skin,
  
• a progressive and coherent release of biological signals,
  
• a global action on both the skin microbiome and cellular vitality.
  

This biological coherence is what clearly differentiates BIOME-RXCELL™ from conventional cosmetic approaches.

BIOME-RXCELL™ is present in all Puréality formulations.

For example:

• the Rebalancing Essence, the brand’s hero product, contains 2.5 million cells in a 100 ml bottle.

• Plant stem cell: an undifferentiated cell (derived from callus tissue) capable of multiplying indefinitely.
  
• Whole cell: a differentiated cell obtained through cell culture from a stem cell.
  

At Puréality:

• the cells are native (non-GMO),
  
• the cells used are whole, intact cells, containing 100% of their DNA.
  

While most players use cell fragments, Puréality works with biologically complete cells, which are therefore more functional and more effective.

• Complex: a marketing-driven association of several separate actives.
  
• Active (BIOME-RXCELL™): a single active supplied as one unit, in which the prebiotic is encapsulated at the core of the Rhodiola cell.
  

This structure makes BIOME-RXCELL™ a true active, not a complex.

Many anti-ageing brands rely on:

• actives that stimulate cellular energy,
  
• prebiotics claiming an action on the skin microbiome.
  

The real differentiation therefore lies in:

• the method of production (biotechnology with low environmental impact),
  
• the biological efficacy of the active on the skin.
  

At Puréality:

• the prebiotic is protected inside the Rhodiola cell until delivery to the skin,
  
• Rhodiola nutrients are preserved by a double lipid membrane until cutaneous release.
  

As a result, BIOME-RXCELL™ delivers an action that is more targeted, more coherent and more effective than conventional cosmetic approaches.
