Saponaria Pumila Stem Cells

The plant of the Alpine scree. Able to survive rockfalls by constantly regenerating itself, saponaria pumila lends skin its extraordinary capacity for repair.

Did you know?A little history

On Alpine scree, a rolling stone can tear a plant out at any moment. Saponaria pumila developed a unique strategy: it constantly rebuilds its injured tissue, able to regrow even after being partially destroyed.

This extreme resilience caught the attention of plant biotechnologists in the 2010s: by growing its stem cells in the lab, they obtained an extract concentrated in repair mechanisms, without taking the rare plant from its natural habitat1.

Yon-Ka chose it for Time Resist Nuit, the moment when skin, too, repairs and renews itself.

General useNight, the time for repair

During sleep, skin is no longer challenged by UV or pollution: it's when it devotes the most energy to repairing itself and renewing its cells. Night creams are formulated to support this peak of regenerative activity.

Plant stem cells, not human ones: the extract is produced by culturing plant cells in the lab. It doesn't act on the skin's own stem cells, but delivers the regenerating metabolites the plant produces to repair itself.

Cosmetic useIts properties on skin

  • RegeneratingIt supports cell renewal during the nighttime repair phase1.
  • DensifyingIt helps maintain the skin's firmness and thickness.
  • Anti-agingIts antioxidant metabolites help prevent the signs of skin aging.
  • RepairingIt helps skin correct the accumulated marks of fatigue.
  • ProtectiveRich in plant defense compounds, it strengthens the skin's resistance to environmental stress.
