CYPERUS PAPYRUS LEAF CELL CULTURE EXTRACT.

Valuable CAS - / SKIN CONDITIONING

Cyperus Papyrus Leaf Cell Culture Extract, originating from native papyrus cells, is a multi-functional ingredient meticulously developed to enhance skin hydration and reinforce the skin's intrinsic barrier function. It works by replenishing the skin's water reservoir, reducing transepidermal water loss, and promoting essential lipid synthesis. Additionally, it provides robust antioxidant protection, contributing to cellular renewal and a resilient, hydrated complexion.

Summary

Antioxidant Hydrating Skin-Replenishing Soothing Regenerating Emollient Protective Barrier Repair

Science

Mechanism of Action

This extract operates by restoring skin hydration through a dual action: it replenishes the skin's internal water reserves and fortifies skin cohesion to counteract dehydration. It effectively limits transepidermal water loss by strengthening the bonds between corneocytes. The ingredient stimulates the production of crucial epidermal lipids, including free fatty acids, cholesterol, and ceramides, which are vital for maintaining a robust stratum corneum and its barrier integrity. Furthermore, it promotes cellular renewal, aiding in the formation of keratin, Natural Moisturizing Factor (NMF), and the hydrolipidic film, all essential components for optimal water retention within the epidermis. Beyond hydration, it offers regenerating, protective, lipid-replenishing, emollient, and antioxidant benefits.

Key findings

  1. 01 An 80% ethanol extract of C. papyrus demonstrated significant and complete cytoprotection against t-butyl hydroperoxide (TBHP) at a concentration of 100 µg/ml in hepa1c1c7 cells. It also exhibited direct antioxidant capabilities, with an EC50 of 5.1 µg/ml in the DPPH assay and a Ferric Reducing Antioxidant Power (FE) of 48.7 µg/ml in the FRAP assay.
  2. 02 Native papyrus cells effectively restore skin hydration by replenishing the skin's water reservoir and strengthening skin cohesion to prevent dehydration. This action limits insensible water loss, promotes the synthesis of critical lipids (free fatty acids, cholesterol, ceramides), and stimulates cellular renewal to contribute to the production of keratin, NMF, and the hydrolipidic film for enhanced water retention.
