CETRARIA ISLANDICA THALLUS/POLYPODIUM VULGARE RHIZOME/SPHAGNUM MAGELLANICUM EXTRACT.

Valuable / HUMECTANT, SKIN CONDITIONING

A high-performance botanical complex derived from forest flora—Icelandic Moss, Fern, and Peat Moss—designed to function as an intelligent moisture manager. This synergistic blend provides deep-tier hydration while bio-mimetically restoring the skin's Natural Moisturizing Factor (NMF) and structural elasticity.

Science

This tri-active blend operates through three distinct pathways: Cetraria islandica (Lichen) creates a water-binding film using polysaccharides to prevent trans-epidermal water loss. Polypodium vulgare (Fern) utilizes Polypodine A to stimulate keratinocyte differentiation, effectively repairing the skin barrier. Finally, Sphagnum magellanicum (Moss) acts as a high-capacity reservoir, utilizing its hygroscopic properties to replenish moisture at a cellular level and simulate the skin's NMF.
