Effect: All skin types, especially dry and atopic-prone skin.
Anti-inflammatory: Reducing inflammatory responses by decreasing the nuclear translocation of NF-κB and lowering the expression levels of pro-inflammatory cytokines (IL-8, TNF-α);
Soothing: Alleviating signs of irritation by deactivating the TRPA1 itch receptor;
Moisturiser: Preventing insensible water loss and maintaining adequate skin hydration by stimulating the synthesis of claudin-1 and ZO-1, two major proteins of tight junctions involved in cell-cell cohesion, and by increasing the levels of filaggrin in the horny layer, a component of natural moisturising factors (NMF), strengthening the barrier function and restructuring the epidermis, thanks to the polysaccharides contained in the roots.
Facial Care (serums, balms/repair creams, cleansers, night oils, soothing tonics);

Store in a cool, dry place, protected from moisture, heat, and direct sunlight.
Non-irritating and non-sensitising, the extract of the Ophiopogon japonicus is well tolerated by both adults and infants up to 5% in leave-on cosmetic products.
