Piper Methysticum Leaf/Root/Stem Extract

An extract of the leaves, roots, and stems of Piper methysticum (kava), containing kavalactones including kavain, methysticin, and yangonin; used as a skin-conditioning agent at trace concentrations, with unresolved topical safety data per the CIR Expert Panel.

Kavalactones (kavain, methysticin, yangonin) contribute mild soothing propertiesSkin-conditioning agent that can help reduce moisture evaporationUsed at very low concentrations (0.0001–0.1%) in cosmetic formulas
CIR Expert Panel (2009) found data insufficient to support safety in cosmetics as used — use cautionOral kava consumption is associated with hepatotoxicity; dermal absorption and liver risk from topical use is unresolved
Soothing
Piper Methysticum Root Extract

Extract from the root of Piper methysticum (kava), a Piperaceae shrub native to Pacific Islands. Contains kavalactones (kavain, methysticin, yangonin, dihydromethysticin) and flavokawains. Topically, kavalactones modulate NF-κB and COX inflammatory signaling while polyphenols scavenge free radicals. The 2009 CIR Expert Panel found insufficient data to affirm topical safety owing to uncharacterized dermal absorption of hepatotoxic kavalactone constituents — used at very low concentrations in cosmetics.

CIR Expert Panel (2009) concluded available data were insufficient to support safety in cosmetics due to uncharacterized dermal absorption of kavalactones, which have an established hepatotoxicity profile via oral intake
