Science
Mechanism of Action
This botanical extract functions as a skin conditioning agent by creating a film on the skin's surface, which helps to minimize transepidermal water loss and maintain hydration. It also exhibits soothing and calming attributes, potentially alleviating skin irritation and redness. The active compounds, kavalactones, are known for analgesic properties and receptor modulation.

Safety Profile
The CIR Expert Panel found insufficient data to confirm the safety of this extract in cosmetics, citing concerns over potential liver effects from oral ingestion and a lack of dermal exposure data, including penetration, genotoxicity, irritation, and sensitization. The FDA issued a consumer advisory in 2002 regarding liver damage from ingested kava. Health Canada has banned or deemed kava extracts unsafe for cosmetic use, and some European countries restrict its importation.
