perfuming soothing antioxidant astringent

Science

Functions through its high concentration of sesquiterpene alcohols (bulnesol and guaiol) which inhibit nitric oxide production and downregulate inflammatory markers including iNOS and COX-2. The astringent properties cause mild contraction of skin tissues and blood vessels, promoting a toning effect while reducing localized swelling.
