Petasites Japonicus Root Extract
What is Petasites Japonicus Root Extract?
Petasites japonicus root extract comes from the rhizomes of Petasites japonicus, a perennial herbaceous plant in the Asteraceae family native to East Asia, including Japan and Korea. Known as Japanese butterbur, it has been utilized in traditional herbal practices. The extract is produced by processing the plant roots with solvents like water or glycerin to capture bioactive sesquiterpenes such as petasin and isopetasin. In cosmetic formulations, it functions primarily as a skin conditioning agent-miscellaneous, helping to improve skin texture, hydration, and comfort. Commonly found in moisturizers, serums, and facial masks, it contributes to product stability and sensory feel by forming a protective layer on the skin without clogging pores. Its mild nature makes it suitable for various skin types in rinse-off and leave-on products.
