What Is Polygonum Bistorta Root Extract?
Polygonum bistorta root extract is a plant ingredient that supplier research shows helps support two substances in skin’s dermal-epidermal junction, perlecan and its receptor site, dystroglycan. Perlecan is a proteoglycan, meaning a substance that contains a protein and glycosaminoglycan (hyaluronic acid is one). These are involved in keeping communication occurring in skin’s lower layers normalized since this crosstalk tends to breakdown significantly with age, leading to skin that looks dull, fatigued and uneven.
Applied to skin, polygonum bistorta root extract visibly revive radiances in a matter of weeks and restore a smoother surface. This includes around the eyes, softening the appearance of lines and wrinkles.
As with almost all plant extracts, it’s a good source of antioxidants. However, research has shown it’s a particularly potent antioxidant, rivaling the scavenging properties of vitamin C. It’s also quite soothing and future research may reveal more about how it calms signs of sensitivity.
Recommended usage levels of Polygonum bistorta root extract in skin care are 1–3%, where it’s supplied as a liquid combined with glycols.
