What Is Polygonum Multiflorum Root Water?
Polygonum Multiflorum Root Water is a clear liquid obtained by steam-distilling the roots of the Polygonum multiflorum plant, also known as Fo-Ti or He Shou Wu. The distillation captures water-soluble compounds like mild plant acids, sugars and trace antioxidants that give the ingredient its cosmetic value. Fo-Ti has been prized in East Asian herbal traditions for centuries for its reputed hair and skin benefits, and modern formulators began tapping its gentler water extract when looking for botanical options that suit sensitive skin.
To make it, cleaned and sliced roots are placed in a still where steam passes through, lifting volatile and water-loving components. The vapor is condensed into an aqueous solution that is filtered and preserved, yielding Polygonum Multiflorum Root Water ready for cosmetic use.
You will usually find this ingredient in facial toners, hydrating mists, sheet masks, lightweight serums, anti-aging creams, soothing after-sun gels, scalp tonics and conditioning hair treatments where a botanical boost is desired without heavy oils.

Who Can Use Polygonum Multiflorum Root Water
This gentle plant water suits most skin types including dry, oily, combination and sensitive skin because it is lightweight and free of heavy oils. Those with very reactive or allergy-prone skin should still keep an eye on how their skin responds, as any botanical extract can be a trigger for some people.
Because it is derived solely from a plant root and no animal by-products are used during extraction or preservation, Polygonum Multiflorum Root Water is suitable for both vegans and vegetarians.
Current research shows no specific concerns for topical use during pregnancy or breastfeeding. That said, safety data is limited so this is not medical advice. Pregnant or nursing individuals should speak with their healthcare provider before adding any new skincare product to their routine.
The ingredient is not known to cause photosensitivity, so normal daytime use is fine without extra sun precautions beyond your usual SPF habits.
