About
Plant vesicles from Japanese knotweed root delivering resveratrol and emodin with strong antioxidant and anti-inflammatory skin benefits.
Polygonum Cuspidatum (Fallopia japonica) Root Extracellular Vesicles are secreted by cultured adventitious root cells. The vesicles carry resveratrol (trans-3,4',5-trihydroxystilbene), emodin, and polydatin as the primary active payload. Resveratrol is a stilbenoid that activates SIRT1 and Nrf2 pathways, upregulating endogenous antioxidant enzymes. Emodin is an anthraquinone with anti-inflammatory and antimicrobial properties. The combination is highly bioactive but emodin's quinone structure raises phototoxicity concerns when applied before UV exposure.
Skin benefits
- Strong antioxidant via Nrf2 activation
- Anti-inflammatory
- Anti-aging

Known concerns
- Emodin is a phototoxic quinone — may increase UV sensitivity
