What it is
Cuscuta Japonica Seed Extract is a plant-derived ingredient obtained from the seeds of Japanese dodder, a climbing parasitic vine used in traditional East Asian herbal practice. In cosmetics it is typically included at low levels as a botanical conditioning agent and is associated with antioxidant-type plant constituents such as flavonoids. It usually appears as a supporting botanical alongside other plant extracts rather than as a primary functional ingredient.
Safety & warnings
Botanical extracts can occasionally provoke sensitivity in individuals prone to plant-derived reactions, though this seed extract is not a recognized common allergen. The actual constituents depend heavily on the solvent and processing, so tolerability is largely governed by the finished formula.
Origin & sourcing
