Propolis Extract
A resinous substance bees make from plant exudates, added to cosmetics for antioxidant and marketed "healing" properties. Contact-allergy reviews put patch-test positivity around 1 to 7 percent in tested dermatitis populations, concentrated in beekeepers and people already sensitized to fragrance or poplar-bud resins, so it is worth patch-testing if you have a history of contact allergies or bee-product sensitivity.
