Erigeron Canadensis Flower Extract

Erigeron canadensis flower extract is derived from horseweed (also called Canadian fleabane), a plant native to North America. The extract is obtained from the flower portion of the plant and contains naturally occurring compounds with antioxidant properties.In skincare formulations, this ingredient functions primarily as an antioxidant and astringent, helping to protect skin from environmental stressors and support the skin's natural barrier function. It is typically used in modest concentrations within broader formulations rather than as a standalone active.

The antioxidant compounds within erigeron canadensis flower extract work by neutralising free radicals — unstable molecules that contribute to skin oxidative stress and premature ageing. By donating electrons to these unstable molecules, antioxidants stabilise them and prevent them from damaging skin cells.The astringent action is thought to arise from the plant's natural tannin content, which may create a mild tightening sensation on the skin surface, though this effect is typically subtle.

Erigeron canadensis flower extract is typically found in serums, toners, and moisturisers rather than concentrated treatments. As it is usually present in relatively low concentrations within formulations, it works best as part of a broader skincare routine that includes dedicated antioxidant and sun protection products. Use daily as directed by the specific product instructions.

Generally well-tolerated in cosmetic formulations. Those with known sensitivity to plants in the Asteraceae family (which includes ragweed and chrysanthemum) should patch test first, as cross-reactivity is theoretically possible.
