Achillea Millefolium (yarrow) flower extract is a plant-derived ingredient used in skincare for its anti-inflammatory, antioxidant, and astringent properties. It is commonly added to formulations aimed at calming irritation and toning the skin.
| Reported effect | How often | Notes |
|---|---|---|
| Allergic contact dermatitis | Uncommon | Members of the Asteraceae (Compositae) family, including yarrow, can trigger sensitization in predisposed individuals, often due to sesquiterpene lactones. |
| Skin irritation or redness | Uncommon | Mild transient irritation may occur, particularly in sensitive skin or higher concentrations. |
| Photosensitivity | Rare | Yarrow contains constituents that may rarely increase sensitivity to sunlight. |
| Cross-reactivity with other Asteraceae plants | Rare | Individuals allergic to ragweed, chamomile, or chrysanthemum may react to yarrow extract. |
