What it is
Achillea Millefolium Flower/Leaf/Stem Extract is a whole-aerial-part extract of yarrow that captures constituents from the flowers, leaves, and stems. It contains flavonoids, tannins, and other plant compounds and is used in cosmetics as a skin-conditioning and mildly astringent agent. It is generally added to the aqueous phase of creams, lotions, and toners.
Safety & warnings
Because yarrow is an Asteraceae (daisy/Compositae) plant, individuals sensitized to this family may rarely react. The extract can carry naturally occurring aromatic components relevant to fragrance-sensitive users. It is not regarded as comedogenic.
Origin & sourcing
Natural; derived from the above-ground parts of yarrow, Achillea millefolium, a member of the Asteraceae family.
