What it is
Spilanthes acmella flower extract is obtained from a flowering herb traditionally known as the toothache plant or paracress, whose flowers are rich in alkylamides such as spilanthol. In cosmetics it is used as a skin-conditioning ingredient, often marketed for a smoothing, comfort-improving effect on the skin's appearance. In sunscreens it appears as a botanical conditioning additive rather than a UV filter.
Safety & warnings
Generally well tolerated as a botanical conditioning extract at cosmetic use levels. As with any plant extract, sensitive or allergy-prone individuals may occasionally react, and finished products may contain added fragrance to mask the raw extract's odor.
Origin & sourcing
A botanical extract sourced from the flowers of Spilanthes acmella (Acmella oleracea).
