Spilanthes Acmella Flower Extract is a plant-derived ingredient rich in spilanthol, used in cosmetics for its purported muscle-relaxing and skin-smoothing effects that may temporarily reduce the appearance of expression lines. It is also studied for mild anti-inflammatory and antioxidant properties.
