Para cress contains spilanthol (N-2-Isobutyl-2,6,8-decatrienamide). Spilanthol reduces the muscle contractions of the mimic facial lines, and its relaxing influence causes a visible smoothing effect. The amino acids contained support the smoothing process by effectively retaining the skin moisture. In addition to that, the combination of the native liposomal phosphatidylcholine with DMS®-components adequately provides the skin with barrier substances. Although spilanthol belongs to the effective agents, i.e. the effects are only felt for a certain period of time, it can be applied as a long term treatment due to the above mentioned characteristics.
Note: Spilanthol is also contained in echinacea extract however in less concentrated form.
