Scientific Evidence
Extensive in vitro and in vivo studies have explored the efficacy of Matrixyl and Argireline. Research suggests that Matrixyl can stimulate collagen synthesis and reduce wrinkle depth. Similarly, studies indicate that Argireline can reduce the appearance of expression lines by inhibiting muscle contractions. Further clinical trials are needed to fully elucidate the long-term effects and optimal usage of these peptides. Sources include journal articles indexed in PubMed and cosmetic ingredient databases.
