Expression lines usually become visible after the age of 30 and  are caused by repetitive movements of the facial muscles. Herbagen products against expression lines contain the revolutionary hexapeptide Argireline, oligopeptides from the okra plant and viper venom. Argireline has a proven effect on expression lines, clinical tests having shown a more youthful, relaxed skin and a decrease in wrinkle volume, length and texture after only a few days.

Viper venom and okra (Hibiscus esculentus) oligopeptides are active substances with a miorelaxing effect. They stimulate both the synthesis of collagen and the skin’s own self-defense mechanisms against free radicals.
