Gleditsia Australis Thorn Extract

Gleditsia Australis Thorn Extract is sourced from the thorns of the honey locust tree (Gleditsia sinensis/australis), long used in traditional Korean and Chinese medicine as Zao Jiao Ci (皂角刺) for skin-clearing and anti-inflammatory purposes. The extract is rich in triterpenoid saponins, flavonoids, and alkaloids that contribute to its calming, clarifying, and sebum-modulating effects.
