ALPINIAWHITE

ALPINIAWHITE is an extract obtained from the seeds of Alpinia katsumadai, a traditional Chinese medicinal plant, developed by Ichimaru Pharcos. It activates the PLD1 signaling pathway, known as a melanin‑braking system, offering a novel whitening mechanism and allowing synergistic use with existing brightening ingredients; it is designated for use in Japanese quasi‑drug formulations.
