“Hallabong (Jeju Citrus)”, a seasonal fruit harvested only during
winter on Jeju Island. It is named after the shape of its pointy
stalk end that resembles the peak of Mt. Halla.

The fruit is known for its rich Vitamin C content while its peel
contains various bioflavonoids, that provide the skin with firming
and brightening benefits.

As its peel is thicker than that of other fruits, it was difficult to
extract active ingredients. After conducting several tests on different
techniques, innisfree discovered that by using the ultrasonic
extraction approach, it can help to soften the Jeju
Hallabong peel and effectively extract the active ingredients to
create a whole new Brightening Pore Line.
