Field notes · Jeju Island, South Korea
It begins with a single green leaf.
Breathe out. This is the story of centella, the quiet plant at the heart of every seoul ritual, and the science that carries it to your skin.
On the volcanic landscapes of South Korea's Jeju Island, nature and innovation come together. Here, RIMAN cultivates Giant Centella, a botanical prized for its soothing and skin-conditioning properties. Rooted in Korean skincare heritage and refined through modern research, this remarkable ingredient embodies our belief that thoughtful skincare begins with nature.
Centella asiatica, known in Korea as byeongpul
A humble leaf with a long memory
Centella has been treasured across Asia for generations as a plant of comfort and care. It is the reason our formulas feel the way they do: gentle, soothing, quietly restorative.
You will find it throughout our rituals, from the Moisture Layer Sunscreen to the Radiansome™100 Concentrate, paired with madecassoside, one of the plant's own soothing compounds.
