In the dense forests, trees sometimes grow excessively, hindering each other's growth or causing nutrient imbalances within individual trees. To combat this, Hinok partners with the Jeju Plant Research Institute to implement 'pruning practices,' ensuring a harmonious ecosystem. By sourcing naturally fallen Hinoki branches from these efforts, we sustainably supply our raw ingredients.

To unlock the full potential of Hinoki, we conduct systematic research in our in-house laboratory nestled beneath the majestic Hallasan. Collaborating with the Natural Materials Application Research Institute, we execute comprehensive studies with each harvest, ensuring optimal efficacy. Our extraction process utilizes a gentle steam distillation method that only takes up for two hours, preserving the natural essence of the leaves and stems, without any additional chemical treatments.

As Hinoki Cypress Extract may contain natural impurities, we employ the Oxygen Refreshing technique, infusing oxygen from Jeju's pristine air into the extract. Conducted at our plant certified by Éve Vegan, a French certification specialized in the conformity of vegan products, this specialized process is free of chemicals and ensures a refreshing and clean Hinoki experience.

After extracting Hinoki Cypress Extract, the remaining branches, leaves, and stems undergo fermentation and are reused as compost to enrich the forest soil.
