Vital essential oil is extracted from plants that grow in a harsh environment. For the “KOTOHA with yuica” series, we used our essential oil “yuica” extracted from forest trees in the natural environment. The energy of the intrinsic forest is stronger than that of organic plants. The fresh and deep aroma of Kuromoji (spice bush) is mainly derived from linalool. It features sedative and immunity-reinforcing action in addition to the moistening and repairing effects. The plant-based element, perisea, is blended, increasing the repairing power and facilitating damage recovery.
