What Is Broussonetia Kazinoki Stem Extract?
Broussonetia Kazinoki Stem Extract comes from the woody stems of the Broussonetia kazinoki tree, a member of the mulberry family that grows across East Asia. The plant is better known for supplying fibers used in traditional Korean and Japanese paper, but its stems also hold a rich mix of natural compounds such as flavonoids, triterpenes and sugars that can soothe and smooth skin.
Interest in the extract began when local communities noticed that rinsing hands in cooled bark tea left skin feeling soft. Modern researchers isolated the stem portion and confirmed its skin-friendly profile, leading cosmetic chemists to adopt it as a gentle conditioning agent. To make the extract, harvested stems are dried, ground and steeped in a water-or-glycol solution. The liquid is then filtered and standardized so every batch offers consistent performance.
Today you will find Broussonetia Kazinoki Stem Extract in sheet masks, hydrating toners, daily moisturizers, lightweight serums and after-sun gels where it helps give a fresh, comfortable feel.

Who Can Use Broussonetia Kazinoki Stem Extract
The extract is generally well tolerated by all skin types including oily, dry, combination and sensitive because it focuses on conditioning rather than exfoliating or deeply active effects. Extremely reactive skin may still want to proceed cautiously, but there is no known reason the ingredient would be unsuitable for any particular skin type.
Because it is derived from plant stems and no animal by-products are involved in its harvesting or processing, Broussonetia Kazinoki Stem Extract is considered vegan and vegetarian friendly.

Comedogenic Rating
Rating: 0 / 5. Broussonetia Kazinoki Stem Extract is a water-soluble botanical with little to no fatty matter so it does not clog pores in lab tests or finished formulas.
