What Is Broussonetia Kazinoki Root Extract?
Broussonetia kazinoki root extract is derived from the root of the kazinoki tree, a species native to East Asia. It is used in skincare formulations primarily as a skin-conditioning agent, working to support the skin's texture and hydration levels.
In formulation, this extract functions as a humectant and emollient component, helping to improve how skin feels and appears by enhancing moisture retention and overall skin condition.
How It Works
Broussonetia kazinoki root extract functions as a skin conditioner by delivering compounds that interact with the skin's outer layers. It acts as both a humectant (drawing moisture into the skin) and a conditioning agent, helping to coat and smooth the stratum corneum (the skin's uppermost layer).
This combination of properties helps to improve the skin's ability to retain water and maintain hydration, which can result in a more comfortable, plump appearance.
Clinical Evidence & References
The clinical evidence base for this ingredient is limited. Most available data comes from ingredient supplier studies and traditional use in East Asian skincare rather than peer-reviewed independent research. These studies suggest the extract has skin-conditioning and hydrating properties, though the depth of evidence is modest compared to more established humectants.
More rigorous, published research would help establish its efficacy more definitively and identify optimal concentrations for consumer use.
How to Use
This ingredient is typically found in serums, moisturisers and essences. It works well when combined with other hydrating and conditioning ingredients such as glycerin or hyaluronic acid. There is no specific need to layer it in any particular order, though using it in a hydrating formula before or alongside an occlusive moisturiser can help lock in its benefits.
