Morus Bombycis (Kuwa) Root Extract
What is Morus Bombycis (Kuwa) Root Extract?
Morus Bombycis (Kuwa) Root Extract comes from the roots of the Morus bombycis tree, a mulberry species native to Japan also known as Kuwa. This botanical extract is prepared through solvent extraction to capture its natural compounds, including flavonoids and stilbenes. In cosmetic formulations, it functions primarily as a skin conditioning agent, typically incorporated into creams, serums, and lotions at low concentrations. It helps maintain skin's moisture balance, supports barrier integrity, and promotes a smooth, flexible texture by providing emollient and humectant-like effects. Authoritative databases like the EU CosIng classify it under skin conditioning-miscellaneous, highlighting its role in enhancing skin feel without altering structure. Its use draws from traditional Asian skincare practices, where root extracts are valued for gentle cosmetic benefits.
