What Is Marrubium Vulgare Callus Extract?
Marrubium Vulgare Callus Extract comes from white horehound, a hardy herb in the mint family. Instead of harvesting the whole plant, scientists take a tiny piece of tissue and grow it in a sterile lab where it forms a callus, a mass of undifferentiated cells rich in protective molecules. This controlled environment lets manufacturers obtain a consistent supply free from soil contaminants or seasonal changes.
Chemically, the extract contains a mix of phenolic acids, flavonoids and other antioxidants that the plant produces to defend itself. These compounds translate to soothing and revitalizing effects when applied to skin. The use of plant cell culture technology gained traction in the early 2000s as brands looked for sustainable sources of potent botanicals. By growing the cells in bioreactors, companies avoid large-scale farming and reduce water and land use.
After the callus cells multiply, they are filtered, gently broken down and blended into a skin-friendly solvent such as glycerin or water. The resulting liquid is then standardized so each batch delivers the same level of active molecules.
You will typically find Marrubium Vulgare Callus Extract in serums, anti-aging creams, urban pollution defense products, masks and after-sun lotions where a light yet effective skin-soothing ingredient is desired.
