Ingredient review
Siberian Motherwort Callus Extract
INCI: Leonurus Sibiricus Callus Culture Extract
A lab-grown plant extract with antioxidant potential, but research on human skin is still limited.
In plain English
This ingredient is made by growing Siberian motherwort plant cells in a lab, then extracting their beneficial compounds. It's used in skincare to help protect skin from environmental damage and calm irritation. Because it's produced in a controlled lab, it's more sustainable and consistent than traditional plant harvesting.

What it is
A biotech-derived extract from the callus (undifferentiated plant cells) of Leonurus sibiricus, a plant traditionally used in herbal medicine. The callus culture method allows for a pure, sustainable, and standardized extract without harvesting wild plants.
How it works
The extract contains antioxidant compounds that help neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. It may also have anti-inflammatory properties that help soothe irritated skin, though the exact mechanisms are still being studied.
Pros
Sustainable sourcing
Lab-grown callus culture avoids harvesting wild plants, making it an eco-friendly choice.
Gentle antioxidant
Provides antioxidant benefits with a low risk of irritation, suitable for sensitive skin types.
Cons and cautions
Limited research
Most evidence comes from lab studies, not human trials, so real-world benefits are less certain.
Lower potency
As a callus extract, it may have lower concentrations of active compounds compared to whole-plant extracts.
Best for
- People looking for antioxidant protection in a sustainable ingredient
- Those with normal to combination skin seeking gentle soothing benefits
Use caution if
- Individuals with known allergies to plants in the Lamiaceae (mint) family
