Ingredient review
Lily of the Valley Callus Extract
INCI: CONVALLARIA MAJALIS CALLUS CULTURE EXTRACT
A gentle, lab-grown plant extract that may help protect skin from environmental stress, but research is still early.
In plain English
This ingredient is made by growing lily of the valley cells in a lab, then extracting beneficial compounds. It's not picked from wild plants, so it's more sustainable. In skincare, it's thought to calm irritation and defend against damage from pollution and UV light, but most evidence comes from lab studies, not large human trials.

What it is
A cosmetic ingredient produced by cultivating callus cells (undifferentiated plant cells) from Convallaria majalis (lily of the valley) in a controlled lab environment. The cells are harvested and processed to create an extract rich in antioxidants and soothing compounds.
How it works
The extract provides antioxidant compounds that neutralize free radicals caused by UV exposure and pollution. It may also reduce the production of inflammatory signals in skin cells, helping to calm redness and sensitivity. Because it's produced via biotechnology, the active compounds are consistent and free from contaminants found in wild-harvested plants.
Pros
Sustainable sourcing
Produced via plant cell culture, so no wild harvesting is needed, making it an eco-friendly choice.
Gentle antioxidant
Provides antioxidant benefits without the irritation that some stronger antioxidants (like pure vitamin C) can cause.
Cons and cautions
Limited research
Most evidence comes from lab studies; there are few peer-reviewed human trials confirming its effectiveness in skincare.
Potential allergen
Lily of the valley is a known allergen for some people, so patch testing is recommended before widespread use.
Best for
- People with sensitive or reactive skin looking for gentle antioxidant support
- Those interested in sustainable, biotech-derived ingredients
Use caution if
- Individuals with known allergies to lily of the valley or related plants
