Ingredient review
Ledebouriella Root Callus Extract
INCI: LEDEBOURIELLA SESELOIDES CALLUS CULTURE EXTRACT
A gentle, lab-grown root extract that may help calm irritation and defend against environmental stress, though human studies are limited.
In plain English
This ingredient is made by growing cells from the root of a plant called Ledebouriella seseloides (also known as Saposhnikovia divaricata) in a controlled lab environment. The resulting extract is rich in compounds like chromones and coumarins, which are thought to help soothe skin and fight damage from free radicals (unstable molecules that can harm skin cells). Because it's produced in a lab, it's consistent and doesn't require harvesting wild plants.

lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A biotechnologically produced extract from callus (undifferentiated plant cells) of the Ledebouriella seseloides root, standardized for active compounds like prim-O-glucosylcimifugin and cimifugin.
How it works
In cosmetic formulations, it is believed to work by providing antioxidant activity that neutralizes free radicals, and by reducing the production of pro-inflammatory molecules in skin cells, which may help calm redness and irritation.
Pros
Sustainably sourced
Produced via plant cell culture, so it doesn't require harvesting wild plants, making it an eco-friendly choice.
Gentle on skin
Has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Cons and cautions
Limited research
Most evidence comes from lab studies; there are few human trials confirming its effectiveness in real-world skincare.
Lower potency
Compared to well-established antioxidants like vitamin C or ferulic acid, its antioxidant power is less documented and likely weaker.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle antioxidant ingredient
Use caution if
- Individuals with known allergies to Apiaceae family plants (e.g., carrots, celery) should patch test first
Usage tips
Safety summary
Considered safe for cosmetic use with low irritation and comedogenic potential. As with any new ingredient, patch testing is recommended for those with plant allergies.
Research notes
In vitro studies suggest antioxidant and anti-inflammatory activity, but human clinical data is scarce. More research is needed to confirm efficacy in skincare.
